Abstract
River plays an important role in t he aquatic ecosyst em, and river health is an important indicator of social and economic development and ecological environment protection. Based on the analysis and calculat ion of the indexes of river ecological func-tion, including the habitat diversity index, river w ater quality index, river runoff index, forest coverage index, groundwater over-exploitation index, and river longitudinal continuity index, the weight of each index w as determined in considerat ion of the effects of each index in the overal evaluation, and each index was standardized to develop the assessment index system of river health. The system was applied to the Luanhe River Basin to evaluate it s ecological function based on the survey results of the basin, and the evaluation result was betw een normal and poor. T he evaluation method considers a number of factors affecting the ecological function of the river, so the evaluation results can reflect the actual ecological functions of the river and then provide references for the development and management of river.关键词
