| 摘要: |
| 已有对城市生态系统服务功能优化的研究通常是“供给”导向下的增量研究，很少考虑到当地的人类价值取向变化下的实际需求对生态系统造成的负面效应，这些当地“需求”的负面效应直接影响城市生态系统服务提供的“供给”效益质量，使其在空间地域上的“供给-需求”错位、失衡，造成地方规划管理上的被动性和盲目性，这一现象在生态用地和建设用地交错的特大城市郊区的半城市化地区最为显著。以上海为例，探讨基于人本需求的特大城市半城市化地区生态系统服务主导功能优化思路；以乡镇街道为基本单元对半城市化地区进行解构，评价其供给、调节、支持、文化娱乐游憩等生态系统服务的功能现状，通过人本需求视角的聚类分析定位乡镇单元的生态主导功能，并据此提出生态系统服务的优化思路；旨在通过支持空间规划决策来有效控制半城市化的负面效应，使局部单元的生态服务价值优化与总体城市生态系统服务提升的目标达成一致。 |

| Abstract: |
| Extant researches on the optimization of urban ecosystem services are usually "supply-oriented", and rarely take into account the feedback that localized human needs may cause to the ecosystem. The negative effects of these local "demands" directly affect the quality of the "supply" benefits provided by the urban ecosystem services, causing them to displace and imbalance the "supply-demand" in the spatial units, resulting in passivity and blindness in local planning and management. This phenomenon is most pronounced in peri-urban areas of suburban megacities where ecological land confronts built-up land. This article takes Shanghai as an example to explore the strategies for the optimization of urban ecosystem services based on township units' ecological dominant function in megacities' peri-urban areas from the perspective of people-oriented needs. Deconstructing the peri-urban areas with township units, this research evaluates the function of the ecosystem services including supply, regulation, support, and cultural recreation of the Shanghai ecosystem, constructing the cluster analysis from the perspective of people-oriented needs to define the ecological dominant functions of the township units and optimization strategies accordingly. The purpose of this paper is to effectively control the negative effects of the development of peri-urban areas by supporting spatial planning, such that the optimization of the ecological service value of local units is consistent with the goal of improving overall urban ecosystem services. |
