【摘要】：本文在探究"生产—生活—生态"三生空间理论内涵的基础上,分析了土地利用功能与土地利用类型的辩证关系,依据土地利用现状分类国家标准,建立了三生空间分类与评价体系,揭示了1990-2010年间中国三生空间的格局及其变化特征。结果表明:(1)生产空间主要分布在胡焕庸线东南侧的主要城市群及粮食主产区,其扩张区域主要分布于东北平原、新疆西北、宁夏、兰州—西宁、四川盆地、环渤海、长三角、厦漳泉、珠三角等地区,缩小区域主要分布在黄土高原、呼伦贝尔大草原、江汉平原、闽南丘陵等地区;(2)生活空间主要集中在全国主要城市及城市群,整体上呈现"东高西低、北高南低;大分散、小集聚"的空间格局,其扩张过程表现为环渤海、长三角、珠三角三大城市群的大规模、区域式扩张和各主要省会城市的小规模、点状式扩张。(3)生态空间主要分布在胡焕庸线西北侧,整体呈现"西高东低,南高北低"的空间格局;(4)工业化、城镇化是中国三生空间变化的基本动力,西北和东北地区的农田开垦、华北平原和三大城市群的城镇化建设、黄土高原的退耕还林等是导致三生空间区域差异的主要原因。本文可以为三生空间的分类规划和优化决策提供参考依据。
[Abstract]:On the basis of probing into the connotation of the space theory of "production, life and ecology", this paper analyzes the dialectical relationship between land use function and land use type, and classifies the national standard according to the present situation of land use. The spatial classification and evaluation system of Sansheng was established. The pattern and variation of Sansheng space in China from 1990 to 2010 are revealed. The results show that the production space is mainly distributed in the main urban agglomerations and grain producing areas southeast of Hu Huanyong line. The expansion areas are mainly distributed in the Northeast Plain, Northwest Xinjiang, Ningxia, Lanzhou Xining, Sichuan Basin, Bohai Rim, Yangtze River Delta, Xiazhang Spring, Pearl River Delta and so on. Hulunbeir prairie, Jianghan Plain, South Fujian hills and other areas; (2) the living space is mainly concentrated in the main cities and urban agglomerations of the whole country, showing "the east high and the west low, the north high and the south low;" The spatial pattern of large dispersion and small agglomeration is characterized by the large-scale, regional expansion of the three urban agglomerations around the Bohai Sea, the Yangtze River Delta and the Pearl River Delta, as well as the small scale of the major provincial capitals. The ecological space is mainly distributed on the northwest side of Hu Huanyong line, showing the spatial pattern of "west high and east low, south high and north low". 4) industrialization and urbanization are the basic driving force for the spatial change of Sansheng in China. Farmland reclamation in the northwest and northeast regions, urbanization in the North China Plain and the three urban agglomerations. The conversion of farmland to forest in the Loess Plateau is the main reason leading to the regional difference of Sansheng space. This paper can provide a reference for the classification planning and optimal decision of Sansheng space.
