| 1 | Mapping wetland changes in China between 1978 and 2008显示文摘Four wetland maps for all China have been produced,based on Landsat and CBERS-02B remote sensing data between 1978 and 2008 (1978,1990,2000 and 2008).These maps were mainly developed by manual interpretation and validated by substantial field investigation in 2009.Based on these maps,we analyzed the 2008 wetland distribution in China and discussed wetland changes and their drivers over the past 30 years.(i) There were about 324097 km 2 of wetlands in 2008,for which inland marshes or swamps were the most common wetland type (35%),with lakes (26%) second.Most of the wetlands were in Heilongjiang,Inner Mongolia,Qinghai and Tibet,occupying about 55% of the national wetland area.(ii) From 1978 to 2008,China's wetland area continually and significantly decreased,by about 33% based on changes in the wetland map.This was in sharp contrast to the increase in artificial wetlands,which increased by about 122%.Inland marshes accounted for the main loss of total wetlands from 1978 to 2000.From 2000 through 2008,riverine and lacustrine wetlands constituted the main wetland loss.Fortunately however,the rate of wetland loss decreased from 5523 to 831 km 2 /a.(iii) The change ratio of lost natural wetlands (including inland and coastal wetlands) to non-wetlands has decreased slightly over the past 30 years.From 1978 to 1990,nearly all natural wetlands (98%) lost were transformed into non-wetlands.However,the ratio declined to 86% from 1990 to 2000,and to 77% from 2000 to 2008.(iv) All Chinese provinces were divided into three groups according to patterns of wetland changes,which could relate to the driving forces of such changes.Tibet was completely different from other provinces,as it was one representative example in which there was a net wetland increase,because of global warming and decreased human activity since 1990.Increased economic development caused considerable wetland loss in most eastern provinces,and artificial wetlands increased. | NIU ZhenGuo ZHANG HaiYing WANG XianWei YAO WenBo ZHOU DeMin ZHAO KuiYi ZHAO Hui LI NaNa HUANG HuaBing LI CongCong YANG Jun LIU CaiXia LIU Shuang WANG Lin LI Zhan YANG ZhenZhong QIAO Fei ZHENG YaoMin CHEN YanLei SHENG YongWei GAO XiaoHong ZHU WeiHong WANG WenQing WANG Hong WENG YongLing ZHUANG DaFang LIU JiYuan LUO ZhiCai CHENG Xiao GUO ZiQi GONG Peng | 2012 | Chinese Science Bulletin2012，57，22： | 51 |
| 2 | Protection efficacy of national wetland reserves in China显示文摘Wetlands have the most abundant biodiversity,the highest carbon sequestration capacity,and the highest values for ecological services per unit area,of all the world's ecosystems.Practice has shown that establishing reserves is the most effective way of protecting typical ecosystems and their biodiversity,and saving rare or endangered wildlife.The Chinese government's policy is to protect wetland systems by establishing reserves that encompass a massive network of wetlands,including wetland nature re-serves,internationally important wetlands,and wetland parks.Many are already established.The effect of protecting wetland nature reserves at the national level has not yet been reported.We used the latest database evaluating the protection value of wet-land reserves,and remotely sensed wetland maps(1978-2008) ,developed by the same mapping specialists and based on the same classification system,and related environmental data,to evaluate the effects of protecting China's national wetland reserves over the last 30 years.We conclude that(i) the total area of wetland in the national wetland reserves has decreased over the last 30 years to 8152.47 km2,and just 8% of China's net decrease in wetlands;(ii) about 79% of the 91 national wetland reserves are in a poor condition.These are generally located around the Yangtze River,Eastern Coast,the Three Rivers Source,and Southwest China.Protection measures should be undertaken urgently in these areas.Only 15% of national wetland reserves are under sound protection,and these are generally located in the upper reaches of the Songhua River;(iii) although 88% of national wetland re-serves are primitive(relatively natural) ,implying that the site selection has been scientific,a high percentage of national wetland reserves show early warning signs of decline and require urgent attention;(iv) based on our evaluation of protection effects and pressures on ecology,we have made a priority list of national wetland reserves,and propose several protection strategies. | ZHENG YaoMin ZHANG HaiYing NIU ZhenGuo GONG Peng | 2012 | Chinese Science Bulletin2012，57，10： | 29 |
| 3 | Preliminary estimation of the organic carbon pool in China's wetlands显示文摘Accurate estimation of wetland carbon pools is a prerequisite for wetland resource conservation and implementation of carbon sink enhancement plans.The inventory approach is a realistic method for estimating the organic carbon pool in China's wetlands at the national scale.An updated data and inventory approach were used to estimate the amount of organic carbon stored in China's wetlands.Primary results are as follows:(1) the organic carbon pool of China's wetlands is between 5.39 and 7.25 Pg,accounting for 1.3%-3.5% of the global level;(2) the estimated values and percentages of the organic carbon contained in the soil,water and vegetation pools in China's wetlands are 5.04-6.19 Pg and 85.4%-93.5%,0.22-0.56 Pg and 4.1%-7.7%,0.13-0.50 Pg and 2.4%-6.9%,respectively.The soil organic carbon pool of China's wetlands is greater than our previous estimate of 3.67 Pg,but is lower than other previous estimates of 12.20 and 8-10 Pg.Based on the discussion and uncertainty analysis,some research areas worthy of future attention are presented. | ZHENG YaoMin NIU ZhenGuo GONG Peng DAI YongJiu SHANGGUAN Wei | 2013 | Chinese Science Bulletin2013，58，6： | 13 |
| 4 | Assessing the ecological vulnerability of protected areas by using Big Earth Data显示文摘The ecological vulnerability of global protected areas(PAs)is linked to the 2030 United Nations Sustainable Development Goals.We developed a novel degree of ecological vulnerability(DEV)index based on Big Earth Data to assess the ecological vulnerability of PAs.This is a transparent,repeatable,large-scale and rapid assessment method.We applied the method to case studies of International Union for Conservation of Nature(IUCN)PAs in the basins of the Aral Sea,the Caspian Sea,the Black Sea and the Lake Baikal.Between 2001 and 2015,the spatial pattern of ecological vulnerability in the study area was relatively stable.The Caspian Sea basin and protected landscape/seascape(category V)showed high ecological vulnerability,while the Black Sea basin and wilderness areas(category Ib)showed low ecological vulnerability.Big Earth Data shows great vitality in PAs ecological vulnerability assessment.Strengthening international cooperation is an important means to break the bottleneck of ecological environment and resource endowment in these important international basins. | Yaomin Zheng Shudong Wang Yue Cao Jinlian Shi Yi Qu Liping Li Tianjie Zhao Zhenguo Niu Rui Yang Peng Gong | 2021 | International Journal of Digital Earth2021，14，11： | 3 |
| 5 | A Method for Alpine Wetland Delineation and Features of Border: Zoigê Plateau, China显示文摘Accurate wetland delineation is the basis of wetland definition and mapping, and is of great importance for wetland management and research. The Zoigê Plateau on the Qinghai-Tibet Plateau was used as a research site for research on alpine wetland delineation. Several studies have analyzed the spatiotemporal pattern and dynamics of these alpine wetlands, but none have addressed the issues of wetland boundaries. The objective of this work was to discriminate the upper boundaries of alpine wetlands by coupling ecological methods and satellite observations. The combination of Landsat 8 images and supervised classification was an effective method for rapid identification of alpine wetlands in the Zoigê Plateau. Wet meadow was relatively stable compared with hydric soils and wetland hydrology and could be used as a primary indicator for discriminating the upper boundaries of alpine wetlands. A slope of less than 4.5° could be used as the threshold value for wetland delineation. The normalized difference vegetation index(NDVI) in 434 field sites showed that a threshold value of 0.3 could distinguish grasslands from emergent marsh and wet meadow in September. The median normalized difference water index(NDWI) of emergent marsh remained more stable than that of wet meadow and grasslands during the period from September until July of the following year. The index of mean density in wet meadow zones was higher than the emergent and upland zones. Over twice the number of species occurred in the wet meadow zone compared with the emergent zone, and close to the value of upland zone. Alpine wetlands in the three reserves in 2014 covered 1175.19 km2 with a classification accuracy of 75.6%. The combination of ecological methods and remote sensing technology will play an important role in wetland delineation at medium and small scales. The correct differentiation between wet meadow and grasslands is the key to improving the accuracy of future wetland delineation. | ZHENG Yaomin NIU Zhenguo GONG Peng LI Mengna HU Lile WANG Lei YANG Yuxiang GU Hai-jun MU Jinrong DOU Gejia XUE Hui WANG Lin LI Hua DOU Gejie DANG Zhicairang | 2017 | Chinese Geographical Science2017，27，5： | 2 |

| 9 | Geographic range size patterns across plants and animals of Xinjiang,China显示文摘Patterns in species geographic range size are relatively well-known for vertebrates,but still poorly known for plants.Contrasts of these patterns between groups have rarely been investigated.With a detailed flora and fauna distribution database of Xinjiang,China,we used regression methods,redundancy analysis and random forests to explore the relationship of environment and body size with the geographic range size of plants,mammals and birds in Xinjiang and contrast these patterns between plants and animals.We found positive correlations between species range size and body size.The range size of plants was more influenced by water variables,while that of mammals and birds was largely influenced by temperature variables.The productivity variable,i.e.,Enhanced Vegetation Index(EVI)was far more correlated with range size than climatic variables for both plants and animals,suggesting that vegetation productivity inferred from remote sensing data may be a good predictor of species range size for both plants and animals. | LiPing Li ChunYan Zhang Eimear Nic Lughadha Tarciso CCLeão Kate Hardwick YaoMin Zheng HuaWei Wan Ming Ma Nurbay Abudusalih Ying Hai Zhen Pu JiangShan Lai ZhanFeng Shen Li Liu Tuo Wang YangMing Jiang HuiHui Zhao QingJie Liu | 2022 | Research in Cold and Arid Regions2022，14，1： | 0 |
| 10 | Red list assessments of Chinese higher plants显示文摘Based on the two most recent assessments of Chinese higher plants in 2013 and 2020,of 34,450 and 39,330 species,respectively,we analysed the threatened status of Chinese higher plants.In 2020,around 4,088(10.39%)of the assessed species in China are threatened,2,875(7.31%)Near Threatened,27,593(70.16%)not currently threatened and categorised as Least Concern and 4,752(12.08%)categorised as Data Deficient.While in 2013,3,767(10.93%)of the assessed higher plants in China are threatened,2,723(7.90%)Near Threatened,24,296(70.53%)Least Concern and 3,612(10.48%)Data Deficient.Estimates of the Red List Index in the two years show different patterns when using different weighting methods with the equal steps weighting method showing a slight decrease(0.91675-0.91495)and the extinction risk weighting method showing a slight increase(0.98792-0.98797).We inferred that China's threatened plant species were likely/relatively effectively protected.However,attention should also be given to the non-threatened species in the future as an additional strategy for their conservation,to maintain their non-threatened status. | Liping Li Haining Qin Eimear Nic Lughadha Yaomin Zheng Huawei Wan Jack Plummer Melanie-Jayne R.Howes Huiyuan Liu Yangming Jiang Tuo Wang Huihui Zhao Zhanfeng Shen Huiping Huang | 2023 | International Journal of Digital Earth2023，16，1： | 0 |
| 11 | Geochemistry of mafic rocks and melt inclusions and their implications for the heat source of the 14.0°S hydrothermal field, South Mid-Atlantic Ridge显示文摘Fresh rocks sampled from the 14.0°S hydrothermal field of the South Atlantic Ridge can be divided into two categories: olivine-gabbro and basalt. The olivine-gabbro is composed mainly of three types of minerals: olivine, clinopyroxene and plagioclase, while a multitude of melt inclusions occur in the plagioclase phenocrysts of the basalts. We analyzed the whole-rock, major and trace elements contents of the basalts, the mineral chemistry of phenocrysts and melt inclusions in the basalts, and the mineral chemistry of olivine-clinopyroxene-plagioclase in the olivine-gabbro, then simulated magma evolution within the crust using the COMAGMAT program. The whole-rock geochemistry shows that all the basalts exhibit typical N-MORB characteristics. In addition, the mineral chemistry characteristics of the olivine-gabbro(low-Fo olivine, low-Mg# clinopyroxene, high-Ti O2 clinopyroxene, low-An plagioclase), show that strong magma differentiation occurred within the crust. Nevertheless, significant discrepancies between those minerals and phenocrysts in the basalts(high-Fo olivine, high-An plagioclase) reflect the heterogeneity of magma differentiation. High Mg#(≈0.72) melt inclusions isobaric partial crystallization simulations suggest that the magma differentiation occurred at the depth shallower than 13.03 km below the seafloor, and both the vertical differentiation column shows distinct discrepancies from that of a steady-state magma chamber. Instead, a series of independent magma intrusions probably occurred within the crust, and their corresponding crystallized bodies, as the primary high-temperature thermal anomalies within the off-axis crust, probably act as the heat source for the development of the 14.0°S hydrothermal system. | LI Bing SHI Xuefa YANG Yaomin YE Jun GAO Jingjing ZHENG Wenqin | 2014 | Chinese Journal Of Geochemistry2014，33，4： | 0 |
