摘要:

生态系统服务功能能够促进人与自然和谐共生,探究宁夏贺兰山国家级保护区生态系统服务功能对统筹山水林田湖草沙一体化保护和系统治理具有重要意义。以森林和草地生态系统长期观测研究与服务功能评估系列国家标准为基础,应用林业小班数据,结合分布式测算方法,选取保育土壤、林木养分固持、涵养水源、固碳释氧、净化大气环境等5项生态系统服务功能对保护区森林和草地生态系统进行效益评估。结果表明:宁夏贺兰山国家级自然保护区森林和草地生态系统服务功能物质量在空间分布格局中呈东北高、西南低的变化趋势;价值总量为28.27亿元/a,其中,涵养水源、保育土壤功能位列前2位,是宁夏贺兰山国家级自然保护区森林和草地生态系统的主要服务功能。保护区未来应进一步加强森林经营管理,合理优化树种结构和林龄结构,提升森林生态系统质量,充分发挥生态系统服务功能。

Abstract:

Ecosystem service functions can promote harmony between human and nature.Exploring the ecosystem service functions of Helan Mountain National Nature Reserve is of great significance for adopting a holistic approach to conserving and management our mountains,rivers,forests,farmlands,lakes,grasslands,and deserts.Based on a series of national standards for long-term observation research and service function evaluation of forest and grassland ecosystems,as well as applying a distributed calculation method based on forestry compartment data,we selected five forest and grassland ecosystem service functions,namely,soil conservation,forest nutrient sequestration,water conservation,carbon sequestration and oxygen release,atmospheric purification to assessed their benefits in terms of physical quality and value quantity.The results show that the physical quality of forest and grassland ecosystem services in the Helan Mountain National Nature Reserve in Ningxia present present a spatial distribution pattern of high in the northeast and low in the southwest;the total value is 2.827 billion yuan/a,of which the functions of water conservation and soil conservation in the top two.There are the main services function of forest and grassland ecosystems in Ningxia Helan Mountain national Nature Reserve.The Helan Mountain National Nature Reserve should further strengthen forest management,optimize tree species and age structures,enhance the quality of forest ecosystems,and fully leverage the ecosystem services.

Key words: ecosystem services, water conservation, value assessment, services function
