| Abstract: |
| 【Objective】The purpose of this paper is to study the variation trend of groundwater level in usu city under the influence of human activities, the influence of various factors on the groundwater level in this area was analyzed, which was of great significance to the development and utilization of water resources.【Method】Through the groundwater survey of Usu city in September 2018, the groundwater flow field and buried depth were analyzed by Mapgis, and we stated the variational factors such as agricultural acreage, amount of groundwater mining, water-saving irrigation area, surface water diversion, total irrigation area and the number of wells from 2008 to 2017, the evolution trend of groundwater level was illuminated, the grey correlation method was used to evaluate the degree of the factors associated with the burial depth of the underground water level.【Result】The groundwater flows from the south to the north, then to the west into Abigail Lake. Under the influence of human activities, the groundwater level was decreasing as a whole. The gray correlation between surface water diversion and groundwater exploitation was greater than 0.6.【Conclusion】The main driving forces affecting the evolution of groundwater level are surface water diversion and groundwater exploitation in this area. After the implementation of the total water control scheme, the water level of usu city has risen to some extent. It is still necessary to master the dynamic change of groundwater level in the process of groundwater development and utilization. |
