摘要
快速城镇化发展影响区域生态系统服务功能,本文以吉林中部城市群域为研究对象,评估单项及综合城镇化发展水平;测算生态系统服务总价值,并分析城镇化发展水平与生态系统服务价值之间的因应关系。结果显示:城镇化发展水平逐渐上升,相反生态系统服务总价值下降。通过对城镇化发展水平与生态系统服务总价值的关系进行曲线拟合发现,生态系统服务总价值随综合城镇化水平、人口城镇化水平、经济城镇化水平和生活方式城镇化水平的提高而降低,随景观城镇化水平提高呈现先降低后升高的态势。这表明,城镇化发展对生态系统可能造成的影响,即城镇化通过改变生态系统结构和循环过程,削弱区域的生态系统服务价值。
The process of urbanization promoted economic growth, facilitated population concentration and industrial upgrading, but there is inherent coupling relationship between urbanization and ecosystems, so ur- banization triggered a series of ecological problems, and also led ecosystem services value＇s systole. There- fore, in the early and mid stages of urbanization development, high speed and regional ecological environ- ment was deterioration, ecosystem services features were shrank, the process of urbanization has thus been restrained; With the development of urbanization in the later stable stage, ecological environment construc- tion investment expand appropriately, smart growth appeared in ecosystem services features. Urban agglom- eration is a new city-area type that appeared in the process of urbanization development, with a high urban- ization development potential, and it is a sensitive areas where＇s ecological environment problem is highly concentrated and intensified, to fit the interaction between urbanization development and ecosystem service value, can provide a theoretical basis to sustainable development of urban agglomeration areas. In this paper, in case of the Jilin central urban agglomeration, defined the study period as the year 2003-2013, assessed the level of individual and integrated urbanization in the Jilin central urban agglomeration, and used the applica- tion of the ecosystem service unit value table to calculation total value of ecosystem services in Jilin central urban agglomeration, and analyzed the element response relationship between the level of urbanization devel- opment and the ecosystem services value.
