Based on the EF(ecological footprint ) model and it's relative researches, the author calculated china's ecological footprint and biological capacity between 1961-2001 to explore the ecosystem fluctuations brought by the population and economy increase. The results show that ecological deficits occurred in 1980's and then continued to increase, which demonstrate that great human-environment conflicts existed, and China was in a state of unsustainable development. The changes of unreasonable production and consumption model are necessary.
