| 摘 要： | 本文利用1987、1997和2007年遥感数据，结合野外调查，以玉树藏族自治州为例，研究20年来景观空间格局的时空变化特征。结果表明，研究区草地景观面积减少，农田和荒地增加；草地斑块的分布越来越分散，斑块面积减小。草地和森林植被是玉树藏族自治州主要的植物资源景观，草地的连通性比较高；人为干扰和气候的变化是研究区景观时空变化的主要原因。研究结果为该区域生态保护对策的制定和环境的可持续发展管理提供了理论依据和技术的指导。

| Abstract: | Yushu Tibetan Autonomous Prefecture,an area located in the Qinghai-Tibet Plateau,is an area very sensitive to global climate change.Due to impacts from climate change and human disturbances,grassland vegetation in the area has been degraded and desertification has been expanding.Ecosystems in the area are very sensitive and fragile and ecological problems have become increasingly serious in the area,resulting in an adverse effect on the local socio-economic development and environment of Qinghai province.Us... |
