    摘要:

    研究农田防护林生态系统服务功能的价值对于区域经济的发展和生态环境的保护具有重要意义。 运用市场价值法、机会成本法、影子价格法等, 对河南省2001和2005年农田防护林生态服务功能价值进行了核算。 结果表明, 2001和2005年农田防护林生态服务功能的总价值分别为1.04×1010元和1.46×1010元, 各项生态服务指标的价值顺序为:保育土壤>农田防护林防护>生物多样性保护>固碳释氧>净化空气; 生态服务的总价值年均增加1.53×109元, 其中保育土壤的价值增加最大为9.94×108元, 其余依次是农田防护林防护、生物多样性保护、林产品、固碳释氧、净化空气, 增加价值分别为3.01×108, 1.25×108, 7.00×107, 3.77×107, 7.79×105元。 因此, 农田防护林具有的生态服务功能价值是巨大的, 应该尽快建立生态服务市场补偿机制和完善生态服务功能价值评估方法, 促进农田防护林从生态型向生态经济型转变。

    Abstract:

    Evaluation of the farmland shelterbelt ecosystem service is of vital importance due to its practical application in regional economical development and ecological environment protection.In this case, farmland service function value of He′nan Province from 2001to 2005was evaluated by applying methods including market price, opportunity cost, and shadow price.Results showed that the total ecological service function value of the farmland in 2001and 2005were 1.04×1010 and 1.46×1010 yuan, respectively. The ecological service function index values followed such a decreasing order:soil protection>crops yield increment>biodi-versity protection>CO2fixation and O2release>air purification. The increment of total ecological servic was 1.53×109 yuan each year. The service of soil conservation increment value was the largest(9.94×108 yuan), followed by soil protection(3.01×108 yuan), crops yield increment(1.25×108 yuan), biodiversity protection(7.00×107 yuan), CO2 fixation and O2release(3.77×107 yuan), and air purification(7.79×105 yuan). Due to the fact that the ecological service function value of the shelterbelt is tremendous, it is sugges-ted that ecological service market compensation mechanisms and perfected ecological service function valuated should be established as early as possible, so as to extend the farmland from an ecological style to an ecologi-cal and economical style.
