The Urban Ecological Footprint Research Based on the Energy Analysis

On the basis of ecological footprint, the energy analysis theory is used to establish the urban ecological footprint model , the model is used to calculate the ecological footprint of Yantai and measure the regional sustainable development status.The influense that the international trade to the regional ecological footprint is considered in the article.The improved model is applied to analyse the enviroment status of eco-economic system of Yantai in 2008.The results indicate the ecological footprint of Yantai is 12.9082hm2, and the aquatic prdouct is 7.57 hm2 occupying 58.6% of the total footprint, the ecological footprint is 0.477 hm2, the ecological footprint is bigger than the ecological capacity.
