Abstract

Based on the calculation of actual yield per unit area in 2002, this paper analyzed the ecological footprint and its composition of each province in China. The results showed that there was a significant difference in the ecological footprint and its composition among different provinces, e. g., cropland changed from 0. 078 hm2 x cap(-1) in Shaanxi to 0.126 hm2 x cap(-1) in Beijing, grazing land changed from 0.020 hm2 x cap(-1) in Jiangxi to 0.372 hm2 x cap(-1) in Xizang, forestland changed from 0.020 hm2 x cap(-1) in Guizhou to 0.209 hm2 x cap(-1) in Beijing, fishery area changed from 0.001 hm2 x cap(-1) in Xizang to 0.011 hm2 x cap(-1) in Shanghai, built-up area changed from 0.013 hm2 x cap(-1) in Guizhou to 0.045 hm2 x cap(-1) in Neimenggu, and fossil energy changed from 0.251 hm2 x cap(-1) in Guangxi to 2.854 hm2 x cap(-1) in Shanxi. The eastern and southern provinces were mostly in a state of ecological deficit, while the western and northern provinces were mostly in a state of ecological remainder. As for the relationships among ecological footprint, economic development and technological progress, great difference existed in different provinces, e. g. , the ecological footprint was about 1 hm2 x cap(-1) in Fujian, Henan, Sichuan, Anhui, Yunnan, Shaanxi and Guizhou, while the GDP per capita changed from 1.35 x 10(4) yuan in Fujian to 0.3 x 10(4) yuan in Guizhou, and the ecological footprint per 1 x 10(4) yuan GDP changed from 0.74 hm2 in Fujian to 3.51 hm2 in Guizhou. Therefore, to resolve the conflicts between the shortage of natural resources and the economic development of China, emphasis should be put on the provinces with big ecological footprint per capita, low GDP per capita, and high ecological footprint per 1 x 10(4) yuan GDP. In these provinces, economic growth mode and industrial structure should be changed, dependence of economy on natural resources should be decreased, use efficiency and economic output of natural resources should be improved, and ecological, resources and economic sustainability should be realized.
