山西小麦"纬海"气候区划与瓦尔特气候图的分析应用

针对前人在作物生态分区上普遍采用包括纬度和海拔在内尽可能多的气候因子进行分区研究所存在的繁琐缺点,根据山西南北纬度差异大、多山海拔差异大的地貌特点,仅以纬度和海拔为依据,进行了小麦"纬海"气候区划.结果表明,以纬度和海拔为依据的分区结果与前人多因子分区结果一致,纬度和海拔与温、光、水等7个气候因子之间存在密切的回归关系,除海拔与年降水量之间的决定系数外,决定系数均达到显著或极显著水平.在小麦"纬海"区划的基础上,又对每个区的主要气候特征采用瓦尔特水热关联图进行了补充分析,做到宏观分区简便、微观分析细微而特征突出,二者结合,有利于指导生产之用.

Analysis and Application of Climatic Divisions on"Latitude and Elevation" and Walter Climatic Chart of Wheat in Shanxi Province

In view of predecessors drawback existed in crop ecological divisions,which mostly adopting more climatic index besides latitude and elevation,and as many as possible factors analyze and make divisions,according to topographic feature of Shanxi that both latitude and elevation are greatly different,wheat "latitude and elevation" climatic divisions were conducted only based on the two factors.the result of divisions was in accordance with predecessors.Furthermore,this study also analyzed the R2 value of step...
