摘要
本文选取10项河流健康综合评价指标,引入信息熵理论确定指标权重,建立河流健康综合评价模型,运用综合健康指数法对沂河健康状况进行综合评价。结果表明:沂河目前综合健康指数为0.582,处于亚健康状态。评价结果基本切合实情,可见该方法是可靠的及适用的。评价结果也为沂河综合治理和科学管理提供了参考依据。
In the paper,10 river health comprehensive evaluation indicators are selected. Information entropy theory is introduced to determine index weight. Comprehensive evaluation model of river health is established. Comprehensive health index method is utilized for comprehensive evaluation on Yihe River health condition. The results show that current comprehensive health index of Yihe River is 0. 582,which is in the state of sub-health. The evaluation results are basically consistent with actual condition,and it is obvious that the method is reliable and applicable. The evaluation results also provide reference basis for Yihe River comprehensive control and scientific management.
