In 2000,the area below 400 meters was also watershed,mining sites and settlements,the proportion of both unutilized land below 400 meters and woodland between 400 meters and 800 meters raised a little,it showed that most woodland transform into the other types of land use in low altitude area,however,most unutilized land and the other types of land use transform into woodland in low and mediad altitude area,and the changes in woodland had metastatic trends in low and middle altitude area in the years from 1988 to 2000.The area proportion between 400 meters and 800 meters raised a lot in mining sites and settlements,the total distributed area on woodland had a trend of rising,while the distribution in pasture had a trend of decreasing.

在2000年，400m区域以下依然是水域和居民点及工矿用地，未利用地比例在400m以下有所上升而林地比例在400m～800m有所上升，表明在1994年至2000年间，低海拔地区许多林地转化为其他土地利用类型，而在中低海拔地区大量的未利用地和其他土地利用类型转化为林地，林地的变化有向中低海拔转移的趋势。2006年居民点及工矿用地在400m至800m区域面积比例增加，林地类型分布区域整体呈上升的趋势，草地分布区域呈下降的趋势。
