| 摘 要： | 为深入推进化肥减量行动，需要对已研发出的茶园化肥减施增效技术模式进行社会经济效果评价，筛选出适宜当地优先推广的技术模式。本研究采用文献综合研究法和专家咨询法，构建了一套适宜茶园化肥减施增效技术模式社会经济效果评价的指标体系，并运用基于专家意见多重相关性的灰色关联分析模型，对福建省闽东绿茶区5种化肥减施增效技术模式（模式1：施用专用肥模式；模式2：有机肥料替代部分化肥模式；模式3：施用脲甲醛复合肥新型肥料模式；模式4：施用生物炭基肥模式；模式5：地力改良与施生物炭结合模式）进行实证评价。结果表明：采用专家组多重相关性赋权法得到的最终权重中，技术特征指标权重最高，为36.52%，经济效益指标权重次之，为26.95%，社会效益指标权重为21.24%，管理指标权重最低，为15.29%； 5项技术模式的综合评价得分排序为模式2 （0.798 6） >模式1 （0.744 4） >模式4 （0.560 0） >模式3 （0.482 4） >模式5 （0.467 6）。研究表明，福建省闽东绿茶区适合优先推广有机肥料替代部分化肥技术模式，其次是专用肥模式，而其他三项技术模式有待进一步研究优化。

| Abstract: | To further promote the action of chemical fertilizer reduction, it is necessary to evaluate the socio-economic effects of the developed chemical fertilizer application reduction and efficiency improvement technical modes in tea gardens and select the appropriate and prioritized technical modes for application. The index system was constructed by comprehensive literature research and expert consultation method to evaluate the socio-economic effects of chemical fertilizer application reduction and efficiency improvement technical modes. The grey correlation analysis model based on multiple correlation of expert opinions was used to evaluate the socioeconomic effects of five chemical reduction and efficiency improvement technical modes(mode 1 is special fertilizer for tea, mode 2 is partial replacement of chemical fertilizer by organic fertilizer, mode 3 is new urea formaldehyde compound fertilizer, mode 4 is biocharbased fertilizer, and mode 5 is soil fertility improvement and biochar combination application) in the green tea gardens of eastern Fujian Province, China. Among the final weights obtained using the multiple correlation weighting method, the technical characteristics index had the highest weight at 36.52%, followed by the economic efficiency index weighting at 26.95% and the social efficiency index weighting at 21.24%; the lowest weight was the management index at 15.29%. The order of comprehensive evaluation scores of the five technical modes, from high to low, was as follows:mode 2(0.798 6) > mode 1(0.744 4) > mode 4(0.560 0) > mode 3(0.482 4) > mode 5(0.467 6). The results indicated that the green tea gardens in eastern Fujian is suitable for popularizing partial replacement of chemical fertilizer by organic fertilizer mode, followed by special fertilizer for tea mode, while other three technical modes need further research and optimization. |
