西部六省居住用地与工业用地的集聚变化态势研究

Study on the Aggregation and Change of Residential and Industrial Land in Six Western Provinces

采用空间自相关和空间回归模型等空间计量方法,选取中国西部6省86个县(市)为单元对2000—2012年居住用地与工业用地时空变化的空间格局进行分析并对集聚变化原因进行测算。结果表明,(1)2000—2012年西部6省的居住用地Moran’s I指数从0.22上升为0.40,空间集聚正在逐步增强;工业用地则从0.18上升为0.23,相对居住用地集聚现象偏弱。(2)从城市空间格局考察居住用地与工业用地集聚变化态势,HH类型及LL类型的变化最为显著,多出现在内蒙古。(3)城市建设用地面积、国民生产总值、第三产业占GDP的比重及公共用地面积对居住用地在空间上集聚影响最为显著;人均国民收入、工业产值、交通用地面积及人口数量对工业用地在空间上集聚影响最为显著。

Spatial autocorrelation and spatial regression models were used to analyze the spatial and temporal changes of residential and industrial land from 2000 to 2012 of 86 counties and cities in 6 western provinces of China. Results showed that,（1） The Moran＇s I index of residential land in the six western provinces changed from 0.22 to 0.40 in 2000-2012,the spatial agglomeration gradually increased, the industrial land was increased from 0.179 to 0.230,and the relative residential land was weakly clustered.（2）From the urban spatial analysis of residential land and industrial agglomeration trend,HH type and LL type had the most significant change, mostly in the province of Inner Mongolia.（3）The urban construction land area,gross national products,the proportion of tertiary industry to GDP and the public land area had the most significant impact on the spatial agglomeration of residential land. The per capita national income,industrial output value, traffic land area and population size had the most impact of significant spatial agglomeration on residential land.
