摘要
以广东省为例,利用遥感影像解译的土地覆盖数据和社会经济指标数据,基于多因素综合评价法,从社会、经济和生态3个方面构建了广东省土地集约利用综合评价指标体系,采用层次分析法(AHP)和特尔菲法确定指标权重,综合评价得出广东省21个地级市土地集约利用水平,通过聚类分析进行集约利用潜力级别划分。基于系统协调度模型分析,发现城市土地集约利用水平越高,社会、经济和生态3大子系统协调性越差。结果表明,广东省土地集约利用水平在空间分布上呈现明显的区域分异特征,表现为珠江三角洲>粤东>粤西>粤北,区位条件和经济发展状况对集约利用水平有重大影响。广东省在今后的城市建设中,要注重区域协调发展和社会、经济、生态整体效益的提高。
In this paper, Guangdong Province was taken as an example, comprehensive evaluation index sys- tem of intensive land use, in the aspects of society, economy and ecology, was established based on multi- factor comprehensive evaluation method, using land cover data interpreted by remote sensing image together with socio-economic data. The method of Analytic Hierarchy Process （AHP） combined with Delphi method was employed to ascertain weights of indexes. Land use intensity of 21 cities in Guangdong Province was computed through comprehensive evaluation and intensity potentiality level was divided by cluster analysis. Based on system coordination model, the regular pattern of the relationship between intensity and system co- ordination degree is found. Results show that land use intensity of different cities in Guangdong Province has an apparent regional difference feature in terms of spatial distribution, Pearl River Delta is the highest, east- ern Guangdong is the second, western Guangdong is the third and northern Guangdong Mountain District is the lowest. Location condition and economic development level have the fundamental influence on land use intensity. Guangdong Province should focus more on balanced regional development and integrated improve- ment of social, economic and ecological benefits in the future urban construction.
