摘要: 投资自然资本(NC)、提升生态系统服务价值(ESV)是协同推进经济增长和环境保护的重要举措,其关键之一在于测算生态系统服务价值。基于2009~2016年重庆市各类土地利用类型面积的调查数据,测算了全市ESV,并结合研究期间各区县经济水平,系统分析了ESV与经济增长时空动态关系的演变。研究结果表明:(1)全市ESV在2009、2012和2016年分别是 4 011.29、4 000.63 和4 037.24 亿元,呈先降后升的U型变动。(2)变动的主要原因在于林地面积的变化,建设用地对林地等的占用导致了前期的下降,而退耕还林、天然林资源保护、三峡后续植被恢复等生态工程的实施促进了后期的上升。(3)从空间自相关关系来看,全市人均GDP与地均ESV负相关关系减弱,表现为“低高组合为主,双低双高为辅”,低-高聚类分布在渝东北和渝东南地区,高-高聚类分布在渝西地区。最后,因地制宜地提出实现经济和生态双增长的对策与建议。

Abstract: Investing in natural capital (NC) and improving the ecosystem services value (ESV) are important measures to promote economic growth and environmental protection cooperatively. One of the keys is to measure ecosystem services value. Based on the survey data of various land-use types in Chongqing from 2009 to 2016, The spatiotemporal distribution pattern of ESV in Chongqing is measured and calculated, then the spatio-temporal dynamic relationships between ESV and economic growth are identified during the study period. The results indicate that: (1) the ESV of Chongqing was respectively RMB 401.129, 400.063 and 403.724 billion in 2009, 2012, and 2016, respectively, documenting a U-shaped curve of decrease first and then increase, and ESV in the northeastern and southeastern parts of Chongqing was obviously higher than that of main city zones and western Chongqing. (2) The main reason for the trend is the change of forest land area. The occupancy of construction land led to the decline in the early stage, while the implementation of ecological projects such as conversion of farmland to forests, protection of natural forest resources and subsequent vegetation restoration of the Three Gorges Project promoted the increase of ESV in the later stage. (3) The negative correlations between GDP per capita and AESV of Chongqing were weakened according to spatial autocorrelation, which is manifested as “integrated high and low values took the main part, with dual high values and dual low values as auxiliary parts”, of which low-high clustering regions were distributed in northeastern and southeastern parts and high-high clustering regions were distributed in western parts and main city zone of Chongqing. Finally, decision-making references and suggestions would be put forward in this thesis to realize the dual growths on both economy and ecology in various districts and counties according to their local conditions in Chongqing.
