摘要:
在RS和GIS支持下，通过解译山西吉县清水河流域1986年、2000年、2007年TM遥感影像，生成土地利用分类并进行流域植被景观制图，分析了植被景观结构特征及变化趋势，同时，在GIS系统支持下，建立了清水河流域植被景观元素转移矩阵。结果表明，流域的植被景观基质始终是荒草地和灌木，1986年流域植被景观要素面积大小排序为：草地>阔叶林>灌木>农田>针叶林>园地>居住用地，草地、灌木和阔叶林3类占到总面积的87%以上，草地是绝对优势景观要素，占到景观总面积的41.69%，且连片性较好，灌木斑块数最大，分布零散、破碎，2000年流域植被景观要素排序变为：草地>灌木>阔叶林>农田>针叶林>园地>居住用地，2007年流域植被景观要素面积排序为：灌木>阔叶林>草地>针叶林>农田>园地>居住用地；通过分析两个时段景观转移矩阵，表明20 a间灌木面积比例持续增加，且主要来源于草地。
Abstract:
With the help of RS and GIS, by interpreting the Landsat-TM images of Qingshuihe watershed in 1986, 2000, 2007, the information from Vegetation Landscape Mapping are used to analyze the spatial pattern change, then establish the transfer matrix of the Vegetation landscape to realize the dynamic change. The results show:the vegetation landscape matrix is always grassland and shrubs, grassland elements is the absolute superiority in 1986, accounted for 41.69% of the total area of landscape, in 1986 the vegetation landscape elements size listed in order is: grass>deciduous>shrub>crop>coniferous>orchard>residential land; in 2000, grass>shrub>deciduous>crop>coniferous>orchard>residential land; in 2007, shrub>deciduous>grass>coniferous>crop>orchard>residential land, the shrubs plaque become the first place, accounting for 35.97% of the total area, and was the superiority of vegetation landscape. Also the results from conversion matrix indicate that the grassland had changed to shrub continuously through 20 years.
