摘　　要：调水工程防护林具有固碳释氧、固土保肥、休闲游憩等生态功能,可产生显著的生态环境效益。基于Costanza和MA理论,全面系统地构建了涵盖15项指标的调水工程防护林生态环境效益评估指标体系,具体分析了价值量评估法的应用,并以南水北调中线郑州段干渠防护林为典型实例进行分析。结果显示,该段防护林年均生态环境效益为5 367.67万元/a,年均成本为805.42万元/a,年均生态环境净效益为4 562.25万元/a。其中,净化空气、固土和调节水量是中线郑州段干渠防护林的热点生态功能,贡献率分别为19.22%、12.36%和12.13%。Water diversion project shelterbelt has the ecological functions of carbon fixation and oxygen release, soil fixation and fertilizer conservation, leisure and recreation, and can produce remarkable ecological and environmental benefits. Based on the theory of Costanza and MA, the evaluation index system of ecological and environmental benefit of shelterbelt for water division project covering 15 indexes was constructed comprehensively and systematically. The application of value evaluation method was analyzed in detail, and the shelterbelt of main canal of Zhengzhou section of middle line of South-to-north Water Division Project was taken as a typical example. The results showed that the annual ecological and environmental benefit of the shelterbelt was 53,676,700 yuan/a, the annual cost was 8,054,200 yuan/a, and the annual net ecological and environmental benefit was 4,562,500 yuan/a. Among them, the air purification, soil fixation and water regulation are the hot ecological functions of shelterbelt in Zhengzhou section of middle line, rate of contribution are 19.22%, 12.36% and 12.13%, respectively.
