青海可鲁克湖—托素湖自然保护区湿地生态系统服务价值评估

Evaluation of Wetland Ecosystem Service in Keluke Lake–Toson Lake Nature Reserve of Qinghai

在对青海可鲁克湖—托素湖自然保护区实地调查,通过卫星影像确定湿地类型、植被类型等基础上,结合已有研究成果,制定了湿地产品、调节大气、水文调节、净化去污、拦截泥沙沉积物、文化服务、支持服务等七类17个指标,对可鲁克湖—托素湖自然保护区湿地生态服务功能价值进行了计算与评估,结果为可鲁克湖—托素湖自然保护区湿地生态系统服务总价值为843 521.04万元·a-1,平均为12.50万元·a-1·hm-2,主要表现在调节大气、水文调节和维护生物多样性等方面,该保护区湿地管理应以保护为主,开发利用为辅,充分发挥湿地水文、大气调节和维护生物多样性功能。

The value of ecosystem service of Keluke Lake-Toson Lake Nature Reserve was evaluated based on a comprehensive investigation and division,determination through satellite image of wetland types and vegetation types.Seven factors applied for evaluation were wetland products,atmosphere regulation,water regulation,decontamination,purification of intercepting sediment deposit,recreation,education,cultural environment landscape,biodiversity and habitat index.Wetland ecosystem service value of the nature reserve was evaluated as 8 billion 435 million 210 thousand and 400 yuan a-1,value per hectare of wetland service was 125 thousand yuan a-1.The ecological service functions were mainly in regulating the atmospheric,hydrological regulation and maintenance of biological diversity.The management of the nature reserve is focused on the protection,with side measures for development.
