| 1 | Saline dust storms and their ecological impacts in arid regions显示文摘In many arid and semiarid regions,saline playas represent a significant source of unconsoli-dated sediments available for aeolian transport,and severe saline dust storms occur frequently due to human disturbance.In this study,saline dust storms are reviewed systematically from the aspects of con-cept,general characteristics,conditions of occurrence,distribution and ecological impact.Our researches showed that saline dust storms are a kind of chemical dust storm originating in dry lake beds in arid and semiarid regions;large areas of unconsolidated saline playa sediments and frequent strong winds are the basic factors to saline dust storm occurrence;there are differentiation characteristics in deposition flux and chemical composition with wind-blown distance during saline dust storm diffusion;and saline dust storm diffusion to some extent increases glacier melt and results in soil salinization in arid regions.An under-standing of saline dust storms is important to guide disaster prevention and ecological rehabilitation. | Jilili Abuduwaili | 2010 | Journal of Arid Land2010，2，2： | 21 |
| 2 | Spatial distribution of soil moisture,salinity and organic matter in Manas River watershed,Xinjiang,China显示文摘With the classical statistical and geostatistical methods,the study of the spatial distribution and its influence factors of soil water,salinity and organic matter was carried out for 0-70 cm soil layers in Manas River watershed.The results showed that the soil moisture data from all soil layers exhibited a normal distribution,with average values of 14.08%-21.55%.Geostatistical analysis revealed that the content of soil moisture had a moderate spatial autocorrelation with the ratios of nugget/sill ranging from 0.500 to 0.718,which implies that the spatial pattern of soil moisture is influenced by the combined effects of structural factors and random factors.Remarkable spatial distributions with stripped and mottled features were found for soil moisture in all different soil layers.The landform and crop planting had a relatively big influence on the spatial distribution of soil moisture;total soil salinity was high in east but low in west,and non-salinized soil and lightly salinized soil appeared at the northwest and southwest of the study area.Under the effect of reservoir leakage,the heavily salinized soils are widely distributed in the middle of the study area.The areas of the non-salinized and lightly salinized soils decreased gradually with soil depth increment,which is contrary to the case for saline soils that reached a maximum of 245.67 km2 at the layer of 50-70 cm.The types of soil salinization in Manas River watershed were classified into four classes:the sulfate,chloride-sulfate,sulfate-chloride and chloride.The sulfate salinized soil is most widely distributed in the surface layer.The areas of chloride-sulfate,sulfate-chloride,and chloride salinized soils increased gradually along with the increment of soil depth;the variation range of the average values of soil organic matter content was between 7.48%-11.33%.The ratios of nugget/sill reduced gradually from 0.698 to 0.299 with soil depth increment,which shows that the content of soil organic matter has a moderate spatial autocorrelation.The soil organic matter in all soil layers met normal distribution after logarithmic transformation.The spatial distribution patterns of soil organic matter and soil moisture were similar;the areas with high organic matter contents were mainly distributed in the south of the study area,with the lowest contents in the middle. | Jilili ABUDUWAILI Yang TANG Mireban ABULIMITI DongWei LIU Long MA | 2012 | Journal of Arid Land2012，4，4： | 9 |
| 3 | The climatic and hydrological changes and environmental responses recorded in lake sediments of Xinjiang,China显示文摘Based on the analyses of environmental proxy data in lake sediments and instrumental records of Xinjiang in northwest China,the Holocene climate and hydrological variability and its environmental responses were studied in different time scales and regions. The results showed that the Holocene climate variability had obvious differences between the north and south of Xinjiang. In northern Xinjiang,the Holocene climate was dry in the early period,humid in the middle period,and then changed to dry in the late period. However,the climate transition times were not consistent in different regions. In southern Xinjiang,although there were many different types of climate change patterns inferred from different catchments,the warm and wet climate was recorded in most lake sediments in the middle Holocene. According to comparisons of some millennium scale records in lake sediments,the climate was warm and dry in the past 100 years. It can be concluded the climate showed a trend of aridity in Holocene. Especially in recent 50 years,the lake area has been shrinking rapidly because of the population growth and social economic development,which brings some environmental problems. Lake level and area changes were sensitively affected by the climate variation in geological history of Xinjiang and the lake level will continue to shrink because of the drought climate and strengthened human activities. | Long MA JingLu WU Jilili Abuduwaili | 2011 | Journal of Arid Land2011，3，1： | 5 |
| 4 | Migration and accumulation of heavy metals in disturbed landscapes in developing ore deposits, East Kazakhstan显示文摘This paper studied the contents of heavy metals and their accumulation in the disturbed landscapes in ore deposits of East Kazakhstan. A total of 14 sites were examined in Zyrynovsky and Tishinsk deposits and Ridder town, and 50 soil samples were taken. Results indicated that the contents of heavy metals in the soil reached the maximum permissible concentration. Emissions of the zinc plant negatively affected the soil of nearby territories. In the remediated areas, a high concentration of heavy metals was observed at a depth where the bulk soil borders the rock. Accumulation of heavy metals on the surface of the remediated areas occurred due to biological accumulation in the plant. Plants transmitted heavy elements through the root system to the upper vegetative organs, making them accumulate in the upper layers of the soil. The heavy metals migrated and accumulated from the lower layers to the surface layers of the soil. The absence of soil meso-fauna resulted in the contamination of soil by heavy metals. The analysis of water samples, taken from the waste storages and the waste waters with heavy metals in the Zyryanovsk deposit and Ridder town, revealed severe water contamination. | Gulzhan BEISEYEVA Jilili ABUDUWALI | 2013 | Journal of Arid Land2013，5，2： | 3 |
| 5 | Challenges for the sustainable use of water and land resources under a changing climate and increasing salinization in the Jizzakh irrigation zone of Uzbekistan显示文摘Jizzakh Province in Uzbekistan is one of the largest irrigated areas in Central Asia without natural drainage.In combination with aridity,climate change and extensive irrigation practices,this has led to the widespread salinization of agricultural land.The aim of this study was to identify opportunities to improve the reclamation status of the irrigated area and how best to effectively use the water resources in Jizzakh Province based on investigations conducted between 1995 and 2016.A database of field measurements of groundwater levels,mineralization and soil salinity conducted by the provincial Hydro-Geological Reclamation Expeditions was used in the study.The total groundwater mineralization was determined using a portable electric conductometer(Progress 1T)and the chloride concentration was determined using the Mohr method.The soil salinity analyses were conducted by applying two different methods:(1)the extraction and assessment of the soluble salt content,and(2)using an SM-138 conductivity sensor applied to a 1:1 mixture of soil sample and water.The analyses of the monitoring results and the salt balance in the'irrigation water–soil–drainage water'system clearly demonstrated that the condition of the irrigated land in the province was not significantly improved.Under these conditions,the stability of crop yields is achieved mainly through the use of large volumes of fertilizer.However,excess amounts of mineral fertilizers can also cause the salinization of soils.The average groundwater salinization value in most of the irrigated land(75.3%)fluctuated between 1.1 and 5.0 g/L,while the values were less than 1.0 g/L in 13.1%of the land and in the range of 5.1–10.0 g/L in 10.5%of the land.During the period of 1995–2016 the salinization level of the irrigated land in Jizzakh Province increased slightly and the area could be divided into the following classes:no salinity(17.7%of the total area),low salinity(51.3%),moderate salinity(29.0%),and high salinity(2.0%).Detailed studies of the salt balance in irrigated land,the impact of climate change,increased fertilizer use,and repeated remediation leaching on the groundwater level and mineralization should be conducted in the future,due to the possibility of accelerated salinization,fertility decline,and reduced yields of agricultural crops. | Rashid KULMATOV Jasur MIRZAEV Jilili ABUDUWAILI Bakhtiyor KARIMOV | 2020 | Journal of Arid Land2020，12，1： | 2 |
| 6 | Spatial differentiation in stable isotope compositions of surface waters and its environmental significance in the Issyk-Kul Lake region of Central Asia显示文摘Stable isotope values of oxygen(^(18)O) and hydrogen(^(2)H) of surface waters were used to study the origin and environmental significances in the Issyk-Kul basin of Kyrgyzstan in Central Asia, which is the most important intermountain basin in the modern Tien Shan orogen. This study is the first analysis of hydrochemical spatial differentiation in the stable isotopes of surface waters in this watershed.75 samples were collected from rivers, springs, lakes,rain and snow during the rainy season in July and August of 2016. Stable isotopes of ^(18)O and ^(2)H were studied for all samples, and cation ratios(Sr/Ca and Mg/Ca) were also determined for lake water samples.Stable isotope values from precipitation scattered around the Local Meteoric Water Line(determined from Urumqi Station of the global network of isotopes in precipitation(GNIP)), together with values of the Deuterium excess parameter(d) from 15.3‰ to30.5‰, with an average of 19.8‰, indicating that the moisture sources are primarily from regions with low relative humidity. The δ^(18)O and δ^(2)H values were significantly different between the river and lake samples, indicating that regional evaporation caused the isotopic enrichment of lake water. Geospatial autocorrelation, measured by Moran's I coefficient,indicated weak spatial autocorrelation within stable isotopes of oxygen and hydrogen in the surface waters of the studied area, which is primarily an effect of climate during the water chemistry evolution. The cation ratios Sr/Ca and Mg/Ca in lake water samples were not correlated with the concentration of total dissolved solids, but did show correlation with stable isotopic values, which is significant for paleoenvironmental reconstruction. | MA Long JILILI Abuduwaili LI Yao-ming | 2018 | Journal of Mountain Science2018，15，2： | 2 |

| 8 | Long-term variations in runoff of the Syr Darya River Basin under climate change and human activities显示文摘In this study,we analyzed the hydrological and meteorological data from the Syr Darya River Basin during the period of 1930–2015 to investigate variations in river runoff and the impacts of climate change and human activities on river runoff.The Syr Darya River,which is supplied by snow and glacier meltwater upstream,is an important freshwater source for Central Asia,as nearly half of the population is concentrated in this area.River runoff in this arid region is sensitive to climate change and human activities.Therefore,estimation of the climatic and hydrological changes and the quantification of the impacts of climate change and human activities on river runoff are of great concern and important for regional water resources management.The long-term trends of hydrological time series from the selected 11 hydrological stations in the Syr Darya River Basin were examined by non-parametric methods,including the Pettitt change point test and Mann-Kendall trend tests.It was found that 8 out of 11 hydrological stations showed significant downward trends in river runof f.Change of river runoff variations occurred in the year around 1960.Moreover,during the study period(1930–2015),annual mean temperature,annual precipitation,and annual potential evapotranspiration in the river basin increased substantially.We employed hydrological sensitivity method to evaluate the impacts of climate change and human activities on river runoff based on precipitation and potential evapotranspiration.It was estimated that human activities accounted for over 82.6%–98.7%of the reduction in river runoff,mainly owing to water withdrawal for irrigation purpose.The observed variations in river runoff can subsequently lead to adverse ecological consequences from an ecological and regional water resources management perspective. | Sanim BISSENBAYEVA Jilili ABUDUWAILI Assel SAPAROVA Toqeer AHMED | 2021 | Journal of Arid Land2021，13，1： | 1 |
| 9 | An extreme rainfall event in summer 2018 of Hami city in eastern Xinjiang, China显示文摘Extreme rainfall events are rare in inland arid regions, but have exhibited an increasing trend in recent years, causing many casualties and substantial socioeconomic losses. A series of heavy rains that began on July 31st, 2018, battered the Hami prefecture of eastern Xinjiang, China for four days. These rains sparked devastating floods, caused 20 deaths, eight missing, and the evacuation of about 5500 people. This study examines the extreme rainfall event in a historical context and explores the anthropogenic causes based on analysis of multiple datasets (i.e., the observed daily data, the global climate models (GCMs) from the Coupled Model Intercomparison Project Phase 5 (CMIP5), the NCEP/NCAR Reanalysis 1, and the satellite cloud data) and several statistical techniques. Results show that this extraordinarily heavy rainfall was due mainly to the abnormal weather system (e.g., the abnormal subtropical high) that transported abundant water vapor from the Indian Ocean and the East China Sea crossed the high mountains and formed extreme rainfall in Hami prefecture, causing the reservoir to break and form a flood event with treat loss, which is a typical example of a comprehensive analysis of the extreme rainfall event in summer in Northwest China. Also, the fraction of attributable risk (FAR) value was 1.00 when the 2018 July–August RX1day (11.52 mm) was marked as the threshold, supporting the claim of a significant anthropogenic influence on the risk of this extreme rainfall. The results offer insights into the variability of precipitation extremes in arid areas contributing to better manage water-related disasters. | ZOU Shan DUAN Wei-Li Nikolaos CHRISTIDIS Daniel NOVER ABUDUWAILI Jilili Philippe De MAEYER Tim Van De VOORDE | 2021 | Advances in Climate Change Research2021，12，6： | 1 |

| 16 | Irrigation erosion of irrigated soils in the foothills of southern Kazakhstan显示文摘This paper presented the results from the study of irrigation erosion of irrigated lands in southern Kazakhstan. The main purpose of the work is the conservation of the fertility of irrigated soils, and then the soils of the upper, middle and lower sections of the slopes at the experimental site were studied. Based on field investigations, authors studied the water resistance of aggregates of gray-brown soils and light gray soils before and after irrigation and qualitative indicators of changes in physical and chemical properties of structured soils in irrigation were determined by conventional methods of soil research. The results indicated that the changes in the physical properties of soils by using polymeric compounds created a fundamentally new opportunity to control water erosion of soils. | Abdulla S SAPAROV Enadiy K МIRZAKEEV Tatyana M SHARYPOVA Galymzhan A SAPAROV Jilili ABUDUWAILI | 2013 | Journal of Arid Land2013，5，2： | 1 |
