摘要

采用灰色关联度法和BP神经网络法计算各指标权重，然后用综合指数法分别对滹滏平原1984年和2000年地下水资源脆弱性进行了评价。2000年相对于1984年，地下水资源脆弱性分布特征发生了明显的变化，而且脆弱性级别升高。地下水资源脆弱性具有时变性，制定地下水合理利用模式时应当结合现状实际地下水资源脆弱性。

Abstract

This paper computed the weight of influence factors by gray pertinence method and BP network

and as- sessed shallow groundwater resource vulnerability in the Hufu Plain in 1984 and 2000 by the integrated method. The changes in vulnerability grade and its spatial characteristics in 2000 were significant compared with those in 1984.The advices to exploit properly groundwater should be based on current groundwater resource vulnerability because of its changes with time.
