摘要
基于遥感图像,利用基质的比例,斑块数量和面积变化率,斑块密度变化率3个指标对祁连山东段山地景观稳定性进行了研究。研究结果表明:①草地是祁连山东段山地景观稳定性最高的组分,处于稳定状态。②中小尺寸的斑块稳定性最高。对景观生态规划和区域生态稳定有重要意义。
The security of Eastern Qilian Mountainous landscape was analyzed with percentage of matrix,changing rate of patch number and area,changing rate of patch density based on RS.The result showed that:① grassland which maintained in stability condition was the key composition in the stability of eastern Qilian Mountainous landscape;② patches with little area got the highest stability condition,and played important role in maintaining the landscape heterogeneity in eastern Qilian Mountainous landscape.
