摘要:

研究过去有关广西气候区划的成果和1961~2000年气候整编资料,以稳定通过10℃期间的积温6900℃和8000℃等积温线作为划分气候带的指标,以2~4月降水量300mm,200mm等雨量线和1月平均气温9℃等温线作为划分气候区的指标,制作新的广西气候区划,并评述各气候区的气候特点。广西气候划分为3个气候带,9个气候区。3个气候带自北向南分为中亚热带、南亚热带和北热带,各气候区命名为:中亚热带东北部气候区、中亚热带北部气候区、中亚热带东南部气候区、中亚热带桂中气候区、中亚热带西南部气候区、南亚热带东部气候区、南亚热带中部气候区、南亚热带西部气候区、沿海北热带气候区。

Abstract:

Based on the previous related researches on the climate regionalization of Guangxi and the multi-year mean data of 1961to 2000, a new climate division of Guangxi is proposed by using three indices:the accumulated temperature contours of 6900℃ and 8000℃ at temperature higher than 10℃, the 300mm and 200mm rainfall contours from February to April and the temperature contour of 9℃ on average in January.Guangxi area is divided into three climate zones and nine climate districts in the present climate regionalization.Three climate zones are mid-subtropical zone, south-subtropical and north-tropical complied with the north to south.The nine climate districts are mid-subtropical northeast climate district, mid-subtropical north climate district, mid-subtropical southeast climate district, mid-subtropical middle-guangxi climate district, mid-subtropical southwest climate district, south-subtropical east climate district, south-subtropical middle climate district, south-subtropical west climate district, north-tropical coastal climate district.
