基于黑龙江省稻作区1961~2006年每年7月10日~8月10日逐日平均气温、5~9月逐月平均气温资料,采用气候统计方法,分析了延迟型冷害和障碍型冷害发生的规律和空间变化特征。结果表明:1961~2006年间,在黑龙江省稻作区,延迟型冷害发生频率由北向南减少,北部地区为延迟型冷害最易发生的地区,牡丹江半山区为延迟型冷害较易发生的地区,三江平原地区为延迟型冷害易发生的地区,松嫩平原地区为延迟型冷害轻发生地区。黑龙江省北部稻作区、东部稻作区和中部稻作区为障碍型冷害重发区,南部稻作区为中等发生区,西部稻作区为轻发区。
Based on the average daily temperature from July 10 to August 10 and the monthly average temperature data from May to September from 1961 to 2006 in Heilongjiang Province, the climatic statistic method was used to analyze the effects of delayed chilling injury and obstruction-based chilling injury Regularity and spatial variation. The results showed that the frequency of delayed chilling injury decreased from north to south in the rice planting area of Heilongjiang Province from 1961 to 2006, and the delayed chilling injury was most likely in the northern area. However, Sanjiang Plain is prone to delayed cold damage occurred in the region, the Songnen Plain as a delayed occurrence of cold damage light. Heilongjiang Province, the northern part of the rice area, the eastern part of the rice area and the middle of the rice area as a barrier-type chilling injury, southern rice area is the middle area, the western rice area light area.
