2种模式下2001—2016年郯城主要粮食作物气象适宜度对比分析
摘要[目的]构建简单适用的粮食作物气象适宜度计算模型。[方法]利用2001”2016年山东省郯城县逐日气象资料和主要粮食作物（水稻、小麦、玉米）发育期及单产资料，采用近年研究中主流气象适宜度模型和该研究自称的主推模型2种模式，分别计算了2001”2016年郯城境内3种主要粮食作物的气象条件适宜度，并对比分析了2种模式下气象条件适宜度与气象产量的相关性。[结果]主流模型较主推模型计算出的气象适宜度普遍偏低；水稻生长发育气象适宜度计算中，主推模型表现较好；小麦生长发育气象适宜度计算中，2种模式均表现欠佳；玉米生长发育气象适宜度计算中，主流模型表现较好。[结论]该研究可为相关研究提供借鉴参考。

Abstract[Objective] The research aimed to build a simple applicable grain crop meteorological suitability calculation model. [Method]Based on the daily meteorological data and the developmental periods and yield data of major grain crops （rice， wheat and corn） in Tancheng County of Shandong Province from 2001 to 2016，using the two models of the mainstream meteorological suitability model in recent years and the model recommended by this study， the suitability of meteorological conditions for three major grain crops in Tancheng prefecture during 2001-2016 was respectively calculated，and the correlation between meteorological conditions suitability and meteorological yield under two modes was analyzed and compared.[Result]The meteorological suitability in the main model was generally smaller compared with the model recommended by this study； In the calculation of rice growth and development meteorological suitability， the model recommended by this study was better；In the calculation model of wheat growth and development meteorological suitability，both models performed poorly； In the calculation...
