Research On Calculation Of Liaoning Province's Ecological Footprint And Its Factors

Essential requirements of sustainable development is to achieve a "Human-Society Economy" harmonious and healthy development of the ecosystem. To achieve sustainable development, on the one hand we have to taken into account renewable and alternative regional resources capacity, cycle life support system and purification capacity and biodiversity conservation, on the one hand we have to pay full attention to the enjoyment of equal rights of use of ecosystem resources.Quantitative measurement of regional development should be sustainable and inter-regional comparison, a clear commitment to the global ecological responsibility, and promote the realization of eco-ethics fair. In recent years, rapid development of the ecological footprint model results visually and with a regional comparability, good to meet the above requirements, obtain the relevant international agencies, government departments and research institutions recognized as an international sustainable development is an important measure in Methods.Firstly, the ecological footprint model theory was sorted and summarized, respectively, from concept and calculation of two aspects, then the ecological footprint model was evaluated. Then it introduced the natural conditions and in Liaoning Province, economic development and ecological footprint model based on the Liaoning Province in 11 years 1997-2007 to calculate the ecological footprint. Ecological footprint and ecological carrying capacity analysis to arrive at the past 11 years in Liaoning Province has been in a growing ecological deficit conclusions Next, in order to discuss the impact of factors of ecological footprint, ecological footprint model of economic indicators is established, and principal component analysis was brief, principal component analysis, combined with the economic indicators of ecological footprint model, the factors affecting ecological footprint analysis. Finally, the conclusions drawn on the analysis, some suggestions have been given to how reduce the ecological footprint and ecological deficit.
