摘要:
将GIS和景观生态学的数量分析方法相结合，运用Arcinfo和Fragstats软件，分析了1986~2000年间，嘉陵江中下游地区的土地利用/覆盖和景观格局的变化，结果表明：在此期间，除林地和建设用地增加外，其它土地利用类型面积均有所减少，其中耕地和草地减少的幅度比较大；通过对该区斑块类型级别指标的分析，得出耕地的离散度加大，斑块形状更加不规则，复杂性增大；林地的斑块数增多，破碎度增大；而草地的破碎度下降，斑块数减少；通过对景观级别指标的分析，得出整个区域景观结构日趋破碎，复杂性和变异性都在增加。
Abstract:
The changes of land use/cover and landscape from the year 1986 to 2000 was analyzed with the integrated technology of ecological quantity analytical method based on GIS through Arcinfo and Fragstats. The result indicated that all land use types reduced to some extent except forestland and construction land, but the cultivated land and grassland had reduced rapidly. The analysis on the index of patch showed that isolation index of the cultivated land strengthened and the shapes of cultivated land were more irregular, which caused its complexity increased; the number of spots of the forestland increased, so did the fragmental degree; but the fragmental degree and the number of spots of the grassland both decreased. The analysis on index of landscape showed that the landscape was becoming more fragmental, complex and variable.
