Abstract


With the deepening of the concept of sustainable development, the focus is gradually transformed from a qualitative connotation of quantitative evaluation metric study. Bearing capacity is one of the core tools of quantitative evaluation of sustainable development, in which the ecological carrying capacity is a portrait of the bearer of the natural resources and environment on the size of the regional economic and social development efforts. Quantify the relationship between the ecological carrying capacity and economic development, to seek coordinated development between the ecological environment and economic and social system is an inevitable requirement for regional sustainable development. With the social and economic development, has a \Construction of Poyang Lake Ecological Economic Zone has become a global strategy in Jiangxi Province and upgraded to a national strategy, the coordinated development of the Poyang Lake ecological and economic research from the Carrying Capacity of great theoretical and practical significance. The ecological footprint is the measurement of the ecological carrying capacity of a traditional, more mature way, taking into account the importance of water resources to the Poyang Lake ecosystem carrying capacity virtuous circle, this paper introduces the model of the water footprint, water footprint analysis and ecological footprint analysis two The angles comprehensive characterization of Poyang Lake ecological carrying capacity. Poyang Lake ecological footprint and water footprint in nearly two decades (1989-2008) time series values ??calculated by the measurement model and to evaluate the individual load condition. Then, the ecological footprint, water footprint and the Poyang Lake area to the total economic output in constant prices and three industrial output value of the co-integration analysis determined the long-term equilibrium relationship between the four main conclusions are as follows: 1) nearly two decade, Poyang Lake ecological footprint and water footprint time series values ??has emerged as a volatile upward trend. So far, none of the ecological footprint and water footprint overload tended to decrease, but the surplus space. 2) Poyang Lake ecological footprint, water footprint and the total economy and three industries are cointegrated. Changes in the ecological footprint brought about by changes in GDP larger than the fluctuation of the water footprint of Poyang Lake GDP ecological footprint greater than the impact of the water footprint Lakes economic growth on the demand pressure is greater than the biologically productive land area demand for water pressure, Poyang Lake ecological footprint on the bearing capacity of the total economic output is less than the carrying capacity of the water footprint of the total economy. 3) in the three industries in the Poyang Lake area, the first industry efforts ecological footprint and water footprint are the largest, and Jiangxi Province as a major agricultural province is actually consistent. The tertiary industry's ecological footprint and water footprint Secondly, last second industry. Development of primary industry of biologically productive land and water resources, greater demand pressures, Poyang Lake ecosystem is less than the ecological carrying capacity of the primary industry and secondary industries. In addition, the three industries of the Poyang Lake ecological footprint and water footprint are in the same direction. Finally, to reduce the ecological footprint and water footprint demand pressures and increase the angle of ecological footprint and water footprint supply countermeasures to improve the regional ecological carrying capacity; industrial system of green national economic accounting system, the performance evaluation system, as well as the publicity and guidance and other aspects of the coordination of the ecological environment and the economic and industrial development policies and measures.
