摘要： 生态保护的成本是生态补偿标准的核心组成部分,一般由直接成本、机会成本和发展成本构成。本文以羌塘自然保护区涉及的那曲地区为例,采用恢复成本法和机会成本法对牧民参与野生动物保护的直接成本和机会成本进行了核算。研究过程中,借用中国草地承载力评估中的标准羊单位,把草地生态系统、草食性野生动物和价值评估有机地联系起来,为草原地区野生动物保护的生态补偿提供了一个有效的评估工具。评估结果表明,那曲地区牧民参与野生动物保护的成本是每年5.69亿元,其中直接成本是1.19亿元,机会成本是4.5亿元,机会成本占总成本的79%。机会成本是由于草食性野生动物的啃食与踩踏导致草场必须禁牧致使牧民放弃的经济收入。显然,羌塘自然保护区草食性野生动物对草场的损害构成了生态补偿的主体。如果按照那曲地区中度以上退化草地的面积计算,则牧民保护野生动物的单位面积成本是每年57元,按照那曲地区人口计算,参与野生动物保护的人均成本是每年1482元。这一结果并不等于生态补偿标准,但可以作为补偿标准的低限。

Abstract: The cost of ecological and environmental protection is a core part of ecological compensation standards and consists of direct costs, opportunity costs and development. This paper uses Naqu, a section of the Chang Tang Nature Reserve, Tibet as a case study to assess direct and opportunity costs of wildlife conservation to herdsmen. A standard sheep unit has been established for determining the animal carrying capacity of grasslands across China, and we used this to convert wild animals into standard sheep units. This approach links the grassland ecosystem, herbivorous wild animals and their valuation together. Our results show that the total cost of wildlife conservation reached 5.69 billion Chinese Yuan (CNY). The opportunity cost was 4.5 billion CNY, accounting for 79% and direct cost. The biggest economic loss to herdsmen was the opportunity cost in Chang Tang Nature Reserve and means that herdsmen have to give up economic income from livestock husbandry when grazing is banned. Opportunity cost assessment is integral to establishing ecological compensation. The average value of wildlife conservation was 1482 CNY per capita and 57 CNY per hectare according to population and the area of moderately and seriously degraded grassland. The period of ecological compensation should last five to ten years after grazing is banned.
