摘要: 文中参照Constaza等提出的方法,在对草地生态系统服务价格根据其生物量订正的基础上,逐项估计了各类草地生态系统的各项生态系统服务价值,得出全国草地生态系统每年的服务价值为14979×108US$。其中扰乱管理价值占1607%,水管理和水供应价值占1444%,侵蚀控制和沉积保存价值占908%,废物处理价值占4203%,授粉价值占783%,生物控制价值占72%,食物和原材料生产价值占2226%,娱乐和文化价值占578%,其它如气体管理价值、土壤形成价值和栖息地价值低于5%。受各类草地生物群落分布广度和单位面积生态服务功能强弱的综合影响,各类草地的生态服务价值贡献率有很大差异,其中,沼泽类对草地生态系统总服务价值的贡献率为5234%。温性草原类、热性草丛类、热性灌草丛类、低地草甸类和高寒草甸类对总服务价值的贡献分别在503%~774%之间,其余类型的草地生态服务价值贡献率在5%以下。

Abstract: It is of great significance to estimate ecosystem services value By using method proposed by Constaza et al (1997) and others,this paper calculated the unit area value of rangeland ecosystem services in terms of its biomass in China The results showed that the total value of annual rangeland ecosystem services in China was about US$149.79 billion,among which,the percentage of gas regulation took up 2 66%,that of disturbance regulation accounted for 16 07%,water regulation and water supply 14 44%,erosion control and sediment retention 9 08%,soil formation 0 31%,waste treatment 42 03%,pollination 7 83%,biological control 7 2%,refugia 1 08%,food production and raw material 22 26%,and recreation and culture 5 78% Owing to the integrated effects of biological communities distribution and ecosystem function of unit area,the contribution ratio of ecosystem services of various rangeland types different greatly The contribution ratio of marsh type made up 52 34%,the total contribution ratio of temperate steppe type,tropical herbosa type,tropical shrub herbosa type,lowland meadow type and alpine meadow type varied in the range from 5 03% to 7 74%,that of others types below 5%
