摘要: 对青海省都兰县不同草地类型的生态系统服务价值和类型功能价值进行了尝试性的估算。结果表明,草地系统年平均价值为55.40亿元,各类草地提供的生态服务总价值为:温性荒漠16.50亿元〉温性草原13.64亿元〉高寒草甸11.60亿元〉高寒草原7.61亿元〉低地草甸6.05亿元。草地各类功能价值中,提供食物生产的经济价值仅是草地服务价值的一小部分,草地生态系统提供给人类服务最主要的是其潜在的间接生态功能和服务价值。

Abstract: The ecosystem service value and functional value of different grassland types in Dulan County of Qinghai Province were evaluated. The results showed that the annual average value of grassland system was 55.40 ×108 RMB yuan. And the total ecosystem service value provided by various kinds of grassland were as follows:temperate desert(16.50×108 RMB yuan) temperate grassland(13.64×108 RMB yuan) alpine meadow(11.60×108 RMB yuan) alpine grassland(7.61×108 RMB yuan) lowland meadow(6.05×108 RMB yuan) . Among various kinds of functional value of grassland,the economic value for providing the food production was only small part of grassland service value. The main service for human provided by grassland ecosystem was its potential indirect ecosystem function and service value.
