摘　　要：不同的稻田水肥调控方式,将产生不同的经济、资源和环境效益。合理优化的稻田水肥调控方案应基于水稻节水、增产、减污3个方面的指标综合评价所得。以温黄平原单季稻为研究对象,以田间水肥调控为研究载体,建立基于水资源、环境和经济相统一的水稻水肥调控评价指标体系;同时利用熵权TOPSIS多目标决策模型,对浙东温黄平原单季水稻7种水肥调控方案进行优选。结果表明,浙东温黄平原地区"蓄雨薄露灌溉+3次施肥"模式最有利于水稻高产、节水、减污综合效益的发挥。Different schemes of regulating water and fertilizer in paddy fields will bring about different economic,resource and environmental benefits. Reasonable and optimized water and fertilizer regulation scheme of paddy fields should be relatively optimal in comprehensive evaluation combined with three indicators of high yield,water saving and pollution reduction. Taking the Wenhuang Plain in eastern Zhejiang Province as the research object and the field water and fertilizer regulation as the research carrier,this paper established an evaluation index system of water and fertilizer regulation based on the unification of water resources,environment and economy. Water resources mainly considered water use efficiency,economic indicator mainly considered grain yield,environment mainly considered total nitrogen and total phosphorus release. At the same time, using TOPSIS multi-objective decision-making model of entropy weight,seven water and fertilizer control schemes of single cropping rice in Wenhuang Plain of Eastern Zhejiang Province were optimized,and the optimal sequencing results showed that the "rainwater storage and dew irrigation + three times fertilization" mode in Wenhuang Plain of Eastern Zhejiang Province was most conducive to the comprehensive benefits of high yield,water saving,and pollution reduction in paddy rice.
