昆明市乌龙古渔村片区海绵系统评价及功能分区研究

Study on Sponge System Evaluation and Functional Zoning in Wulong Ancient Fishing Village Area of Kunming

以昆明市乌龙古渔村片区为研究地,提取遥感影像图,借鉴生态适宜性评价方法选取相关的因子,采用AHP层次分析法对场地的生态海绵因子进行了评价分析,并利用ArcGIS进行多因子加权叠加,得到了场地的海绵性能功能分区图,根据分析结果将研究地划分为:生态建设区、生态恢复区、生态保护区3个部分;针对不同功能分区的特点结合场地现状提出了相应的雨水利用措施。通过对场地建筑区、七星山、滇池湿地及山林、梯田、农田等不同地区进行雨水处理和保护规划形成完整生态海绵体系,保护了滇池的生态安全及全局景观环境,协调了村落与周围环境的关系。

Taking the area of Wulong ancient fishing village in Kunming as the research site,Analytic hierarchy process(AHP)is used to evaluate and analyze the ecological sponge factors of the site.ArcGIS is used to carry out multi factor weighted super position.The sponge performance function zoning map of the site is obtained.According to the analysis results,the study area can be divided into three parts:ecological construction area,ecological restoration area and ecological protection area;According to the characteristics of different functional zones and the current situation of the site,the corresponding rainwater utilization measures are put forward.Through rainwater treatment and protection planning for the construction areas,Qixing mountain,Dianchi Lake wetland,mountain forest,terrace,farmland and other different areas,a complete ecological sponge system is formed to protect the ecological safety and overall landscape environment of Dianchi Lake,and coordinate the relationship between the village and the surrounding environment.
