| 1 | New radiocarbon and archaeobotanical evidence reveal the timing and route of southward dispersal of rice farming in south China显示文摘The origins and spreads of rice agriculture have been enduring topics, yet the timing and southward dispersal from the Yangtze River Basin have been difficult to trace, due to the scarcity of archaeobotanical data, especially systematic macro-plant remains examination, combined with the poor preservation in the humid climate and acidic soils of China's southern provinces.Here, we report new radiocarbon dating and preserved rice phytolith evidence, derived from three Late Neolithic archaeological sites in south China, dated about 5,000–4,100 cal a BP.Our results demonstrate that rice farming had spread southward through the mountainous regions of Wuyi and Nanling, then entered the areas of Western Fujian and North Guangdong by 5,000 cal a BP, followed by continued expansion into coastal areas of East China Sea and South China Sea, also crossing the Taiwan Strait, around 4,500–4,000 cal a BP.The North River,East River, Min River, and possibly other river systems likely were influential as pathways or conduits. | Xiaoyan Yang Qiuhe Chen Yongchao Ma Zhao Li Hsiao-chun Hung Qianglu Zhang Zhiwei Jin Suoqiang Liu Zhenyu Zhou Xianguo Fu | 2018 | Science Bulletin2018，63，22： | 9 |

| 3 | Isotopic evidence for soil water sources and reciprocal movement in a semi-arid degraded wetland:Implications for wetland restoration显示文摘Understanding water dynamics is a prerequisite for the restoration of degraded ecosystems in arid and semiarid regions.In this study,we carried out δD and δ^(18)O analyses of precipitation,unsaturated soil water,overland flow,surface runoff,and groundwater samples from a seasonally flooded wetland in the Momoge National Nature Reserve of the Songnen Plain,Northeast China,to identify the water sources and understand the mechanisms of unsaturated soil water movement.Unsaturated soil water content(W/W%)at every 20 cm along with a soil profile(0–100 cm)was collected during the growing season,and the HYDRUS-1D model was used to simulate temporal-spatial variations.The results showed that the local meteoric water line(δD=5.90δ18O-7.34,R2=0.95)had a smaller slope and intercept than the global meteoric water line because of strong evaporation at our study site under semi-arid climate.The groundwater was partly recharged by local precipitation via overland flow and unsaturated soil water infiltration.Unsaturated soil water was sourced from both precipitation and groundwater with variations at different depths.The upper soil layer at 0–15 cm was mainly sourced from limited precipitation,while the groundwater could move up to a 25 cm layer during the dry period.The unsaturated soil water content increased with soil depth in the top 40 cm,decreased at depths of 40 to 80 cm,and increased again at depths of 80 to 100 cm.The HYDRUS-1D model could simulate the unsaturated soil water dynamics well in the upper(0–40 cm)and lower(80–100 cm)sections,but poorly for depths of 40–80 cm due to the upward and downward flow.The bidirectional unsaturated soil water movement highlights the importance of capillary groundwater for wetland plants with similar climatic or hydrogeological conditions. | Yuanchun Zou Sijian Zhang Xiaofei Yu Guobin Fu Xianguo Lu | 2023 | Fundamental Research2023，3，6： | 1 |
| 4 | Relationship between plant species diversity and patch characteristics in a marsh in the Sangjiang Plain,China—Using Yaluhe farm as an example显示文摘Based on Quick Bird satellite image data, the present study examined small-scale herbaceous community patches in the marsh of the Sanjiang Plain and measured patch characteristics such as the area, perimeter and shape by GPS. The coenological characteristics of the patches were investigated using quadrat method, and the vascular plant species were recorded using transect method. A total of 219 plant species were recorded, which represents 12.2% of the vascular flora in Heilongjiang Province. Our results showed that species number S correlated with patch area and perimeter; richness index (R) correlated with patch perimeter; Simpson index (D) correlated with patch area and perimeter/area; Shannon-Wiener index (H′) correlated with patch area, perimeter and perimeter/area; Evenness index (Jsw) correlated with perimeter/area. Both S and R have significant difference between different size of patches. Plant diversity in the small-scale herbaceous communities tended to increase with the patch area and perimeter. We concluded that edge effects and the habitat heterogeneity of the patches are important in determining the number of species. The relative smoothness of the patch edges also affects the plant diversity of the patches. The richness of plant species in the marsh in the Sanjiang Plain is highly sensitive to the small-scale patches, which continues to play an important role in preserving plant diversity in the local area. | Sun Zhonglin Xing Fu Lu Xianguo Xu Kun Yu Lili Ni Hongwei | 2007 | Progress in Natural Science:Materials International2007，17，6： | 1 |
| 5 | Influencing factors of colostrum exposure to low-level lead and their relationship with early neural development of infants显示文摘BACKGROUND: Exposure to low-level lead has a toxic effect on the development of neonates, which has attracted wide attention. Colostrum lead level can be used as the indication of lead exposure. OBJECTIVE: To observe the relationship of colostrum lead level and the neurobehavioral development of infants. DESIGN: A prospective control observation. SETTING: Center for Maternal and Child Health, Shanxi Provincial Children's Hospital. PARTICIPANTS: Totally 128 neonates of full-term normal delivery, 76 male and 52 female, from Shanxi Provincial Maternal and Child Health Center and Jiexiu Maternal and Child Health Center were involved in this study. All the involved neonates had no peripartal ischemic/hypoxic history or fetus intrauterine developmental lag. Pregnant women had no various acute and chronic diseases in pregnancy, family history of neurological disease or occupational lead exposure. 128 portions of colostrum sample of full-term normal delivery were collected. Informed consents of detected items were obtained from the puerperants and their relatives. METHODS: ① Experimental grouping: Lead level in the colostrum was determined by atomic absorption spectrometry. According to lead level in the colostrum, the neonates were classified into two exposure groups of greater than or equal to 0.24 μmol/L in a high-level lead group and less than 0.24 μ mol/L in a low-level lead group. ② Experimental evaluation: Mental developmental index (MDI) and psychological developmental index (PDI) of 3-month-old infants were evaluated with Bayley Scales of Infant Development (BSID). The relationships of MDI, PDI and colostrum lead level were performed correlation regression analysis; The relationship of colostrum lead level and development was performed multi-factor analysis with family environment and health questionnaires. MAIN OUTCOME MEASURES: ① Evaluation results of MDI and PDI. ② Multi-factor analysis results. RESULTS: Totally 128 neonates were involved in the study. Ten and eleven neonates were lost due to emigration in the high-level lead group and low-level lead group respectively, and the other 107 neonates participated in the final analysis. ① MDI and PDI in the high-level lead group were significantly lower than those in the low-level lead group, respectively (P < 0.01); Regression analysis results showed that two developmental indexes were statistically negatively correlated with colostrum lead level (regression equation y = 1.9+0.01x1,-0.04x2,+0.04x3,+0.03x4). ② Four variables of the factors included by family environment and health questionnaires were taken into equation. Large maternal age, irrational dietary pattern in pregnancy and pollution degree of habitation environment in pregnancy were the risk factors of colostrum lead level (partial regression coefficien t =0.598 4,0.426 8,0.306 7,P < 0.05-0.01), and calcium supplementation in pregnancy was a protective factor (partial regression coefficien t =-0.455 8, P < 0.01). CONCLUSION: High colostrum lead level will have adverse effects on the early development of neonates; Large maternal age, irrational dietary pattern in pregnancy and pollution degree of habitation environment in pregnancy are the risk factors of colostrum lead level, and calcium supplementation in pregnancy was a protective factor. | Shiguang Li Guoping Wang Kui Fu Chunru Qi Xianguo Wu Qinghao Kong Yingyi Liang | 2007 | Neural Regeneration Research2007，2，9： | 1 |
