摘　　要：利用遥感和GIS技术方法,对哈巴雪山2000—2010年TM影像进行人工目视解译得到研究区域的生态系统分类数据,并对研究区生态系统格局时空变化特征进行分析。结果表明:1研究区生态系统的格局变化主要集中在2000—2005年,而2005—2010年变化剧烈程度减缓,生态类型的变化主要集中在人为活动最为集中的金沙江流域的河谷区域;2生态格局分布的总体变化特征是:农地转化为居住用地、冰川/永久积雪和河流湖泊转化为草地或林地。人为因素对森林生态系统环境保护产生了积极影响,而对农业生态系统稳定性造成了一定干扰。Using remote sensing and GIS technology,the ecosystem classification data of Haba Snow Mountain of the 2000—2010 TM images is obtained by interpreting. And the characteristics of spatial and temporal changes of ecological system in the study area are analyzed. The result shows that： 1The areas of ecological system pattern change is mainly concentrated in 2000—2005,and the degree of change 2005—2010 is slow down. The changes of ecological types are mainly concentrated in the areas of the most concentrated human activities in the valley of the Jinsha River Basin; 2The overall changes of ecological pattern distribution are that： The agricultural land are converted into residential land,and glacier and permanent snow and rivers and lakes are converted into grassland or woodland. Human factors have a positive impact on the environmental protection of forest ecosystems,but the stability of the agricultural ecosystem has been disturbed.
