中文摘要: 本文利用1981—2014年江西91个气象观测站的地面气象观测资料和同期的分县晚稻产量资料,结合江西地区气候特点及晚稻生理特性,构建适用于江西地区晚稻降水、温度、日照及综合适宜度模型,并根据适宜度与产量的相关关系,确定气候适宜指数,建立基于气候适宜指数的江西晚稻产量动态预报模型,并对模型进行了回代检验及预报检验,从而实现对江西地区晚稻气候适宜度诊断及晚稻产量动态预报的目的。结果表明:模型的回代检验、产量丰歉趋势、产量动态预报检验的准确率均较高,能够满足业务的需要。
Abstract:By using the meteorological observation data from 91 weather stations in Jiangxi province during 1981-2014 and the late rice yield data of the corresponding time period, and combining physiological characteristics of late rice and climatic features of Jiangxi, the suitability models for temperature, precipitation and sunshine in the Jiangxi area are constructed. Moreover, according to the correlation between rice yield and suitability, the climate suitability index is determined. Then based on the index, the dynamic prediction model of the late rice in Jiangxi is constructed and tested so as to diagnose the climate suitability of the late rice in Jiangxi and to do dynamic prediction of the late rice yield. The results indicate that the method has high prediction accuracy of the bumper or poor harvest trend and the actual yield in the model test and forecasting test, and it could satisfy the needs of operational services.
