抚顺地区热量条件及低温冷害成因浅析

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。

Fushun Heat Condition and Genetic Analysis of Chilling Damage

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.
