摘要
大荔县是关中盆地的农业大县,也是陕西经济最活跃的地区之一,而水资源不足成为经济进一步发展的制约因素。以地质和水文地质条件为依据,从影响地下水形成的诸因素出发,对大荔县地下水资源进行定量评价。结果表明:大荔县地下水资源总量为3.08×108m3/a,其中地下水质安全区水资源总量为1.1×108m3/a,仅占水资源总量的35.6%;通过地下水资源的对比分析,结合水资源开发利用空间分布特征,对区内地下水资源进行解析,得出现状水利工程条件下大荔县水资源开发利用不合理性的结论,并提出水资源可持续利用对策。
Dali County is the most economically prosperous region in Guanzhong basin,but the further growth of it＇s economy is constrained because of the shortage of water resources. Based on geological and hydro geological conditions,we evaluated and analyzed groundwater resources from the point of factors that affect the formation of groundwater. The results showed that total resources of groundwater is 3.08×108m3/a,hereinto drinkable resources of groundwater is 1.1×108m3/a,and this is only 35.6% of total resources of groundwater. Combined with parallel analysis or dimensional exploitation and using characteristic,we evaluated and analyzed groundwater resources. The result indicated that the exploitation and using model of water resources are out of place.
