摘要: 运用市场价值法、替代工程法、影子价格法和机会成本法等方法对内蒙古阴山北麓风蚀沙化区农业生态系统服务功能的价值进行了经济评估。结果表明,该地区农业生态系统总的服务价值为465453810万元,其中产品服务价值为29874.1万元(占0.06%),水土保持价值为4570284.2万元(占9.7%),涵养水源价值为42802.6万元(占0.09%),气候调节价值为393411.8万元(占0.84%),营养物质循环价值为41910673.9万元(占89.27%),从服务功能的价值比例来看,系统的环境服务价值要远远大于其产品服务的价值,表明该地区农业生产水平落后,同时也体现了在当地环境恶劣,农业经营粗放的前提下,系统环境服务价值是维系其不稳定农业生产的基础.

Abstract: The economic evaluation on ecosystem services has become a frontier of ecological studies.The concept and economic values of ecosystem services have been thoroughly discussed over the past decade, mostly on natural ecosystems and less on agroecosystems.In this paper,the agroecosystem services and their economic value were estimated in wind-erosion region near the northern foot of Yinshan mountain in Inner Mongolia.The results showed that the total economic value in RMB of agroecosystem services in this area was about 465.45 billion yuan.In this amount,estimations for production service amounted to 0.06%,for soil protection to 9.7%,for water holding capacity to 0.09%,for climate regulation to 0.84% and for nutrient recycle to 89.27%.
