摘要

应用GIS

RS技术与景观格局分析软件FRAGSTATS研究了2001年黄河流域青海片土地利用和青海片内景观格局的空间分布

并根据构建的景观弹性度指数分析了研究区域的景观生态系统稳定性。结果表明

黄河流域青海片总体上以低覆盖和高中覆盖草地为主

景观不规则

较为复杂且不稳定

但无明显破碎化现象。片内黄河源头区域景观多样性和弹性度相对较低;片内黄河干流区域景观多样性、均匀度和景观弹性度相对较高。西宁市景观破碎度较高而景观弹性度较低

受人为干扰较强。

Abstract

Landuses and spatial landscape patterns of Qinghai Province in the Yellow River Basin in the year of 2001 are analyzed based on the technology of GIS and RS and using software of FRAGSTAT.An index of landscape resilience is further proposed to analyze the stability of landscape ecosy stem in the studied region.Results obtained show that the studied region is mainly covered with grassland

and it's landscape is complex and unstable

but has no obvious fragmentation.The diversity and landscape resilience indices of the headwaters of the Yellow River are lower than those of other counties

w hereas the diversity

equality and landscape resilience indices of the main stream of the Yellow River are higher than those of other counties in the studied region.In addition

the fragmentation of Xi' ning City is higher

whereas the landscape resilience index is lower than that of other counties in the studied regions

indicating that the Xining City meets with relative higher human disturbance than others.
