Based on the second national land survey data of Yunnan Province,it is analyzed on difference of land structure in 4 city,42 counties of Yunnan central urban agglomeration area based on a variety of quantitative geography model and information entropy method.The results showed that:(1)land structure of in the study area showed the difference spatial pattern of the Middle and the Eastern high,lower in Western;(2)city level and county-level land degree of centralization was not quite;(3) woodland,rablae land and grassland had obvious location significance,water and other land in general not significant;(4) the land-degree was higher,and the Middle and the Eastern higher the Western over all;(5) it was concluded that there was a relationship between the information entropy of land and the land diversity,which was not closely related the gross domestic product(GDP).%为分析滇中城市群土地利用空间结构差异性,以云南省第二次土地调查数据及其他社会经济数据为基础,综合运用多种计量地理模型和信息熵方法,对滇中城市群4个(州)市、42个县区土地利用结构的地域差异进行分析.研究表明,研究区土地利用多样化呈现中、东部高,西部低的空间格局差异;州市级和县区级的土地利用集中化程度相差都不大;林地、耕地和草地具有显著的区位意义,建设用地具有区位意义的区域集中在城镇化率高的地区,水域和其他土地区位意义不显著;土地利用程度较高,总体上中、东部要高于西部;土地利用信息熵与土地利用多样化具有一定关系,但不密切,与GDP并无紧密关系.
