基于景观格局指数的乡村生态规划方法

Landscape Layout Index Based Rural Ecological Planning Method

景观生态学的尺度理论和景观格局指数方法是研究乡村生态环境保护及村庄规划建设的有效技术方法,而按照尺度理论,村域尺度是乡村生态规划、土地利用管理和村庄建设控制的关键尺度。郑州市西南部生态带区域内的村庄规划通过分析景观指数的内涵与特征,选择景观形状指数(LSI)、斑块密度指数(PD)和边界密度指数(ED)实施乡村生态格局优化的预案研究,并提出可作为该地区乡村规划编制、方案评价和建设管理依据的景观格局指数的优化值。结果显示,景观生态学的尺度理论和景观格局指数方法对于保护乡村生态格局并适应村庄发展建设需求具有积极有效的作用。
