零通量面法在沈阳地区地下水资源评价中的应用

The Application of Zero Flux plane Method in Groundwater Resources Evaluation in Shenyang Area

降水对地下水的入渗补给和大气蒸发作用下地下水的消耗是地下水资源的重要组成部分。降水入渗和地下水蒸发这两种作用均是通过包气带进行的。从包气带着手，运用零通量法确定这些量已在实际中得到应用。以沈阳地区为例，针对该区集中频繁降水与蒸发排泄交替进行导致零通量紊乱易变的特点，在对有关问题深入探讨的基础上，对浅层潜水入渗补给量（包括蒸发量）和非饱和渗透系数进行了计算。

The recharge of rainfall to groundwater and groundwater evaporation are important parts of groundwater resource.Both infiltrating and evaporating take place in vadose zone. The zero flux plane method(ZFP) has been used to calculate them recently. Taking example of Shenyang area,where concentrated rainfall and evaporating happen frequently in turn to lead to irregular and mobile zero flux plane, this paper analyzed some problems concerned,and then successfully calculated the recharge to groundwater(including evaporation) and unsaturated hydraulic conductivity.
