抚顺地区热量条件及低温冷害成因浅析

Fushun Heat Condition and Genetic Analysis of Chilling Damage

采用一元回归方程、滑动平均等统计学方法,对抚顺地区新宾、清原、章党3个气象站48年的平均气温年代、季变化特征,≥30℃高温日数、连续日数,初、终霜日数、无霜期日数,日平均气温稳定通过0、5、10℃积温的空间分布、持续日数以及低温冷害变化规律进行分析。结果表明,抚顺地区气温变暖趋势明显,年平均气温增温率为0.29℃/10a,≥30℃高温日数增加速率为2 d/10a,无霜期增幅为3d/10a,各界限温度增温幅度为94～164℃.d/10a。低温冷害以延迟型冷害为主,受低温出现后期气温回暖较快影响,致灾比例较小。

By using the regression equation,moving average and statistical methods in Fushun Xinbin,Kiyohara,Party Chapter from three meteorological stations in 48 years time,seasonal change characteristics of mean temperature,≥ 30 ℃ high temperature days,consecutive number of days,the early frost,frost-free period,the number of days,the daily average temperature stability through at 0 ℃,5 ℃,10 ℃ accumulated temperature spatial distribution,duration and low temperature change were analyzed.The results showed that： Fushun regional warming trend is clear,the annual average temperature of temperature increasing rate of 0.29/10a,≥ 30 ℃high temperature days every 10A increased 2D,frost-free period every 10A added 3D,the limits of temperature of each 10A temperature 94-164 ℃.Chilling injury in delayed type chilling injury,affected by hypothermia appear late temperatures are warmer faster effect,a smaller proportion of disaster.
