流溪河国家森林公园森林生态系统服务功能间接价值评估

Assessment of the indirect forest ecosystem services in Liuxi river national forest park

从森林生态系统的效益出发,选取涵养水源、调节气候、净化环境、土壤保持、固碳释氧、维持生物多样性和医疗保健等因子,采用市场价值法、影子价格法、机会成本法等多种手段对流溪河国家森林公园的森林生态系统服务功能的间接经济价值进行估算,结果表明,该森林公园每年的总生态服务价值约为2.18亿元。

The quantitative studies on the ecosystem service function of forests have became a worldwide discussed issue in current days, due to the various forest-related environmental problems. From the perspective of the benefits of studying forest ecosystem, several methods （including market value,shade price and opportunity-cost method） are applied to assess the indirect economic value indexes such as water conservation, environmental purification, soil conservation, carbon fixation-oxygen released, species conservation and medical care of the ecosystem service function in Liuxi river national forest park. It is concluded that the total forest ecosystem service value of Liuxi river national forest park counts RMB 2.18 billion.
