Abstract: The evaluation of rural river ecological condition is the basis of rural river ecological management. According to the characteristics of rural rivers,the evaluation index system of rural river ecological conditions is constructed from six aspects:river function,river form,river environment,river ecology and landscape,river management and comprehensive evaluation. The integrated order relationship analysisentropy weight method obtains the combined weight of each index. An established fuzzy matter-element evaluation model is used to comprehensively evaluate the ecological status of rural rivers in Jiangsu Province. The results show that the ecological conditions of rural rivers in Jiangsu Province are generally good,but some rural rivers still have poor ecological conditions,and there are regional differences in the ecological conditions of rural rivers in Jiangsu Province. The evaluation results are basically consistent with the actual situation.
