摘要 '三生空间'功能优化是进行国土空间优化的重要基础,对生态文明建设具有重要意义。以云南省第二次土地调查数据为基础,构建滇中城市群'三生空间'功能分类体系。基于不同的行政尺度,采用不同的计量模型和GIS空间分析方法,对滇中城市的4个州市和42个县区的'三生空间'功能格局分布特征进行了多尺度分析。结果表明:(1)在市域尺度上,滇中城市的'三生空间'功能结构呈现出多样化和信息熵空间分布中、东部高西部低的现状;集中化程度空间分布整体较低且各地相差不大;优势度整体较高;各州市区位特征不显著。(2)在县域尺度上,滇中城市的'三生空间'功能结构呈现出多样化和信息熵空间分布东部高,西部低的现状;集中化程度除昆明市主城区外其他各地分布趋近;优势度呈中间低两边高的分布现状。(3)通过县域与市域尺度的分析对比,揭示了各尺度间'三生空间'功能分布格局的相互关系,实现各尺度间的良性约束和优化配置,为城市群的国土空间功能优化提供了必要的依据。 The optimization of the ecological-production-living space function is an important basis for the optimization of land space and is of great significance to the construction of ecological civilization.Based on the second land survey data of Yunnan Province,the functional classification system of ecological-production-living spaces of the urban agglomeration area of central Yunnan was constructed.Based on different administrative scales,different econometric models and GIS spatial analysis methods were used to analyze the distribution characteristics of the ecological-production-living space functional patterns in four cities and 42 counties in central Yunnan.The results show that:(1)on the municipal scale,the functional structure of the ecological-production-living space in the urban area of the urban agglomeration of central Yunnan presents the current situation of diversification and spatial distribution of information entropy in the east and high in the west;the spatial distribution of centralization is generally low and the differences are not significant;the overall degree of dominance is higher,the location characteristics of each city are not significant;(2)on the county scale,the functional structure of the ecological-production-living space in the urban area of the urban agglomeration area of central Yunnan presents high diversification and information entropy of spatial distribution in the east and the low one in the west;the degree of centralization tends to be similar in all areas except the main urban area of Kunming and the distribution of dominance degree is low in the middle area,and high in the fringe areas;(3)through the analysis and comparison of county and city scales,the relationship between the functional distribution patterns of the ecological-production-living between different scales is revealed,and the benign constraints and optimal allocation between the scales are realized,which provides the necessary basis for the optimization of territorial spatial functions of urban agglomerations.
