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。
通過對包括生境多樣性指標、河流水質指標、河口徑流指標、森林覆蓋率指標、地下水超採率和河流縱嚮連續性指標等河流生態功能指標進行分析,攷慮各項指標在整體評價中的作用確定指標權重,併對各項評價指標進行標準化處理,建立瞭河流生態健康評價指標體繫。據此,利用灤河流域有關成果調查和資料,對灤河河流生態功能進行評價,評價結果介于一般與較差之間。該評價方法攷慮瞭多項影響河流生態功能的因素,因此評價結果能較好地反映河流生態功能,可為河流開髮和管理提供參攷依據。

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.
