The Research Of Ecological City Base On The Ecological Footprint Model Of Jinan City

Currently, the high economic growth in China depends on the high consumption of the material resources and energy to a great extent, which is a kind of extensive economic growth mode and inevitably encounters the restriction of population, resources, energy and the pressure of the environment, faces the " bottleneck" of the limited resources.The authorities should pay much attention on how to change the traditional extensive economic development mode according to the scientific development conception to develop the low expenditure mode in accord with sustainable development, and to let our society and economy step into a benign circulation to make the economic growth can obey the rule of environment, also to accomplish sustainable development based on resources and environmental capacity.Ecological footprint and ecological deficit in Jinan city in recent decade are calculated in this paper by means of the basic theories of ecological footprint model and its calculation method.The purpose of this paper is to evaluate and measure the situation and extent of the sustainable development in the city ecological construction in Jinan city to provide the basis in establishing the policy of ecological city and in promoting sustainable development.The analyses and calculation of ecological footprint from 1995 to 2004 in Jinan city indicate that ecological footprint per capita increased from 1.6hm2 in 1995 to 2.1hm2 in 2004,30.6% increased during the decade. Nevertheless, there is not much change in ecological capacity per capita, with only 6.21% increased during the same period.The ecological deficit tends to increase gradually annually, while the ecological footprint for ten thousand Yuan GDP presents degenerative trend annually.Through analyzing the change of the ecological deficit of Jinan city and discussing the feasible approach to the construction of ecological city, the related suggestions are put forward, such as the population control, improvement of biology yield per unit of land, and adoption of new production technique, such as recycling, energy-saving technologies to improve the exploitation of the resources.
