摘　　要：“城市森林公园”作为城市化进程下出现的一类特殊“森林公园”,是改善城市生态环境、推进城市可持续发展的关键要素之一,能够显著提升居民对城市绿地的需求以及改善居住环境.成都市龙泉山城市森林公园是国内外少有的、布局在城市中心的山地型城市森林公园,不仅能提供生态产品、维系生态安全,也能满足人民日益增长的对食物、环境质量以及精神文化的需要.为全面评估龙泉山城市森林公园的生态价值,采用文献类比法和问卷调查法,建立针对该地区的生态系统服务评估体系;进一步结合层次分析法对该指标体系进行检验,最终确定具体的评估体系.在评估体系中共有3项一级指标[生态物质产品(权重为0.412 6)、生态调节(0.327 5)、人居文化(0.259 9)],8项二级指标[产品生产(0.206 3)、资源供给(0.206 3)、生物多样性(0.194 4)等],以及23项三级指标[空气负氧离子(0.154 7)、栖息地质量(0.095 9)、生态健康效益(0.075 5)等].从评估体系的一、二级指标权重可知生态物质产品供给是龙泉山城市森林公园生态系统中的主要服务功能.然而,从三级指标权重发现民众对“城市森林公园”生态系统服务价值的认知与观念逐渐从产品与资源的供给服务转向为文化服务.本研究针对龙泉山城市森林公园构建的生态系统服务价值评估体系具备一定可行性和可推广性,可为国内外其他“城市森林公园”生态价值科学评估及实现机制提供参考.(图3表7参38)As a special ecosystem, an urban forest park, which is different from a regular “forest park”, is one of the key elements involved in improving the urban ecological environment and promoting the sustainable development of a city. The “urban forest park” can also significantly improve living conditions by acting as a greenbelt. The Chengdu Longquan Mountain Urban Forest Park is a rare mountain urban forest park located in the center of the city. This “urban forest park” not only provides more ecological products and maintains ecological security but also meets the growing needs of people for food, environmental quality, and spirituality.To comprehensively assess the ecological value of the Chengdu Longquan Mountain Urban Forest Park,this study used the literature analogy and questionnaire survey methods to establish a targeted ecosystem service assessment system in this study area. In addition, combined with the hierarchical analysis method,the indicator system was tested, and the specific evaluation index was determined. In the Longquan Mountain Urban Forest Park Ecosystem Service Value Index System, three first-level indicators, such as ecological material products(with a weight of 0.412 6), ecological regulation(0.327 5), and dwelling culture(0.259 9);eight secondary indicators, such as product production(0.206 3), resource supply(0.206 3), and biodiversity(0.1944);and twenty-three tertiary indicators, such as air negative oxygen ion(0.154 7), habitat quality(0.095 9), and ecological health benefit(0.075 5), were identified. From the weights of the first and second indicators, it was clear that the supply of ecological material products is the main service function in the Longquan Mountain Urban Forest Park ecosystem. Moreover, from the weights of the third indicator, the public’s cognition and concept of the ecosystem service value of the “urban forest park” gradually shifted from the supply service of products and resources to cultural services. In summary, the ecosystem service value assess
