BILATERAL CHANGE DYNAMIC DEGREE MODEL FOR LAND USE AND ITS APPLICATION TO THE LAND USE STUDY OF IN SUBURBAN AREAS OF WUHAN

Abstract

Land use dynamic index is one of main models for depicting the change rate of land use types. When it depicts the change rate of the single land use type, it uses the net value of the area change of the single land use type. In fact, the net change results from bilateral dynamic change of the land use type. The change rate of land use use shown by the singe type land use dynamic degree thus calculated has already offset part of the bilateral change. On such a basis, a bilateral change dynamic degree model is put forward in this paper. In addition, the advantages of the model in expressing more land use information are also dealt with on the basis of investigation into the Jiangxia District of Wuhan City.
