黑龙江省低温冷害区划研究

Study on the Chilling Damage Regionalization in Heilongjiang Province

农作物的低温冷害是黑龙江省主要的气象灾害之一,在20世纪60-70年代该省发生过几次严重的低温冷害,给农业生产造成了巨大的经济损失。利用极值出现重现期的计算,通过计算30年一遇的月最低气温,将黑龙江省低温冷害进行区划分析。结果表明:黑龙江省西南部和东部地区的齐齐哈尔、大庆、哈尔滨、牡丹江、鸡西、七台河、佳木斯、双鸭山等地区为轻微和轻度风险等级低温冷害区;黑龙江省中部地区伊春以北的呼玛、伊春、黑河、北安、五大连池、五营等地区气候温凉,温度较低,低温冷害频繁;黑龙江省北部大兴安岭地区是该省的极寒地区,常年温度较低,夏季较短,积温很少,热量条件严重不足。

The chilling damages of crops is one of the main meteorological disasters in heilongjiang province,including 60- 70 s of the 20 th century had several serious chilling damages,caused huge economic loss to agricultural production. In this paper,using extremum of return period,through the calculation of monthly minimum temperature of 30 years,will be chilling damages zoning analysis in heilongjiang province. The results show that the qiqihar,in heilongjiang province in the southwest and the east of daqing,Harbin,mudanjiang,jixi,qitaihe,jiamusi,shuangyashan area for slight and mild risk level chilling damages; Heilongjiang province yichun north central region of huma,yichun,heihe,soon,wudalianchi,camp five regions such as the climate cold,low temperature,low temperature chilling injury frequently; Greater hinggan mountains in northern area in heilongjiang province is in extremely cold area,low temperature all the year round,summer is shorter,little accumulated temperature and heat conditions.
