云南哈巴雪山自然保护区生物多样性经济价值评估

云南哈巴雪山自然保护区具有完整的森林生态系统和丰富的生物多样性,对保障长江下游的生态安全具有重要作用。依据2008年＂云南哈巴雪山自然保护区综合科学考察项目＂的野外调查资料,应用市场价格法、替代市场法等对保护区生物多样性经济价值进行评估,并对非使用价值进行了估算。结果表明,保护区生物多样性每年的经济总价值约为196 351.1万元,包括直接使用价值为21 224.7万元,间接使用价值169 158.2万元,非使用价值5 968.2万元。评估结果显示,保护区生物多样性所产生的生态服务及物种保育等间接价值远远超出其产生的直接使用价值,体现了生物多样性经济价值的外部经济特征。

Evaluation on the Economic Value of Biodiversity in Habaxueshan Nature Reserve, Yunnan, China

The Habaxueshan Nature Reserve located in the middle-upper reaches of the Changjiang River, and it＇ s well preserved natural forest ecosystems and rich biodiversity are important for ensuring the ecological security of lower reaches. The economic value of biodiversity was evaluated for the nature reserve using Conventional Market （CM） and Implicit Market （IM） Methods based on field data collected during the implementation of the compre- hensive scientific investigation in the nature reserve in 2008, and the non-use value of biodiversity also estimated. The result showed that ： the total economic value （TEV） of biodiversity up to 1. 963 511 billion Yuan annually, which include 212. 247 million Yuan of direct use value （DUV） , 1. 691 582 billion Yuan of the indirect use value （IUV） and 59. 682 million Yuan of the Non-use value （NUV）. The result also showed that the ecological service value of biodiversity exceeded it＇ s DUV greatly, and that indicated the characteristics of public good and external economic value of the biodiversity.
