Research Of Sustainable Development Of The Bohai Sea Region Based On Ecological Footprint

With the rapid development of urban and economic, the relation growing tension between the environmental pollution and supply and demand of resources in the Bohai sea Region. This relation precluded the sustainable development of economy and society, and has become a bottleneck which constraint the development of ecological and economic of the region. How to coordinate the relationship of the economic development and environmental protection is very important to the sustainable development of the region. Therefore, this thesis applies a theoretical model of ecological footprint to quantitative evaluation sustainable development of the Bohai Sea Region. By calculates 2000-2007 years'ecological footprints and ecosystem carrying capacity and carry on system's analysis to obtain quantitatively the state of sustainable development and clarify the direction of sustainable development, for the sustainable development of the region to provide strategic guidance.The main research results are as follows:(1) The per capita ecological footprint of the Bohai Sea region and the total ecological footprint both raised in 2000-2007. Ecological capacity per capita and total ecological capacity to maintain a relatively stable state of affairs, there is no wave. This leads to the widening of the total per capita and the ecological deficit ecological deficit year by year Bohai Sea region, the per capita ecological footprint serious cost overruns, increased from 2000 to 2007 1.393hm2 2.437hm2, an increase of 43%, higher than the national average, the ecological environment in overload, is not in the sustainable development situation.(2) The 2000-2007 million Yuan Bohai ecological footprint of GDP decline year by year, from 2000 1.8732hm2/million in 2007 down to 1.0679 hm2/million, down 43%, with that optimize the industrial structure adjustment and transformation in Bohai Rim, the efficiency of resource use is improved in the year(3) The Ecological footprint is arise except Tanjing in bohai rim in 2000-2007, diversity of other provinces and cities showed a downward trend in volatility, That shows a lower diversity of biological footprint in the Bohai Sea region. In addition to the development of capacity development in Beijing is relatively stable, Other provinces and cities showed a rising trend. By increasing the diversity of the types of land use, balanced use of different types of land resources, to improve the development capacity.(4) The ecological pressure index in Bohai Sea ecological pressure index is in a relatively stable state in 2000-2007, not in the Security level. The ecological footprint index and the ecological and economic coordination index showed an upward trend year by year, this implies the ability of the ecology is continuously improved in the Bohai Sea region, but still in poor ecological coordination level, also need to further strengthen ecological construction. The sustainability Index is slowly rising year by year, this showed that the ecological environment of Bohai Sea region has improved, but still at a low level, the task of economic development and the ecological construction are heavy.
