Abstract:
The evaluation index system for the Xing fu river is constructed consisting of 26 indicato rs including the natural attributes of the river basin, social and economic attributes, and the harmo nio us relationship between people and water. T he evaluation result of the Xing furiver is expressed by the Xing fu river index. According to the demand hierarchy theory , the Xingfu river index is divided into the basic demand level, the development demand level, and the harmonious demand level. Taking the Yellow River Basin as an example, the fuzzy comprehensive evaluation method is used to evaluate the Xingfu river index of the Yellow River. The results show that the Xingfu river index in the upstream and middle of the Yellow River reaches the intermediate level of demand and the downstream Xingfu river index is at the basic level of demand. The construction of the evaluation index system of the Xingfu river prov ides a reference for the scientific evaluation of the Xingfu river and enriches the theoret ical research of the Xingfu river.
