| 摘 要： | 利用黑龙江省81个气象观测站点43a的气象资料,以积温和降水作为主要因子,采用聚类分析的方法,重点分析了黑龙江省积温、降水量的时空分布和年代际变化。黑龙江省呈变暖趋势,43a来全省平均升温0.88℃,不同年代的平均气温异常各有其特点,20世纪90年代前气温异常年主要以异常偏冷年为主,20世纪90年代后气温异常年主要以异常偏暖年为主。聚类分析的结果将全省划分成5个种植带。

| Abstract: | By using 43 years observed data of 81 meteorological observed stations in Heilongjiang province, the paper emphatically analyzed space-time distribution and annual change feature of accumulated temperature and precipitation with cluster analysis. The result showed temperature increased year by year, mean temperature of Heilongjiang province promoted 0.88~C, abnormal change feature varied from years. Abnormal year was mainly abnormal cold before the 1990s; abnormal year was mainly abnormal warm after the 1990s. The province was divided five planting areas with cluster analysis method. |
