【摘要】：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。
[Abstract]:In order to analyze the difference of land use spatial structure of urban agglomeration in central Yunnan, based on the data of the second land survey and other social and economic data in Yunnan Province, a variety of econometric geographical models and information entropy methods are used synthetically. The regional differences of land use structure in 4 cities and 42 counties of urban agglomeration in central Yunnan were analyzed. The study shows that the spatial pattern difference of land use diversification in the study area is high in the east and low in the west, and the degree of land use centralization at the state level and the county level is not different. Woodland, cultivated land and grassland have significant regional significance, construction land with regional significance is concentrated in areas with high urbanization rate, water area and other land location significance is not significant; The degree of land use is relatively high, in general, the eastern part is higher than the west, and the land use information entropy has a certain relationship with land use diversification, but is not close, and has no close relationship with GDP.
