【摘要】：GIS空间分析技术为空间形态的精准判别提供了新的路径和研究视角。本文通过高分辨率Google Earth影像提取2013年珠江三角洲城市群的工业生产空间分布信息,运用分形模型、形态紧凑度、空间离散度、密度指数定量分析珠三角工业生产空间的形态特征,采用GIS空间分析并结合社会经济统计分析进一步探讨了影响其分布的主要因素。结果表明:12013年珠江三角洲城市群的工业生产空间共有2604.71 km~2,其空间分布呈现典型的"核心—边缘"结构,并且形成了交错式、零散式和集中式3种分布模式。2珠江三角洲城市群的工业生产空间具有很强的分形特征,核心区的分形维数整体小于外围地区,而空间结构的稳定性高于外围地区;珠三角各市中,工业生产空间形态紧凑度最高的为珠海、最低的为广州,而空间离散度最高的为惠州、最低的为中山;珠三角各市工业生产空间的规模差异显著,与经济规模、人口规模、工业企业数等呈较强的正相关关系,而东莞、深圳、中山、佛山的密度指数过高,需加强工业生产空间的集约高效利用。3自然因素与交通条件、城镇化与开发区的发展、政策的引导和调控以及经济全球化是珠江三角洲城市群工业生产空间分布的主要影响因素。
[Abstract]:GIS spatial analysis technology provides a new path and research perspective for the accurate identification of spatial morphology. In this paper, the spatial distribution information of industrial production of Pearl River Delta urban agglomeration in 2013 is extracted by high-resolution Google Earth image. The fractal model is used to obtain the spatial distribution of the urban agglomeration in the Pearl River Delta. The density index is used to quantitatively analyze the morphological characteristics of industrial production space in the Pearl River Delta. The main factors influencing its distribution are further discussed by using GIS spatial analysis and social and economic statistical analysis. The results show that: (1) the industrial production space of the Pearl River Delta urban agglomeration in 2013 is 2604.71 km2, and its spatial distribution presents a typical "core-edge" structure, and forms a staggered pattern. The industrial production space of Pearl River Delta urban agglomeration has very strong fractal characteristics, the fractal dimension of the core area is smaller than that of the peripheral area, and the stability of the spatial structure is higher than that of the peripheral area. Among the cities in the Pearl River Delta, the most compact industrial production is Zhuhai, the lowest is Guangzhou, while the highest spatial dispersion is Huizhou and the lowest is Zhongshan. The population size and the number of industrial enterprises are positively correlated. However, the density index of Dongguan, Shenzhen, Zhongshan and Foshan is too high, so it is necessary to strengthen the intensive and efficient use of natural factors and traffic conditions in industrial production space. Urbanization and the development of development zones, the guidance and regulation of policies and economic globalization are the main factors affecting the spatial distribution of industrial production in the Pearl River Delta urban agglomeration.
