在评述国内外相关研究的基础上,利用遥感土地利用数据和统计资料,应用定量分析和GIS空间分析技术从定性与定量的角度系统全面地开展了珠江三角洲巨型城市区域土地利用变化的人文因素研究.定性分析结果表明:珠江三角洲土地利用变化与人口、经济发展、城市化与工业化及政策因素密切相关,这些因素深刻影响着该区域的土地利用变化.定量分析是对定性分析的验证,定量分析结果表明:影响珠江三角洲巨型城市区域土地利用变化的因子可归纳为人口、经济发展水平、城市化与工业化、农业产业结构调整、区域产业结构调整和外资等6个因子,并且各因子的影响作用大小不同.
After a brief review of the studies on the human dimensions of the land use changes within and outside China, this paper, taking the Pearl River Delta as the case study area, makes a thorough and careful study on the human dimensions that affect the land use changes in China's mega-urban region from the angles of qualitative and quantitative analysis by applying GIS spatial analysis techniques and the SPSS statistic analysis techniques (such as the factor analysis and the regression analysis) together upon the data collected from the government materials, the statistical data and the on-the-spot investigation records. The results of this research consist of two parts: first, the qualitative analysis shows that the human dimensions, including population, economic growth, urbanization and industrialization, government policies and so on, have a strong correlation with the land use changes in the Pearl River Delta, and all of these human dimensions have greatly affected and will continue to affect the land use changes in the mega-urban region of the Pearl River Delta. Second, the quantitative analysis, being the further and verified step of the qualitative analysis, reveals by means of the factor analysis and the regression analysis techniques that the major human dimensions that have influenced the land use changes are population factor, economic development level factor, urbanization and industrialization factor, agricultural structure adjustment factor, regional industrial structure factor and foreign investment factor. Clearly, this result, to some extent, is consistence with the conclusion of the qualitative analysis.
