利用灰色关联度确定灌溉取用地下水的方式

Way to determine groundwater using of irrigation by grey correlation degree

针对平原区灌溉方式以浅层和深层地下水为主,以华北平原河北省献县为例,利用灰色关联度分析,得到年降雨量和浅层、深层地下水埋深的关联系数,最终确定献县区域开采地下水以深层地下水为主。

Irrigation methods in plain areas are mainly with shallow water and deep groundwater in North China Plain. Taking Xian County of Hebei Province as an example, based on the gray relational analysis, correlation coefficient is gained between annual rainfall and shallow and deep buried depth of groundwater, which determines that groundwater exploitation of Xian County regional is mainly in deep aquifers.
