摘要 文章根据城市生态文明建设和绿色发展理念的要求,结合绩溪县的相关规划,从连接性、渗透性和均衡性三个方面构建了绩溪县规划区的生态网络,选取的参数包括生态阈值、平均分维数、边缘指数、廊道密度和斑块密度;在分析现状的基础上,针对以上三个方面,从宏观、中观和微观角度分别提出了构建策略,并将构建策略落实到空间上,优化相关参数,得到相应成果,完成规划区生态网络的构建研究。 In accordance with the requirements of urban ecological civilization construction and green development concept,combined with the relevant planning of Jixi county, the ecological network of Jixi county planning area was constructed from as-pects of connectivity, permeability and equilibrium. The selected parameters included ecological threshold, average fractal dimen-sion, edge index, corridor density and patch density. Based on the analysis of the current situation, this paper proposes the con-struction strategy from the macroscopic, mesoscopic and microscopic perspectives for the three aspects above, and then implements the construction strategy spatially, optimizes the relevant parameters, obtains the corresponding results, and completes the research on the construction of the ecological network of the planning area.
