Abstract:

A quantitative assessment of the Coordination Degree between Environment and Economy(CDEE)can effectively identify whether the relationship between environment and economy is in the state of coordination. Although researchers have done a lot of studies in this area， it is still a disputable question on how to make a reasonable quantitative assessment of CDEE. Based on the relationship between the changes of ecosystem service value and the regional economic development， a method was designed for the quantitative assessment of CDEE. The changes of ecosystem service value (ESV) in Daqing city were analyzed by using the land use data in 2001 and 2006. The parameters were revised by using the methods and models of ecological value estimation in view of the actual conditions of the study area， and the CDEE of Daqing was evaluated by using the method mentioned above. The results indicate that the total ecosystem service value of Daqing city descended from 18.247 billion yuan to 18.069 billion yuan during the period of 2001 and 2006， and the descending ratio was 0.98%; the regional eco-economic development was overall at a low disharmonic level， and the CDEEs of Northwest were higher than those of Southeast. The eco-economic development of Lindian County， Duerbete County， and Zhaoyuan County were at a low harmonic level， while Zhaozhou County and four districts except Sartu were at a low disharmonic level; however， Sartu district was at a severe conflict level. So more attention should be paid to strengthening the protection of eco-environment and promoting the harmonious development of eco-economy for a sustainable development of Daqing city.
