摘要
利用1961—2008年云南省124站气温观测资料,经过地形订正后,形成1km×1km的细网格点数据。在此基础上,开展了云南省细网格气候区划及气候代表站选取的研究。结果表明,云南可划分为高原气候带、温带、北亚热带、中亚热带、南亚热带和北热带等6个气候带,所占面积分别为3.32×104、3.65×104、15.65×104、6.82×104、8.66×104和1.31×104km2;高原气候带分布在滇西北3000m以上高海拔地区,温带主要分布在滇东北和滇西北海拔高度为2200～3000m的地区,北亚热带主要分布在滇中、滇西、滇南高海拔地区和滇北低海拔地区,中亚热带主要分布在滇中、滇东南和滇西南海拔较高的地区,南亚热带主要分布在滇南和河谷地区,北热带主要分布在滇南和海拔较低的河谷地区;各气候带分布与地形和纬度相关联,地形因素比行政区域更能体现气候特征;通过站点序列与气候带序列趋势变化一致性和偏离程度的统计分析,所选气候代表站与相应气候带序列变化非常一致,能够较好地代表云南各气候带变化特征。
By using the temperature observation data of 124 stations in Yunnan Province during 1961—2008,the 1 km×1 km fine-grid temperature data was obtained after the terrain correction.The study on the climate division based on the fine mesh data and the selection of representative climate stations in Yunnan Province was carried out.The results show that there are six climate zones in Yunnan Province,namely,plateau climate zone,temperate zone,north subtropical zone,middle subtropical zone,south subtropical zone and north tropic zone.Each of them occupies an area of 3.32,3.65,15.65,6.82,8.66 and 1.31 ten-thousand square kilometers respectively.The plateau climate zone is located in the high altitude area over 3 000 m in northwest of Yunnan Province.The temperate zone is mainly located in the area with altitude of 2 200～3 000 m in the northeast and northwest of Yunnan Province.The north subtropical zone is mainly located in the high altitude area in the middle,west and south and the low altitude area in the north of Yunnan Province.The middle subtropical zone mainly lies in the relatively high altitude area in the middle,southeast and southwest of Yunnan Province.The south subtropical zone mainly lies in the south area of Yunnan Province and the stream valley area.The north tropic zone is mainly located in the south area of Yunnan Province and the lower altitude stream valley area.Distribution of each climate zone is related with the terrain and the latitude.Compared with administrative region,the terrain feature better embodies climate characteristics of different climate zones.Through statistical analysis on consistency and deviation of the sequence of the stations and the climatic zone,representative climate stations are selected.They can better reflect the characteristics of each climate zone of Yunnan Province
