Construction of an ecosystem service value evaluation system for the Longquan Mountain Urban Forest Park in Chengdu City Based on the Analytic Hierarchy Process北大核心CSCD

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 (0.194 4); 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 assessment system designed for the Longquan Mountain Urban Forest Park in this study has certain feasibility and extensibility that lays a theoretical foundation for the scientific assessment of ecological value and ecological value realization mechanism for other “forest parks” worldwide. © 2022 Authors.

基于VOSviewer的公园城市计量特征、热点与趋势北大核心CSCD

基于VOSviewer软件和文献计量学方法,以中国知网(CNKI)数据库和WoS核心合集SCI-Expanded数据库为数据源,获取知识图谱并进行可视化分析,探究近40年来公园城市的研究热点与未来发展趋势.结果表明:在文章发布特征方面,1980-2021年国内外学者对于公园城市领域的研究处于日益增长的活跃趋势,美国加州大学系统和中国科学院是该领域具有较高影响力的研究机构,并且各个机构之间的合作关系较为密切;在研究热点方面,建筑科学与工程学科在我国公园城市研究中占主导地位,环境生态科学是国际上的热点.城市公园的住宅价格、景观规划与设计是国内领域的热点主题,而生态环境与社会效益为国际领域的热点区.随着公园城市理念的逐步发展,该领域研究预计将继续维持增长的趋势,未来的研究可关注于生态系统服务尤其是与居民福祉的关联等方面.(图6表3参67)
