摘　　要：土地利用是全球环境变化研究的热点问题之一,本文在对米易县土地利用变化分析的过程中,引入景观格局分析方法开展土地利用动态变化的研究。采用ERDAS软件对1988年和2003年的两期遥感数据进行处理,结合Fragstats3.3景观格局分析软件,分别在斑块水平指数和景观水平指数上对研究区土地利用景观类型进行动态分析,揭示其变化原因和内在规律,为研究区生态治理提供数据支撑。并对景观的规划与管理、资源的有效利用和生物多样性保护具有重要意义。Land use is a hot issue of global environmental change, and this thesis introduced the approach of landscape pattern analysis to study land use change, during the process of analysis on land use changes of Miyi County in Panzhihua. The study used ERDAS to process the digital images of remote sensing of the study area in 1988 and 2003. And Fragstats3.3, a software analysis of landscape pattern index, was also used to analysis the land use types by the landscape indexes both at patch level and landscape level. The thesis revealed the reasons for the dy- namic changes and its internal rules. It can provide the data supporting for the ecological management. Additionally, the study is of great significance on the landscape planning and management, the effective use of resources and the protection of biodiversitv.
