Research on the recharge of the lakes in the Badain Jaran Desert: Simulation study in the Sumu Jaran lakes area

Jing Zhang, HU Xiaonong, Huiting Lu, Zhen Ma

巴丹吉林沙漠气候干旱，蒸发强烈，与之形成鲜明对比的是沙漠腹地湖泊群的长久不衰，目前对于湖泊水分的补给来源仍存在争议.本文以水量均衡为基础，在苏木吉林湖区开展了降水、蒸发及湖水位和地下水位的动态监测，结合已有的水文地质资料建立地下水流动三维模型，重现湖区地下水位的季节动态变化，并基于模型进行水均衡分析.结果表明：苏木吉林湖区降水入渗补给量不足以平衡湖泊蒸发量，湖泊需要深层承压水的越流补给；湖水位和地下水位均呈现正弦曲线形态，11月最低，4月达到峰值，水位变幅分别为22和18 cm；湖区地下水多年平均总补给量为11620 m3/d，其中降水和承压水越流分别约占13%和87%，降水补给量夏季高、冬季低，承压水越流补给量季节变化不明显；承压水越流补给量可能主要来源于沙漠周边山区降水，未发现明显的水量亏空需要断裂导水来弥补.研究结果为巴丹吉林沙漠地下水资源分析及合理利用提供科学依据.;The Badain Jaran Desert was located at the northwest inland of China with drought and intensive evaporation. In stark contrast, there were dozens of permanent lakes inside the desert hinterland. Water recharge of the lakes in the Badain Jaran Desert …

Clines in salt lakes in the Badain Jaran Desert and their significances in indicating fresh groundwater discharge

Wang Xu-sheng, HU Xiaonong, Huiting Lu, Yanping Gong

位于阿拉善高原的巴丹吉林沙漠分布有大量盐湖.为揭示盐湖分层特征以及地下水对盐湖水体的影响,选取沙漠腹地的第二大盐湖——苏木巴润吉林,对9月份湖水的温度和电导率剖面进行了观测.结果表明,尽管所测盐湖宽深比大于90,还是存在温跃层.温跃层的矿化度(TDS)为60~160 g/L,靠近湖底的水体存在TDS低值异常区,形成化跃层,推测为地下淡水集中排泄所致.这种湖底泉在其它较浅的盐湖水体中也存在,说明深、浅层地下水对盐湖水分及盐分都有贡献.温跃层水温随深度的变化近似符合静止水体的热传导规律,并没有受到地下水排泄热量的显著影响.研究区盐湖跃层的季节性变化还有待进一步研究.;A number of salt lakes exist in the Badain Jaran Desert that located in the Alxa Plateau, China. To reveal the stratification characteristics of salt lake water and the impacts of groundwater to the lakes, a survey of the depth-dependent temperature …

Analyzing Water Consumption in Middle Reaches of Heihe River Based on Groundwater-Land Surface Coupling Model

HU Xiaonong

Water consumption analysis can directly reveal the essence of water use.In the basin scale,the evapotranspiration is the main body of water consumption.In this paper,a typical land surface model is coupled with a groundwater mode base on their respective advantages,and a groundwater-land surface …
