摘要
本文通过对我国北方旱地农业区松嫩平原30个县(市)、40年完整的气象资料及农业产量资料的系统统计分析,得出松嫩平原40年来气候确有逐渐变暖的趋势,由于气候变暖,导致松嫩平原东部作物高产优势逐渐向南、北两个方向分化,玉米高产中心南移,麦豆高产中心北移,这是农业发展战略上需要注意的。据此,提出了该区农业综合发展的对策。
Based on systematic analysis of 40 years' complete meteorological data from 30 stations as well as the agricultural output information in Songnen Plain, one of the dry farming regions in Northern China,it was concluded that the climate in this plain was actually warming up,which lead to the split up of the high production areas to south and to north in the plain,that is the high yield area of corn gradually moving to south,and wheat and bean to north.Thus the changes in agricultural production should be paid attention to when working out strategies for agricultural development.
