腰井子自然保护区草原生态系统服务价值估算

THE ECONOMIC EVALUATION OF STEPPE ECOSYSTEM SERVICES IN YAOJINGZI NATURE RESERVE

参照Costanza等提出的生态系统服务价值评估方法,在腰井子自然保护区草原生物量订正基础上,逐项估算了该区生态系统实物生产、CO2固定、O2释放、气体调节、有机物质的生产、土壤形成与保持、营养元素循环、调节水循环与涵养水源、废物处理、干扰调节、娱乐、文化等直接、间接使用价值及非使用价值。结果表明,腰井子保护区草原生态系统年服务价值可达26.42×108元。

By using methods proposed by Constaza et al and others, this paper revises the economic value of steppe ecosystem services in Yaojingzi nature reserve according to its biomass. Some sorts of direct and indirect using values are calculated ,such as food production and raw material, CO2 reserve, O2 release, water regulation and water supply, erosion control and sediment retention, soil formation, waste treatment, pollination, biological control, refugia, recreation and culture. The result shows that the annual value of steppe ecosystem services in this area is 26.42 × 10^8 RMB/a.
