摘要: 城乡二元结构下生态环境的协调发展对区域发展具有重要影响。笔者基于3S技术,借助Landsat影像解译结果,采用市场价值法、动态分析法、敏感性分析法,研究重庆市巴南区不同城镇化率地区2005—2015年生态服务价值变化。研究结果表明:生态系统服务价值定量评估方面,研究期内核心区生态服务价值小幅增长,由24.53亿元升至25.03亿元,涨幅是2.04%,边缘区生态服务价值大幅减少,由63.20亿元降至57.99亿元,降幅是8.98%,2个区域生态服务单项功能变化不同,但水源涵养服务价值均呈下降态势;生态服务价值动态变化方面,研究期内边缘区的生态系统服务功能效益先上升后下降,核心区则先下降后上升。

Abstract: The coordinated development of the ecological environment under the urban-rural dual structure has an important impact on regional development. Based on the 3S technology, and with the aid of Landsat image interpretation results, the market value method, dynamic analysis and sensitivity analysis were adopted to study the change of ecosystem service value of the areas with different urbanization rate in Banan district from 2005 to 2015. The research results show that: In terms of quantitative evaluation of ecosystem service value, during the research period, the value of ecosystem service in the core area has increased slightly, from 2.453 billion CNY to 2.503 billion CNY, which has increased by 2.04%; while the value of ecosystem services in the fringe area has decreased significantly, from 6.32 billion CNY to 5.799 billion CNY, which has decreased by 8.98%. The single function of ecological services in the two regions has different changes, but the service value of water conservation function of both intends to decrease. In terms of the dynamic change of ecosystem service value, during the research period, the ecosystem service function benefit in fringe area firstly increases and then decreases, while that in the core area firstly decreases and then increases.

Key words: enviroment engineering, resources and environment, land use change, ecosystem service value, dual structure, Banan district
