近30年山西省冻融期地表温度变化规律及影响因素分析
Analyses on the Variation Regularity and Influencing Factors of Surface Temperature during Freeze-Thaw Period in Shanxi Province in Recent 30 Years
摘要
Abstract
[Purposes]Land surface temperature(LST)during freeze-thaw period has a great in-fluence on the growth of winter crops,water cycle,and surface vegetation evolution.Revealing the spatio-temporal variation of LST during freeze-thaw period and its response to influencing factors is significant for predicting future changes of LST.[Methods]By using R language,the meteorological data of 27 meteorological stations in Shanxi Province during freeze-thaw period were processed,and Mann-Kendall mutation tests were used to study the spatial-temporal variation of LST and its influ-encing factors during freeze-thaw period in Shanxi Province from 1990 to 2018.[Results]The results show that the surface temperature increased 0.608℃per ten years during the freeze-thaw period in Shanxi Province from 1990 to 2018,and changed abruptly in 2001,2004,and 2005 with rapid warm-ing.The spatial distribution of LST is higher in the southwest and lower in the northeast of Shaixi.Latitude and altitude are the main geographical factors influencing LST during freeze-thaw period.The correlation between precipitation and LST is positive in Northern Shanxi,while it is negative in Central Shanxi and Southern Shanxi.Sunshine hours have a negative effect on LST in Northern Shanxi,but a positive effect in Central Shanxi and Southern Shanxi.Wind speed,relative humidity,and air pressure have negative effect on LST.关键词
