摘要
层次分析法定权近年应用较广，但也存在计算复杂、不易掌握、受人为主观影响较大、权重不稳定等问题。本文提出的改进ＡＨＰ法以地面水环境质量分级标准为依据建立三标度比较矩阵，计算水环境指标的权重，克服了上述不足。并把计算出的权重值应用到浦东新区水质的对比系数评价中，评价结果与实际情况较为吻合。
AHP has been applid extensively.but there are some limitations.The paper puts forward an adapted AHP metbod. Based on surface water environmental quality standard, it sets up comparative matrix scaled with 0-2,and calculates weights of indexes in water environment. The paper also,applies contrast coefficient method To water quality assessment in pudong New Area,and the results are objective and reasonable.‘
