Assessment of Forest Ecosystem Service Function in Hilly Areas of Beijing

文章对北京市浅山区森林生态系统的多种生态功能进行评估,从调节服务、支持服务以及文化服务3方面构建适宜的森林生态系统服务评价指标体系。综合运用Invest、USLE模型、ITREE效益计算器以及GIS空间分析技术,对浅山区森林生态系统涵养水源、固碳释氧、土壤保持、生境保护、森林游憩生态系统服务功能进行评估,识别关键保护区域,并提出相应的保护修复措施,为北京市林业可持续发展和生态保护修复优化战略提供一定的基础与科学依据。

The ecological functions of forest ecosystem in Hilly Areas of Beijing are evaluated,with the aim at providing the scientific basis for the sustainable forestry development and the optimization strategy of ecological protection and restoration in Beijing.An appropriate ecosystem service evaluation index system is established from the three dimensions of regulating,support and cultural services.The Invest,USLE model,ITREE benefit calculator and GIS spatial analysis technology are comprehensively applied to assess the forest ecosystem functions like water conservation,carbon fixation and oxygen release,soil conservation,habitat protection and forest recreation ecosystem in suburban hilly areas,and identify the key protected areas.Then the corresponding protection and restoration measures are proposed.
