The authors apply ecological footprint method to evaluate the sustainable development and ecological security of Zhejiang Province by the time series.The paper constructs the new evaluation index system of ecological security and introduces the model of ecological tension index

ecological occupancy index

and ecological economic coordination index.Taking Zhejiang Province as a case study area

the paper introduces the concepts of change rates and the scissors difference to quantitatively analyze the trends of ecological footprint and index system of ecological security in the province from 2000 to 2006.Results show that the per capita ecological footprint of Zhejiang Province increased reversely with ecological carrying capacity and the per capita ecological deficit increased steadily.Ecological tension index increased from 2.34 in 2000 to 3.22 in 2006.In the same period

ecological occupancy index increased from 0.67 to 0.90 and ecological economic coordination index declined from 0.286 to 0.277.The sustainable development model of Zhejiang Province is not optimistic

its ecological environment is at risk

and its social economic development does not go well with ecological environment.
