1961～2023年阜新地区农业气候资源变化特征分析
Variation Characteristics of Agricultural Climate Resource in Fuxin from 1961 to 2023
摘要
Abstract
Using daily meteorological data from two national basic meteorological stations in Fuxin from 1961 to 2023,The spatial-temporal variation characteristics of climatic are analyzed by using climate tendency,moving average and Mann-Kendall mutation test.The results show that in recent 63 years,the heat resources in Fuxin area have obviously increased,with the annual average temperature increasing by 0.26℃/10a,and the accumulated temperature at≥10℃increasing by 64.18(℃·d)/10a.The first day of stable passing through agriculture critical temperatures of 0℃,5℃,10℃,15℃and 20℃is advanced,and the final day is delayed,and the duration days are increased.The precipitation resources in Fuxin area do not have signifi-cantly increased,with an increase of 7.43 mm/10a.The sunshine resources decreased obviously,with a de-crease of 46.02 h/10a.In terms of spatial distribution,the heat resources and precipitation resources in Zhan-gwu County have increased significantly compared with Fuxin County.Sunshine resources are significantly re-duced in Zhangwu County than in Fuxin County.The annual average temperature suddenly changed from less to more in 1994,and then increased by 0.7℃.The accumulated temperature of≥10℃changed suddenly in 1997,and then increased by 252℃·d.There is no obvious mutation in annual precipitation;The annual av-erage sunshine hours changed suddenly in 1979,and then decreased by 204.5 h.关键词
