阿克苏地区温宿县地下水超采区评价

Evaluation of groundwater over-exploitation area in Wensu County,Aksu Region

为加强地下水管理与保护、加快推进地下水超采区治理,以阿克苏地区温宿县地下水为例,将评价区划分为库托河灌区、柯柯亚河灌区和台兰河灌区。对地下水超采区进行了划分,选用了160个站点的资料,以其中10组为例,计算了评价期水位动态变化速率,绘制了水位变化速率分布,并采用3种方法初步划分的超采区,并通过相互叠加的方法对初步划分的超采区进行了复核,宿县地下水超采区总面积1633.71 km^(2),其中一般超采区4处,总面积1236.11 km^(2)。严重超采区3处,严重超采区面积397.61 km^(2)。对地下水禁采区与限采区进行了划分,共划分禁采区2个,分别是佳木镇种羊场一带和古勒阿瓦提东部四大队一带,共计85.84 km^(2),除禁采区外的区域全部划为限采区,共计1547.87 km^(2)。并结合地方实际,提出了具有针对性的超采区管理建议。

In order to strengthen the management and protection of groundwater and speed up the governance of groundwater overexploitation areas,taking the groundwater in Wensu County,Aksu Prefecture as an example,the evaluation area was divided into Kutuo River Irrigation Area,Kekeya River Irrigation Area and Tailan River Irrigation Area.The groundwater over-exploitation area was divided,and the data of 160 sites were selected.Taking 10 groups as an example,the dynamic change rate of the water level during the evaluation period was calculated,and the distribution of the rate of water level change was drawn.The preliminarily divided over-exploitation areas were reviewed by the method of superimposing each other.The total area of groundwater over-exploitation areas in the Suxian County was 1633.71 km^(2),including 4 general over-exploitation areas with a total area of 1236.11 km^(2).There were 3 serious over-exploitation areas,with an area of 397.61 km^(2).The groundwater mining prohibited area and restricted mining area were divided into 2 prohibited mining areas,namely,the area of Jiamu Town Sheep Farm and the area of 4th Brigade in the east of Gule Awati,with a total of 85.84 km^(2).The areas outside the area were all designated as restricted mining areas,totaling 1547.87 km^(2).And combined with the local reality,put forward a targeted over-mining area management suggestions.
