Based on the landscape remote sensing mapping , buffer zone analysis and total variation index calculation of landscape structure for two neighbored buffer zones were used to divide the natural landscape and human impacted landscape in wolong natural reserve . the spatial distribution characteristics of human impacted landscape were also studied 在景观遥感制图的基础上，利用缓冲区分析和相邻缓冲区的景观结构总体变异系数方法对卧自然保护区进行了自然景观和人为影响景观的分割研究，并对人为影响景观的空间分布特征进行了分析。
