立足于生态学、经济学、会计学原理与方法,运用市场价值法、机会成本法、影子价格法等,以2005年数据为基准,对辽宁省农田防护林生态系统服务价值进行核算。结果表明:辽宁省农田防护林生态服务功能的总价值为33.01亿元,各项生态服务指标的价值由大到小的顺序为:减弱蒸发、减灾防护、保育土壤、固碳释氧、净化空气,其中减弱蒸发和减灾防护价值占总服务价值的60.23%。
Based on ecology, economics and accounting principles and methods, the farmland ecosystem function value of Liaon-ing Province was evaluated by market price, opportunity cost and shadow price.In 2005, the total ecological service func-tion value of the farmland ecosystem in the province was 3.301 billion Yuan, and the ecological service function index val-ue was in the order of reducing evaporation＆gt;preventing and reducing natural disasters＆gt;soil conservation＆gt;carbon fixation and oxygen release＆gt;air purification.The service values of reducing evaporation, and preventing and reducing natural disasters account for 60 .23%.
