Degree Evaluation of Coordinated Development of Ecological Economy in Poyang Lake Ecological Economic Zone

The regional ecological economy is a complex and comprehensive problem. In this paper, a Degree of Coordinated Development of Ecological Economy (DHDEE) is proposed to measure the relationship between eco-environment and economic development in the Poyang Lake Eco-economic Zone to meet the demands of the regional construction. The satellite images in 1990, 2000 and 2008 are selected to classify the land use types and the area of every administrative unit. GDP is selected to measure the levels of the economic development, and the ecosystem service value is used to measure the value function of the ecological environment, and thus the DHDEE of every unit can be calculated and the degrees of the coordinated development of the three major industries and the eco-environment can be analyzed separately, which could provide a scientific basis for the coordination between the socio-economic system and the eco-system in the Poyang Lake Eco-economic Zone.
