Index System And Research Of Eco-efficiency Of The Poyang Lake Eco-economic Zone

The ecological environment is the foundation of human survival and development of social economy conditions. But for a long time on the ecological environment of human unreasonable development and utilization of accumulated a great deal of ecological environment problems, not only destroyed the ecological environment and restricted the economic and the sustainable development of human, the contradiction of eco- economic relations become increasingly acute.Ecological efficiency reflects the economic and social development of value and the ratio of the resource, energy consumption, it says economic growth and environmental pressures [1], the separation of relations. Reflected a enterprise, industry or region and the country's green competition ability, promote human to coordinate the relationship between environment and economy.Ecological footprint is a quantitative measure of human natural resources utilization new method, which is based on ecological land area sustainable development ability, judgment pressure and impact of human activities on the ecological environment. In this paper, based on this method, in the poyang lake ecological economic zone in 2011 as the research object, the concrete process of the construction of the index system of this method are introduced, the traditional method to calculate the ecological footprint in 2011 the per capita ecological footprint is 3.08862 hm2 / cap, per capita ecological carrying capacity of only 1.37530 hm2 / cap, ecological deficit is 1.71332 hm2 / cap, and according to the size of the deficit analysis of present situation of the sustainable development of poyang lake ecological economic zone in 2011. On the basis of the static model, the introduction of time sequence was calculated the ecological footprint of 21 years from 1991 to 2011, 21 years of an upward trend in the overall ecological footprint, ecological carrying capacity in reverse. From a long-term dynamic considerations, to join the economic data, to supplement and correction of model parameter, from the perspective of economics for data processing and analysis, it is concluded that the relationship between the economic, ecological variables.According to the results of the poyang lake ecological economic zone analysis of specific resources change and economic growth influence each other, cause analysis, and evaluation, puts forward the opinion of the targeted, provide the basis for the sustainable development of poyang lake ecological economic zone, improve the ecological efficiency, promote the benign development of ecological economy...
