河北太行山区不同坡度土地利用类型格局的动态变化分析

Analysis of Landscape Pattern's Change of Different Gradient of Taihang Mountain Area in Hebei Province

运用景观格局指数方法,分析河北太行山区1987～2000年13年间不同坡度各景观类型(耕地、林地、草地、建设用地、水域及未利用土地)的变化特征,并简要分析造成变化的驱动因素.研究结果发现研究区域的耕地面积总体呈下降趋势;林地和草地在坡度较大的范围内急剧减少;建设用地因经济发展的制约,呈下降趋势,但土地利用总体面积较小,变化情况不明显.

Apply the method of landscape ihdex analyses the change of the different gradient landscape and derive factor between 1987 and 2000.The result shows us that： the area of the plantation is downtrend;the areas of the forest and grass is rapidly reduced at the biggish gradient.Although the constructive land is drop because of the restriction of the economy＇s development,the diversification is not obvious.
