| Abstract: |
| Based on GIS and remote sensing imagines, the changes of land use/coverage and landscape pattern of Yuli County from 1995—2000 were analyzed. The results showed that the areas of farmland and residential land increased obviously while the areas of forest, grassland and unuesd land decreased. The analysis of landscape index showed that due to the disturbance of human activities, landscape fragmentation index increased while land diversity index decreased. The structure and function of ecosystem became increasingly simpler and weaker. The study also found that human activities, such as urbanization, population quality and mode of economic development were dominant factors for these changes, and the natural factors like precipitation, wind speed, soil texture and vegetation coverage are also driving factors. |
