摘要
运用区位熵分解模型和空间洛伦茨曲线从土地利用类型变化方向、变化速率和变化态势3方面分析武汉市及其各城区2009-2013年土地利用结构的时序演变特征及空间分布差异。结果表明:(1)在变化方向上,除园地和其他土地外,其余各城区土地利用类型面积变化方向与全市总体趋同。(2)在变化速率上,各城区草地面积变化速率大于、小于或等于全市速率。其余各地类变化速率只有高于或低于全市平均水平两种情况。(3)在变化态势上,各地类熵值或下降或上升,空间洛伦茨曲线表现出明显的"三近五远"特征。
Taking Wuhan city as an example, The paper explored the change direction, velocity and tendency of land use to analyze the difference in spatial distribution and temporal evolution characteristics of land use structure across Wuhan from 2009 to 2013 by adopting Location Entropy Decomposition Model and Spatial Lorenz Curve. The result indicated that： ① From the perspective of change direction, in addition to the garden land and other land, the change direction of rest land use type were all coincident with those of the whole city. ②Contrasting to only two kinds of circumstances （higher or lower） consist in the other 7 land uses. change velocity of all pastureland showed higher, lower than or equal to average level of the whole city. ③From the view of land use change tendency, a variety of entropy values were fall or rise, beside spatial lorenz curve can be showed the characteristics of ＂three nearly and five far＂ obviously
