摘要
结合桓仁县1999年和2009年土地调查现状数据库矢量成果,借助ArcGIS和Fragstats分析软件,运用景观格局分析方法,从土地利用类型的景观特征角度,定量分析了土地利用变化情况。结果表明:①1999-2009年全县景观类型斑块数量总体呈现出增加的趋势;②景观类型斑块面积除园地、林地、交通运输用地和城镇村及工矿用地10年间增加外,其余类型景观面积均明显减少;③从平均形状指数与分维数来看,除园地、交通运输用地增加外,其余类型均有所降低;④从景观斑块形状破碎化指数和景观破碎度指数对比来看,各景观类型总体呈现斑块数趋于破碎,但斑块形状略显规则。
With the help of GIS and Fragstats and the basic theory and method of landscape pattern analysis, this paper gives a quantitative analysis of land use change in Huanren County in the period of 1999 to 2009 from the angle of landscape characteristic of land use type. The results indicate that ： （1）the number of landscape type patch assumed a general trend of increase between 1999 and 2009; （2） the areas of other landscape type patches were significantly decreased during the past 10 years, except for garden, woodland, transportation land and residential and industrial land ; （3） from the average shape index and the fractal dimension, other landscape types were reduced, excluding the increase of garden and transportation land; （4） in terms of landscape shape of patch fragmentation index and landscape patchiness index, the number of landscape type patch general tended to break, but the shape of patch tended to slightly rules.
