御临河流域河流湿地生态系统服务价值评价

Ecosystem Services Evaluation of River Wetland in Yulinghe Watershed

御临河流域河流湿地具有非常重要的生态服务功能,包括直接使用价值和间接使用价值。直接使用价值有物质生产功能、水资源服务、旅游休闲功能、科研文化功能等,间接使用价值包括气体调节功能、水分调蓄功能及河岸带湿地污染净化功能的价值等。本研究采用市场价值法、碳税法、影子工程法、类比法及旅行费用法对御临河流域河流湿地生态系统服务价值进行了初步估算,其生态系统服务总价值为4.39亿元人民币,是2000年该流域GDP的28.52%。研究结果表明,御临河流域河流湿地生态系统的服务价值是不容忽视的。在进行流域规划管理时必须重视自然生态系统的潜在价值,才能保证流域生态系统的健康及可持续发展。
