【摘要】：永定河作为北京重要生态屏障的核心,其生态建设和管理具有重要意义。研究通过建立永定河生态服务价值增量评价指标体系,评价永定河生态修复工程建设后生态服务价值增量。研究结果表明:永定河生态服务价值增量为482.77亿元。在服务价值增量中,文化服务、支持服务、调节服务、供给服务分别占73.24%,23.28%,2.74%和0.74%。与永定河生态修复工程建设前生态服务价值存量对比分析发现,工程建设带来的生态效益增加明显,生态服务价值增加了1.12倍。生态修复工程对房地产价值增值及沿河地区产业发展推动作用明显,其中景观美学价值增加260.60亿元,产业贡献价值增加112.37亿元。此外工程建设对永定河调节气候功能和净化空气服务价值提升作用显著。研究科学评价了工程生态效益,也为动态监测和分析河流生态状况,开展定量生态管理提供经验与借鉴。
[Abstract]:As the core of Beijing's important ecological barrier, Yongding River's ecological construction and management is of great significance.Through establishing the evaluation index system of ecological service value increment of Yongding River, this paper evaluates the increment of ecological service value after the construction of Yongding River ecological restoration project.The results show that the increment of ecological service value of Yongding River is 48.277 billion yuan.In the increment of service value, cultural service, support service, adjustment service and supply service account for 23.282.74% and 0.74% respectively.Comparing with the stock of ecological service value before the construction of the Yongding River ecological restoration project, it is found that the ecological benefit of the engineering construction is obviously increased, and the ecological service value has increased by 1.12 times.Ecological restoration works can promote the value increment of real estate and the development of industry along the river. The value of landscape aesthetics is increased by 26.06 billion yuan and the value of industry contribution is increased by 11.237 billion yuan.In addition, the construction of the Yongding River to regulate the climate and improve the value of air services.It also provides experience and reference for dynamic monitoring and analysis of river ecological situation and quantitative ecological management.
