Abstract: On the basis of the theory of ecological footprint, China's ecological footprint in main years from 1978 to 2004 is analyzed.Depending on the long-term data,the curve of the general demand and supply of ecological footprint is depicted,and the trend of the long-term ecological footprint is observed to judge whether it was in equilibrium.The result is that ecological deficit has been increasing in the long-term.And in the end the ecological consistency of China is analyzed using econometric model.
