村镇生态护岸绿色基础设施综合体的构建——以安徽宣城南漪湖环湖地区为例

南漪湖环湖地区受到周边农业生产、圩区水产养殖及上游流域水量变化的影响,出现了水质污染、洪涝灾害、水土流失、水域及陆地生态系统之间缺乏良性互动、绿色基础设施功能单一等生态问题。鉴于生态护岸自身特征及其综合效益,文中认为可以通过构建生态护岸绿色基础设施综合体来解决南漪湖环湖地区的多种生态问题,在南漪湖现状分析研究的基础上提出了具有针对性的生态护岸类型和生态技术选择,并选取了较为典型的4个生态空间进行了生态护岸绿色基础设施综合体模式的构建,为生态护岸绿色基础设施综合体在我国风景园林建设中的应用提供了一种思路。

Green Infrastructure Complex Construction along Ecological Water Frontier in Rural Area:A Case Study of Nanyi Lake Area of Xuancheng,Anhui

Impacted by agricultural production, aquaculture development and the variation of water flow in upstream watershed, the loop area of Nanyi Lake suffers from a series of ecological problems such as water pollution, flood disaster, soil and water loss, lack of virtuous interaction between water and land ecosystems, unitary functions of green infrastructure. In view of characteristics and comprehensive benefits of ecological water frontier, the paper argued that the various eco-problems could be solved by constructing green infrastructure complex along ecological water frontier. Based on the study of Nanyi Lake's status, this paper provided targeted technological options as well as eco-waterfrontier types and selected four typical ecological spaces to construct green infrastructure complex, which would provide a new way to apply the green infrastructure complex along ecological water frontier to landscape architecture in China.
