【摘要】 为了探讨本溪山区作物生长季地表及耕作层温度变化特征,利用本溪市草河口气象站1953-2014年作物生长季地表温度、耕层温度资料,运用数理统计分析等方法,分析了本溪山区作物生长季地温、耕层温度的变化趋势及特征。结果表明:本溪山区近62a来地表、耕作层温度呈随机性升温趋势变化,异常高温年21世纪初出现次数较多,异常低温年多出现在1996年以前;地表和浅层温度没有突变现象发生。更多还原

【Abstract】 In order to investigate change characteristics of temperature of ground surface and topsoil duringcrops growing season in Benxi mountainous area,based on the temperature data of ground surface and top-soil during crop growth season from 1953 to 2014 in caohekou meteorological station. By unitizing statis-tics analysis methods,temperature tendency and features of ground surface and topsoil during crop seasonswere analyzed. The results showed that temperature of ground surface and topsoil during crop growing sea-sons was stochastic warming trend,unusual high temperature climate occurred more times early 21 century,and extreme cold climate appeared before 1996;The ground surface and topsoil temperature was not muta-tion phenomenon.更多还原
