| 摘 要： | 土地利用动态度是描述单一地类动态变化时采用的模型。事实上 ,土地利用数量净变化是土地利用双向变化的结果。为此 ,作者提出双向动态度模型 ,并以武汉市江夏区为例 ,探讨了结合土地利用动态度使用双向模型的优越性。

| 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. |
