| 摘 要： | 以能值理论为基础,以大巴山南坡雪宝山自然生态系统为研究对象,对自然生态系统的经济价值进行了研究.研究结果表明,雪宝山自然生态系统的经济价值约为2.64×107US＄/a,其中物质产品和生态服务(不含生物多样性)的经济价值分别为2.26×107US＄/a、3.67×106US＄/a,生物多样性的经济价值约为7.75×109US＄.这说明在评估自然生态系统的经济价值时,生态服务和生物多样性的经济价值不容忽视.

| Abstract: | This paper primarily studies on economical value of natural eco-system based on the emergy theory and focusing on the Xuebaoshan natural eco-system in the south slope of the Daba Mountain. The study shows that the value of Xuebaoshan natural eco-system is about 2.64×10~7US ＄/a, in which the value of substantial product and ecological service (excludes biological diversity) respectively 26×10~7 US ＄/a, 3.67 ×10~6 US ＄/a. The value of biological diversity is about 7.75×10~9 US ＄. The research shows that the value of ecological service and biological diversity should not be ignored, while valuating the economical value of natural eco-system. |
