摘要
文章以北京地区为例,运用生态资产综合指数、生态系统服务价值评估等方法来测算北京地区2009~2019年生态资产及其生态服务价值的变化,进而探讨对城市生态福祉的影响程度。结果表明:北京地区生态资产核算大体可分为城市森林、绿地和湿地的核算;生态资产综合指数整体下降14.73%,其中湿地和绿地降低明显;从生态系统类型来看,主要以城市森林为主,其次是绿地和湿地;从生态服务类型来看,以调节服务和支持服务为主,而供给和文化服务占比较少;生态系统服务价值逐年增加,预示着城市居民的生态福祉保持着改善趋势。针对研究结果,提出加强城市湿地的保护和管理,提高文化服务价值能力,建立城市生态系统管理部门等建议。
Taking Beijing as an example, this paper uses an ecological asset comprehensive index and ecosystem service valuation to measure the change of the ecological asset and the ecosystem service value in Beijing from 2009 to 2019, discusses the impact on urban ecological well-being. The results show that the accounting of ecological assets in Beijing can be roughly divided into the accounting of urban forest, green space and wetland. The overall index of ecological assets decreases by 14.73%, especially the wetland and green space decrease significantly. Regarding ecosystem types, the urban forest is the major ecosystem, followed by green space and wetland. For ecological services, regulation and support services are the main parts, while supply and cultural services are relatively small. The value of ecosystem services increases year by year, indicating that the ecological well-being of urban residents keeps improving. According to the research results, suggestions are proposed, such as strengthening the protection and management of the urban wetland, enhancing the ability of the cultural service value and establishing the urban ecosystem management department.
