摘要
结合北京市平原造林相关数据,运用生态经济学原理和方法,采用影子工程法、机会成本法和替代成本法等方法,对北京市100万亩的平原造林生态系统服务价值进行评估。结果表明,北京市平原造林生态系统服务的价值为325.89亿元,各生态服务功能的重要性由大到小依次为调节气候功能、净化空气功能、固碳释氧功能、降低噪声功能、固土保肥功能、涵养水源功能。研究结果为进一步推动北京市平原造林工程建设、制定生态补偿政策及确定生态补偿标准提供了参考。
Based on research progress on economic value of ecosystem services, taking the plain afforestation data in Beijing as the study area, this paper explores the ecosystem service value evaluation of the 6.67×104 hm2 plain afforestation area. Shadow engineering method, opportunity cost method and opportunity cost method are used. The results show that, the total plain afforestation ecosystem service value is about 325.89×108Yuan. The importance of each ecological service function, in descending order： climate regulation function, air purification function, function of fixing carbon and releasing oxygen, solid soil fertilizer function, reduce the noise function, the function of water conservation. The results provide reference for further promoting the Beijing plain afforestation project construction and the ecological compensation policy and determine the ecological compensation standard.
