- 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.
