摘要
基于云南30个县(市)1971-2010年气候要素资料,研究云南甘蔗主产区气候资源的分布特征。结果表明,云南蔗区年均日照、风速、气温、空气相对湿度、降水量、蒸发量和水汽压等气候要素在不同的县(市)间存较大的差异。一年中,日照最长的季节主要集中在冬春季节的12月、1月、2月、3月。降水量在各月中分布极不均衡,主要集中在夏秋季节,冬春少雨干旱,降水量呈现滇西偏多,滇南偏少的特点;30个县(市)的平均气温在一年中呈近似正态分布,夏季的3个月平均气温最高,四季中温度差异最大的是冬季,最小的是夏季;蒸发量较高的月份主要集中在春季和冬季的6个月。
Based on meteorological data collected from 30 counties in Yunnan province during 1971 and 2010,the climate distribution in sugarcane region in Yunnan province was studied. The result indicated that large differences were among 30 counties in climate indexes such as sunshine duration,wind speed,air temperature,relative humidity,precipitation,evaporation capacity and vapour pressure. The months of December,January,February and March in Spring and Winter were characterized with the longest sunshine hours. The value of precipitation significantly differed with months,which was higher in the seasons of Summer and Autumn,water stress occurred in seasons of Spring and Winter,the precipitation was higher in western Yunnan and less in the southern; Average values of temperature in 30 counties were approximately normal distributed,the highest temperature was the three months in Summer,the largest temperature difference among four seasons was Winter and the lowest in Summer; higher evaporation occurred in six months of Spring and Winter.
