东北农牧交错区生态系统服务功能价值评估研究

Assessment on ecosystem services of the farming-pasture zone in Northeast China

运用市场价值法、替代工程法、影子价格法等方法对东北农牧交错区生态系统服务功能的价值进行了评估;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生态环境恶劣,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。

Argo-ecosystem is very important to our human being, but the fact is we know very less about its ecosystem service. So this study selects the farming-pasture zone in Northeast China and use different methods（such as market value, substitution engineering, shadow price）to calculate its value. The result shows agro-ecosystem provides great ecological service to its economic productivity, and provides more service than its production service.
