Abstract: The lower possession per capita of cultivated land resource is one of the important problems in Guangdong Province for all time and the trends of decrease will continue with further development of economy. In this paper, the spatial and temporal characteristics of the change of cultivated land resources were analysed using the statistics from 1949 to 1990, and 4 types were separated according to the grading of the cultivated land area and the cultivated land area per capital by yearly average variation. Type Ⅰ is the regions of most serious decrease in cultivated area including Shenzhen, Zhuhai, Guangzhou, Dongguan and Zhongshan. Type Ⅱ is those of more serious decrease in cultivated area, including Foshan, Jiangmen, Huizhou, Shantou, Chaozhou, Jieyang and Shanwei. Type Ⅲ is those of slight decrease in cultivated area, including Yunfu, Zhaoqing, Maoming, Shaoguan, Yangjiang, Qingyuan, Heyuan and Meizhou. Type Ⅳ is those of no decrease in cultivated area, including Zhanjiang. The characteristics of the spatial distribution of those regions are linked to economic development and population growth. Regions of type Ⅰ and Ⅱ are located at the core area, around the beaches of the Pearl River Mouth, while regions of types Ⅲ and Ⅳ located at the Eastern, Western and Northern of the province where economy is developing and population growth is slow.
