Fractal Analysis of Land Use Change in Three Gorges Reservoir Area during 1995-2015
摘要
Abstract
From space morphology angle,based on the fractal theory,using fractal dimension model the fractal characteristic of land use change were analyzed in Three Gorges Reservoir Area from 1995 to 2015.It indicated that the fractal dimension of each land use class was less than the critical value of 1.5.The average value of fractal dimension dropped from 1.162 1 to 1.126 6,so the spatial morphology and structure tended to be more regular and stable from 1995 to 2015.The fractal dimension of cultivated land gradually rose from 1995 to 2015,opposite to that for forestry land,water area and grass land.The spatial morphology and structure of cultivatated land tended to be more irregular and unstable,opposite to that for forestry land,water area and grass land.Because the spatial structure stability of cultivatated land declined,it was critical to deal with the contradiction between development and cultivatated land management in the future.The fractal dimension of construction land and unutilized land rose and then reduced,and rising amplitude is bigger.The spatial morphology and structure of construction land and unutilized land tended to more regular and stable.关键词
