摘要:明晰生态系统服务的演变特征，有助于针对性的提出区域生态系统服务提升决策，对于维持和改善人类福祉、促进城市可持续发展具有重要意义。以深圳市为例，选取11种生态系统服务，以街道为基本空间单元，对生态系统服务结构特征进行分类，进而探究生态系统服务的长时序演变轨迹。结果表明，深圳市生态系统服务簇有6种类型，分别为水文调节主导型、文化支持潜力型、服务枯竭型、水文调节控制型、水源消耗型、生态保育型；1980-2015年深圳市大部分地区的生态系统服务簇结构稳定，变化明显的地区大多毗邻香港；生态系统服务簇的时空演变轨迹类型有8种，以持续型轨迹为主；生态系统服务簇的时空演变轨迹与城市扩张具有一定的一致性，表明城市扩张对生态系统结构和功能影响的主导性。



Abstract:It is of great significance to clarify the evolutionary features of ecosystem services (ES), which not only provides policy-making basis for the improvement of ecosystem services, but also helps maintain and enhance human well-being as well as leads to the sustainable urban development. In this study, we developed a new approach to cluster the spatiotemporal change trajectories of ecosystem services based on ecosystem service bundles. Taking Shenzhen City as an example, we determined the ES bundles at sub-district level based on the combination of 11 selected ecosystem services, and then explored the spatiotemporal evolution of ecosystem services in long time series. From 1980 to 2015, there were six ecosystem service bundles. The spatial distribution of the six kinds of ecological service bundles had little change, and the changing areas were mainly adjacent to Hong Kong. In addition, eight evolution trajectories were identified, most of which were stable in long-term. Furthermore, the spatiotemporal evolution of ecosystem services is consistent with urban expansion to some extent, which indicates that urban expansion may determine the structure and function of urban ecosystem.
