吐鲁番盆地平原区地下水控制性指标研究

为了解决吐鲁番盆地地下水水位变化引发的生态环境问题,本文基于吐鲁番盆地地下水补给、径流、排泄特征,利用pearson相关分析法和标准化系数分析了各因素对地下水位的影响特征,提出了吐鲁番盆地平原区地下水水量水位控制指标.结果 表明地下水开采量、田间灌溉入渗补给量和渠道渗漏补给量对地下水位的影响较大,并且确定了地下水开采量...

Research on control indexes of groundwater in the plain area of Turpan Basin

In order to solve the ecological and environmental problems caused by the changes of groundwater level in the Turpan Basin, this paper uses pearson correlation analysis method and standardized coefficient to analyze the characteristics of the influence of various factors on the groundwater level based on the characteristics of groundwater recharge, runoff, and discharge in the Turpan Basin, and proposes the Turpan Basin plain area groundwater quantity and level control index. The results show that the amount of groundwater abstraction, field irrigation infiltration replenishment and channel leakage replenishment have a greater impact on the groundwater level, and the groundwater abstraction volume index, the regional groundwater level annual decline rate index, and the depth of the typical monitoring well groundwater level have been determined. Indicators and water level control indicators of various townships in the plain area, Tuyugou, Xiaxiang and Pizhan Township are designated as key control areas, and groundwater level control and monitoring in this area should be strengthened. Through the establishment of dual control indicators for the quantity and level of groundwater, the problem of serious decline in groundwater level year by year has been effectively solved.
