摘 要:在国内外森林生态系统服务价值研究的基础上,运用市场价值法,机会成本法和影子价格法等对黄淮海平原2001和2005年农田防护林生态服务的价值进行研究。主要内容包括农田防护林的活立木蓄积的价值、农田防护林的防护功能、净化空气、固碳供氧、保育土壤以及生物多样性保护功能的价值。结果表明:2001~2005年农田防护林生态服务的价值年均增加30.11亿元,充分显示了农田防护林生态服务的重要性。因此,认为我国应该建立农田防护林生态服务系统的价值评价指标体系,进一步深入研究农田防护林的生态服务价值。This paper studies on ecosystem services for farm shelter-forests in Huang Huai Hai Plain in 2001 and 2005 based on a review of ecosystem services valuation summary at homeabroad and abroad.The ecosystem services evaluation methods were adopted and the farm shelter-forests ecosystem services in Huang Huai Hai Plain in 2001 and 2005 were classified into direct and indirect benefits.Direct benefits of ecosystem services included the income from timber;indirect ecosystem services of ecosystem services were the principal part of its environment protection function and consisted of protect functions,air purification,carbon fixation and oxygen production,soil conservation and biodiversity conservation.According to calculating,the results indicated that their ecosystem services increased 3.011 billion Yuan annually in average from 2001 to 2005.The results also showed that our country should set up a series of assessment index systems suitable for farm shelter-forests ecosystem services,by which their studies would move forward.
