若尔盖高原湿地区主要生态系统服务价值评价

Service Value Evaluation of Main Ecosystems of Ruoergai Plateau Marshes

利用2006年的卫星遥感资料,结合社会经济调查,运用生态系统服务价值评价方法,构建若尔盖高原湿地区主要生态系统服务价值评价模型,评价若尔盖高原湿地区生态系统服务价值。结果表明,2006年若尔盖高原湿地区生态系统服务价值为169.88亿元,其中物质生产价值和游憩价值19.61亿元,调节价值为150.27亿元。若尔盖高原湿地区生态系统具有巨大的服务价值,由经济上直接体现的物质产品生产价值和部分文化价值仅占小部分,往往在经济活动中被人们忽略的调节价值占生态系统服务价值较大比重。

With satellite remote sensing data, social, ecological and economic data, Ruoergai plateau marshes ecosystem services were evaluated by building an evaluation model and using a series of ecosystem service evalu- ation methods. In result, the total service of Ruoergai Plateau Marshes is 16.99 billion Yuan （RMB） in 2006. Among this, 1.96 billion Yuan is physical production and recreation value and 15.03 billion Yuan is regulation value. In conclusion, Ruoergai Plateau Marshes has huge ecosystem service. Physical production and recreation- al value are only small part of total ecosystem service. Regulating value has significance to total service. Protect and wise use of wetland resource is the way to keep Ruoergai Plateau Marshes ecosystem service in high level.
