摘要
Abstract
[Purpose] It aims to study the situation of ecological vulnerability of grassland in Yushu. [ Methods] Based on the field survey sampling spots on grassland of Yushu, interpretation has been conducted on grassland types on TM remote sensing image, and grassland degradation degree has been qualified. By using landscape indexes, ecological vulnerability analysis has been conducted on landscape types of seven natural grasslands. [ Result] The comprehensive index of ecological vulnerability of Yushu grassland is low, and moderately vulnerable area and above have taken up 99. 91% of the total area.
