【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。
[Abstract]:Rapid urbanization affects the function of regional ecosystem services. This paper takes the central Jilin urban agglomeration as the research object to evaluate the development level of individual and comprehensive urbanization, and to calculate the total value of ecosystem services. The relationship between urbanization development level and ecosystem service value is analyzed. The results show that the urbanization development level increases gradually. On the contrary, the total value of ecosystem services decreased. Through the curve fitting of the relationship between the development level of urbanization and the total value of ecosystem services, it was found that the total value of ecosystem services with the level of comprehensive urbanization, the level of population urbanization, The level of economic urbanization and the level of lifestyle urbanization decrease with the increase of the level of landscape urbanization, which shows that the development of urbanization may have an impact on the ecosystem. That is, urbanization weakens the value of ecosystem service by changing ecosystem structure and cycle process.
