%X 通过对包括生境多样性指标、河流水质指标、河口径流指标、森林覆盖率指标、地下水超采率和河流纵向连续性指标等河流生态功能指标进行分析，考虑各项指标在整体评价中的作用确定指标权重，并对各项评价指标进行标准化处理，建立了河流生态健康评价指标体系。据此，利用滦河流域有关成果调查和资料，对滦河河流生态功能进行评价，评价结果介于一般与较差之间。该评价方法考虑了多项影响河流生态功能的因素，因此评价结果能较好地反映河流生态功能，可为河流开发和管理提供参考依据。  River plays an important role in the aquatic ecosystem, and river health is an important indicator of social and economic development and ecological environment protection. Based on the analysis and calculation of the indexes of river ecological function, including the habitat diversity index, river water quality index, river runoff index, forest coverage index, groundwater overexploitation index, and river longitudinal continuity index, the weight of each index was determined in consideration of the effects of each index in the overall 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 its ecological function based on the survey results of the basin, and the evaluation result was between normal and poor. The 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.
