摘要
为了合理开发利用地下水资源,为缺水地区农业的发展提供供水保障,开展地下水环境容量研究是非常必要的。在分析地下水环境容量内涵的基础上,对地下水环境容量进行重新定义,并提出综合指标环境容量的概念,在此基础上建立了综合指标体系QVLTE和综合评价指数R。通过QVLTE指标体系在静升盆地浅层地下水环境容量定性评价中的应用,得出地下水水质和地下水水量对地下水环境容量影响较大,地表植被和地下水温相对较小,这与实际吻合较好,印证了QVLTE指标体系具有一定的实际应用价值。研究成果可为地下水环境容量进一步的定性研究提供参考,对缺水地区地下水的保护、农业的健康发展具有重要的现实意义。
In order to utilize the groundwater resources in a scientific and rational way,and provide water resources guarantee for water-deficient area,it was very necessary to carry out the research of groundwater environmental capacity.On the basis of analyzing connotation of groundwater environmental capacity,the concept of groundwater environmental capacity was defined,and the comprehensive environmental capacity was put forward.The QVLTE index system and R index were established by comparing current indexs of the groundwater environmental capacity and the concept of comprehensive environmental capacity.Groundwater quality and water volume were the main impact factors by applying the system of QVLTE to Jingsheng basin.The results closely meet the actual situation.Research results would provide basis for the conservation of groundwater and the healthy development of agriculture.
