Time Series Analysis of Ecological Footprint in Tieling City

Analyzes theoretically the ecological footprint and ecological capacity of Tieling City from 1995 to 2004.The result shows that in this time period the average ecological footprint,capacity and deficit were 2.07,1.22 and 0.851 hm2/cap,respectively,i.e.,the city is in a state of unsustainable development.In the total ecological footprint the largest proportion resulting from energy consumption is about 60%,up to 63% in 2003 down to 59% in 1999.The second largest one is cropland,about 26%～31% and,sequentially,the land for building,grazing land,aquatic area and forest land.Taking account of the footprint intensity and ecological efficiency of the city,an ecological strategy is proposed for its sustainable development with some advice given.
