| 随着城镇化推进，生态空间屡遭蚕食，制约了城市生态系统服务功能的发挥。森林作为城市中生态–社会效益最为显著的生态系统之一，对公园城市生态服务水平提升至关重要。以公园城市首提地天府新区成都直管区为例，基于公园城市理念以及城市森林的生态–社会属性，初步构建森林生态系统服务评估体系；综合评估结果及森林生境调查，从公园城市森林生态建设的角度出发，提出构建山脉浅丘生境森林、城镇生境森林、道路交通旁生境森林、溪河流生境森林以及湿地生境森林5种典型生境森林类型；同时基于生态系统服务综合评价，明确11个核心森林及其生境构建目标；最后运用最小成本路径模型识别连接生态核心的生态廊道，完善“十一核心—多条绿带”的森林生态网络格局，为天府新区森林生态建设提供科学依据。 |

| Abstract: |
| As urbanization advances, the ecological space has often been eroded, which restricts the function of urban ecosystem services. As one of the ecological systems with the most significant ecological and social benefits in cities, forests play a critical role in improving the ecological services of park cities. Taking Tianfu New District of Chengdu City as a case, the research has preliminarily constructed the evaluation system of forest ecosystem services on the basis of the park city concept and the ecological and social attributes of urban forest. Through evaluating the ecosystem service and investigating the local forest habitats, it proposes the hill habitat forest, town habitat forest, roadside habitat forest, stream and river habitat forest and wetland habitat forest from the perspective of park city forest ecological construction. Moreover, it built up 11 core forest habitats and their construction objectives based on the comprehensive evaluation of ecosystem service. The minimum cost path model is applied to identify the ecological corridors connecting the ecological core and improve the forest ecological network pattern of “11 cores - multiple green belts”, which provides the theoretical basis for forest ecological construction of Tianfu New District. |
