河流生态修复评价方法探讨

目前,有关河流生态修复评价指标体系研究中缺乏对经济可行性因素的考虑。在分析河流生态修复评价和相关经济可行性研究成果的基础上,通过识别河流生态环境的自然因素和社会因素,探讨了河流周边社会经济因素对河流生态系统修复产生的影响,并从修复必要性评价和经济可行性评价两方面着手构建了适用于河流生态修复评价的指标体系。采用层次分析法对河流生态修复评价指标赋予权重,建立了模糊综合评价模型,为河流生态修复评价研究提供了一种新的方法。最后,以河南省贾鲁河郑州段和周口段为例开展实际应用研究,结果证明本评价方法可行。

Discussion on Evaluation Method of River Ecological Restoration

The current evaluation index system of river ecological restoration lacks the consideration of economic feasibility. Based on the With analysis of research achievements on river ecological restoration assessment and economic feasibility analysis, through identification ofthe river ecological environment natural factors and social factors of river ecological environment were identified, as the evaluation indicator system researches of river ecological restoration now lacks of considering economy feasibility factors surrounding river, this paper mainly discusses and studies the impacts resulting from of socio-economic factors surrounding the river on river ecological system restoration were discussed, and and sets an evaluation indicator index system for river ecological restoration on the basis of from two aspects ofabout restoration necessity and economic feasibility. Adopting The analytic hierarchy process was used to assigngive the indicator index weight and to develop calculating indicator value with a fuzzy comprehensive evaluation model, which provided a new method for river ecological restoration assessment. in many related literatures. The evaluation index system was applied to Making application on the Zhengzhou and Zhoukou sections of Jialu River, and the evaluation results suggested that the method is feasible.
