摘要
以丽江至香格里拉铁路为例,选取了随土地利用分类系统变化的可预测性强的景观格局指数,分别反映景观面积、密度、邻近度、多样性和聚散性,对研究区生态系统结构及铁路建设对其产生的影响进行分析。结果表明,选取的景观格局指数能够反映研究区生态系统的结构状况及其变化,能够保证生态环境影响评价的科学性。
The landscape indices of strong predictability were selected to reflecting the area and density and proximity and diversity of the landscape to assess the environmental impacts from railway construction. The results show that the indices selected can reveal the structure and change of the target area, which can ensure the scientificity of ecological environmental impact assessment.
