四川省森林生态系统对野生珍稀濒危动物的保护价值计量研究

论文以异地保护成本替代法计算森林生态系统对濒危野生动物的保护价值。栖息于四川省森林生境的濒危野生动物需要生存下去所必需的食物、水、居住环境等一切生存条件完全由人为提供、人为创造和维持的成本就是四川省森林生态系统保护这些野生动物的价值。论文以动物园饲养动物的基本成本作为濒危野生动物异地保护的核算依据,得到四川省森林生态系统对野生珍稀濒危动物的保护价值为15.45×10⁸元/a。

Estimating the Values of Forest Ecosystems in Conserving Rare and Endangered Animals in Sichuan Province

The value of ecosystems in conserving biodiversity, especially the rare and endangered animals (REAs), is an important component in the overall ecosystem values. However, directly estimating the values of ecosystem has been difficult and sometimes misleading. Thus, the current study used the costs of ex-situ conservation of the REAs to evaluate the value of forest ecosystems in protection the REAs in Sichuan Province to assist policy making in forest conservation and management. The approach is based on the alternative cost method, namely taking away the habitats provided by the forests, all the rare and endangered animals inhabited should be conserved by providing them with land, food, water, and other necessities. The costs of the ex-situ conservation represent the value of the forest ecosystems in protecting the REAs. According to the “basic” costs of individual animals in the Chengdu Zoo, we found that the total value of the forest ecosystems in protecting the REAs in Sichuan is 15.45×10⁸ yuan in 2012.
