Abstract:: In this paper, Guangdong Province was taken as an example, comprehensive evaluation index system 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 coordination 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, eastern 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 improvement of social, economic and ecological benefits in the future urban construction.
