| 摘 要： | 介绍了基于层次决策分析的河流生态功能综合评价方法,提出了在河流水文评估、物理化学评估、生物栖息地质量评估和生物评估4个单项评估的基础上,构建以河流生态功能综合指数为目标、4个单项因子为准则、5个等级标度为决策标准的层次递阶模型,应用模型进行了河流综合评价的两种情景分析。

| Abstract: | The comprehensive assessment method for ecological functions of rivers based on analytic hierarchy process(AHP) was discussed.With river ecological function as objective and five grades as decision criterion,a hierarchy model was established based on individual evaluations on four factors,i.e.,hydrology,physical chemistry,habitat and biology.Two cases about comprehensive assessment of rivers were studied by the model. |
