环境与经济协调发展是实现可持续发展的重要途径,也是可持续发展的基本要求。生态系统提供的服务功能是实现可持续发展的基础,其价值变化与社会经济发展密切相关,是区域生态环境变化结果的综合化与定量化,可作为表征区域可持续发展水平的一个综合指标。本文以2001-2006年大庆市土地利用变更调查数据为基础,参照谢高地等制定的中国陆地生态系统单位面积服务价值系数及评估方法,结合研究区实际情况对估算方法进行了修正,对土地利用变化所引起的大庆市生态系统服务价值变化进行了估算,并通过构建环境经济协调度指数(CDEE)对研究区环境与经济协调发展水平及区域差异进行了评估。结果表明:(1)大庆市生态系统服务价值由2001年的182.47亿元下降到2006年的180.69亿元,损失率为0.98%;(2)研究区整体的环境经济发展属于低度冲突水平,处于不协调状态;(3)研究区西北部的环境经济协调度高于东南部,其中林甸、杜蒙和肇源三县处于低度协调水平,除萨尔图区外的其他市辖区以及肇州县处于低度冲突水平,萨尔图区则处于严重冲突水平。
A quantitative assessment of the Coordination Degree between Environment and Economy(CDEE)ean 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 2006, and the descending ratio was 0.98%; the .069 billion yuan during the period of 2001 and 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.
