基于YAAHP软件的河流健康诊断——以浑河流域沈抚段为例

River health diagnosis based on YAAHP software——A case study on Shenfu section in Hunhe River Basin

通过YAAHP软件对选取的浑河流域沈抚段上游与下游的河流进行诊断,确定浑河流域沈抚段的河流健康状况。通过实地调查和参考相关文献,采用层次分析法和模糊综合评价法相结合,确定健康诊断指标体系,并在YAAHP软件中进行建模研究。上游段友爱河获取较高的分数,为2.9438分,下游段杨官河只有2.0361分。上游河流健康状况要优于下游河流健康状况,但是流域内整体健康状况偏差。

In order to determine the river health conditions of Shenfu section in Hunhe River Basin,the YAAHP software was used to diagnose the upstream and downstream rivers.Through the field investigation and reference to relevant literature,the combination of AHP and fuzzy comprehensive evaluation method was used to determine the health diagnosis index system,and the modeling research was carried out in YAAHP software.The upstream section of You'ai River got a higher score of 2.9438 points,while the downstream section of Yang Guanhe only got 2.0361 points.Although the health condition of upstream river was better than the downstream river,the overall health of the river basin was in reverse condition.
