文章摘要：为了筛选具有可持续性、适合鄱阳湖生态经济区的冬季绿色高效循环复合种植模式,通过2012年—2013年连续2年的田间定位试验,采用AHP法和综合指数法对鄱阳湖生态经济区5种稻田复种轮作模式（冬闲？稻？稻？冬闲？早稻？晚稻,绿肥？早稻？晚稻？油菜？玉米｜｜大豆？晚稻,油菜？玉米｜｜大豆？晚稻,蚕豆？早稻？甘薯｜｜玉米？蔬菜？甘蔗｜｜大豆,蔬菜？甘蔗｜｜大豆？绿肥？早稻？晚稻）的生态经济效益进行了综合评价。结果表明：按照晚稻价格比折算后,两年间各种植模式中蔬菜？甘蔗｜｜大豆种植模式的作物产量最高,其次是绿肥？早稻？晚稻,蚕豆？早稻？甘薯｜｜玉米的作物产量最低。生态经济效益综合评价表明,2012年各系统的综合效益指数大小排序依次为：蔬菜？甘蔗｜｜大豆〉油菜？玉米｜｜大豆？晚稻〉蚕豆？早稻？甘薯｜｜玉米〉绿肥？早稻？晚稻〉冬闲？早稻？晚稻,说明蔬菜？甘蔗｜｜大豆种植模式＂改稻为经＂,是能够带动稻田高产高效的种植模式,有利于农业生产的可持续发展。2013年经过稻田复种轮作后,各系统的综合效益指数表现为：绿肥？早稻？晚稻〉蔬菜？甘蔗｜｜大豆〉油菜？玉米｜｜大豆？晚稻〉蚕豆？早稻？甘薯｜｜玉米〉冬闲？早稻？晚稻,表明稻田冬种紫云英模式的绿肥？早稻？晚稻种植模式能兼顾三大效益,有利于农业生产的可持续发展。从两年的综合效益结果来看,蔬菜？甘蔗｜大豆→绿肥？早稻？晚稻模式能够带动稻田高产高效,能兼顾经济效益、生态效益和社会效益,可解决粮食安全和农业结构调整及农民增收等社会问题,而且对于冬季农业开发、自然资源的充分利用和农业生产的可持续发展也有极大的促进作用。综合来说,蔬菜？甘蔗｜｜大豆→绿肥？早稻？晚稻模式是适合我国鄱?

Abstr：The study aimed to build sustainable application of evaluation index systems and methods and to select sustainable rotation patterns of multi-cropping with high efficiency green in the Poyang Lake Eco-Economic Zone. We conducted two consecutive years of field experiment and used a comprehensive index method to evaluate ecological and economic benefits of different rotation patterns of multi-cropping system in paddy fields. Based on the price of late rice, the results showed that crop yield of vegetables-sugar cane｜｜soybean was the highest, followed by that of milk vetch-early rice-late rice and that of faba bean-early rice-sweet potato｜｜maize the lowest. In 2012, the order of the overall efficiency index was vegetables-sugar cane｜｜soybean 〉rapeseed-maize｜｜soybean-late rice 〉faba bean-early rice-sweet potato｜｜maize 〉milk vetch-early rice-late rice 〉winter fallow-early rice-late rice. This suggested that ‘vegetable-sugar cane｜｜soybean＇ intercropping pattern made rice production more economical as paddy fields supported high-yields with high efficiency. It was conducive for sustainable development of agricultural production. After multi-crop rotation, the order of the overall efficiency index for 2013 was milk vetch-early rice-late rice vegetables-sugar cane｜｜soybean rapeseed-maize｜｜soybean-late rice faba bean-early rice-sweet potato｜｜maize winter fallow-early rice-late rice. The ‘milk vetch-early rice-late rice＇ cropping pattern well accounted for the three main benefits conducive for sustainable agricultural production. Based on comprehensive benefits of the two-year experimental results, ‘vegetables-sugar cane｜｜soybean → milk vetch-rice-rice＇ cropping pattern had the highest efficiency and yield. It well accounted for social, ecological and
