摘要
运用生态系统服务价值评价方法,构建生态系统服务价值评价模型,评价若尔盖县草原生态综合治理示范工程项目区生态系统服务价值。结果表明,2012年若尔盖县退化草地改良示范工程项目区生态系统服务价值为36 339.07万元,其中物质生产价值和休闲娱乐价值1 785.97万元,仅占总生态服务价值的4.91%,而调节价值占到95.09%。若尔盖县退化草地改良示范工程项目区生态系统具有巨大的服务价值,而由经济上直接体现的物质产品生产价值和部分文化价值仅占小部分,在经济活动中被人们忽略的调节价值占生态系统服务价值较大比重。
In this study, the ecosystem service value evaluation method was employed to assess the ecological value of the Ruoergai grassland improvement project of 2012. The ecosystem service value of the project was estimated as 363.9577 billion RMB Yuan, and the material production value and leisure entertainment value was almost 17.8597 billion Yuan, which was accounted for only 4.91% of the total ecological service value, while the remaining value of the project, approximately, 95.09%, is adjustment value. The results indicated the project has great ecological service value, while the material production value and cultural value remain a very small part of its overall values.
