摘  要:
根据2009~2013年芒市土地利用变更调查数据,运用土地利用动态度、土地利用程度综合指数、信息熵、均衡度和优势度、变化强度等模型,对芒市土地利用的数量、程度、结构、强度等的变化情况进行计算,多层面分析不同时段各类土地利用/土地覆被类型的动态变化情况。结果表明,在数量变化方面,芒市农用地和建设用地的变化幅度和变化速率都比较快;在程度变化方面,芒市土地利用程度综合指数处于中等偏上水平,且基本保持稳定发展;在结构变化方面,芒市土地有序度高于全国平均水平,土地利用偏向于集中开发;在变化贡献率和变化强度方面,芒市耕地、林地、园地和城镇村及工矿用地依然处于核心地位,主导着全区土地利用变化的趋势。

摘  要:
According to the change survey data of land use in Mangshi City from 2009 to 2013,changes of land use quantity,degree,structure and intensity were calculated by using land use dynamic index,comprehensive index of land use degree,information entropy,balance degree,dominance degree,change intensity and so on. Dynamic change of land use/land cover type was analyzed in different time periods from multi-dimensions. Results showed that in the aspect of quantitative change,amplitude and speed of variation were relatively high in agricultural land and construction land of Mangshi City. In the aspect of degree change,comprehensive index of land use degree was above the middle level,and basically maintained stable development. In the aspect of structural change,land order degree of Mangshi City was higher than the national average level,and land use tended to centralized development. In the aspect of change contribution rate and change intensity,the cultivated land,forest land,garden plot,urban village and industrial and mining land were still at core status,which dominated the land change trend.
