韩仓河流域水生态韧性修复适宜性评价

Evaluation on Applicability of Water Ecological Resilience Restoration of Hancang Basin

文章从城市生态系统的核心水生态系统出发,提出一种水生态韧性修复适宜性评价方法,用以指导城市规划及修复城市生态系统健康。以济南市韩仓河流域为例,使用生态因子组合法构建评价方法框架,并以层次分析法和ArcGIS技术分别进行权重分析和因子叠加。韩仓河流域的水生态韧性修复适宜度评价结果分为非常适宜、较适宜、适宜、较不适宜和不适宜5类,其面积占比分别为5.61%、23.82%、25.82%、29%和15.75%。

Based on the water ecosystem,the core of the urban ecosystem,an applicability evaluation method of the water ecosystem resilience restoration is proposed in this paper to guide the urban planning and the restoration of the urban ecosystem health.Taking Hancang basin in Jinan City as an example,the framework of the evaluation method is constructed by the combined ecological factors.The weight analysis and the factor superposition are performed by using AHP and ArcGIS technology,respectively.The evaluation results of the applicability of the water ecological resilience restoration in Hancang basin can be divided into five categories,which are most suitable,more suitable,suitable,less suitable and not suitable,with the area proportion of 5.61%,23.82%,25.82%,29% and 15.75%,respectively.
