摘要
为了研究东北地区主要气象因素变化规律,进而更好地对作物的品种布局进行指导,利用东北地区1961—2006年46年的97个气象站点的主要气象数据,利用反距离插值法分析了全年积温、降雨和辐射的区域分布规律,并分析了各气象要素的全年和作物生长季(5—9月)年际间变化规律和趋势。结果表明:东北地区全年积温、降雨和辐射分布具有明显的连续的地域特征,同时各气象要素间的年际变化存在一定的周期性。因此,充分利用东北地区主要气象因素的区域和时空分布规律,有效进行作物合理布局,保证粮食的高产和稳产具有重要意义。
In order to know the variation of the main climate factors in northeast China and better guide the arrangement of crop varieties,climate data of 97 climate stations for 46 years from 1961 to 2006 were analyzed.By using inverse distance interpolation method,the regional distribution of accumulated temperature,rainfall and radiation were analyzed,variation and trends among years of each climate factor in growing season（May to September） and the whole year were also analyzed.The results indicated that the distribution of accumulated temperature,rainfall and radiation in northeast China was consistent.Each climate factor was periodically changed between years.So,it was very important for high yield to take full advantage of regional and space-time rules of the main climate factors in northeast China and make reasonable distribution of crops.
