摘要
根据 195 1～ 1999年黑龙江省代表站的历年逐月的气温、降水量资料 ,用计算趋势系数的方法 ,研究了东北北部冷暖旱涝趋势的问题。结果指出 :进入 90年代 ,东北北部夏季气温变暖现象更加显著 ;但过渡季节气温变暖的趋势已经结束 ;旱涝趋势的变化比冷暖趋势的变化更为复杂 ,具有不同的季节特征和地域特征。
WT5BZ]The trends of temperature and precipitation in the north of the Northeast China are studied by using the trend coefficient based on the 1951～1999 data over 6 stations in Heilongjiang Province. Results show that during the recent 10 years there exist more significant ascent trend of summer temperature than that in the period 1951~1999 and the descending trends of spring and autumn temperature and that the precipitation trends have obvious difference in various seasons and various locations, exhibiting the complex characteristics.
