摘　　要：优化南方双季稻田复种方式,有利于增加农田生物多样性和生态服务功能趋于完善。通过3年的大田定位试验,对比研究"冬季休闲-双季稻"和"冬季作物-双季稻种植"模式下水稻生态服务功能价值的优劣,探讨不同复种模式对双季稻田生态服务功能的影响。结果表明:(1)"冬季作物-双季稻"的复种模式比冬季休闲模式的生态服务功能优越,在农产品供给、气体调节、净化空气、水分保持功能价值方面都有明显优势。(2)"冬季作物-双季稻"复种模式的服务总价值均大于冬季休闲复种模式,其中冬季种植蚕豆模式(F处理)的服务总价值最高。Optimization of multiple cropping patterns is advantageous to the perfection of farmland biodiversity and ecological service functions in southern China double-cropping paddy field.Field experiments were conducted in 2008-2011 to compare the ecological service functions between winter fallow and winter cropping in double cropping rice,and analyze the effects of the different winter crop planting models on ecology service functions.The main results were as follows：（1）Compared with the winter fallow-double cropping rice system,all winter crops-double cropping rice patterns were superior in ecological service functions,and showed superiority in the agricultural production supply,gas regulation,air purification and water conservation.（2）The values of agro-ecosystem ecological services in all winter crops-double cropping rice systems were more than that of the winter fallow system,and the winter faba bean-double cropping rice system had the biggest values of agro-ecosystem ecological services among all the cropping systems.
