摘要： 为了减少连阴雨灾害对主要粮食作物生长发育及产量的影响，根据农田水分平衡原理，基于渍涝天数，渍涝影响程度和日照构建了连阴雨灾害指数模型，系统分析了不同生育期连阴雨灾害的发生规律以及对作物的影响。结果表明，连阴雨灾害的出现频率是每两年出现1次，影响小麦1~2个生育期，影响水稻2~3个生育期；主要发生时段是小麦拔节期，水稻的分蘖和移栽期；镇江的小麦仅有10%的年份，水稻仅有8%的年份完全未受连阴雨灾害的影响；小麦12~25%相对气象产量的波动，水稻11~24%相对气象产量的波动是由连阴雨灾害造成。为了科学防御连阴雨灾害的影响，利用连阴雨灾害指数模型，及时发布监测预警信息，为灾害的防御提供参考信息。

Abstract: The paper aims to reduce the impact of continuous rain disasters on the growth and yield of the main food crops， Based on the farmland water balance principle，a continuous rain disasters index model was constructed on waterlogging duration，the level of drought-waterlogging and the degree of sunshine． It analyzes the occurrence law of Zhenjiang continuous rain disasters and the impact on the growth of the main food crops． The results showed that， the occurrence frequency of continuous rain disaster is 1 times every two years， the impact of 1~2 on wheat growth period，and the effect of 2~3 on Rice; it mainly occurred in wheat jointing stage，rice tillering and transplanting stage; Only 10% of the wheat and 8% of the rice in the years was not affected by the rain disaster; The relative meteorological yield fluctuation of 12~25% in wheat and 11~24% in rice was caused by continuous rain disaster． In order to scientifically prevent the influence of continuous rain disaster， a continuous rain disaster index model was built and the monitoring and early warning information was published to provide reference for prevention．
