摘 要:对西双版纳山地逆温的考查结果表明:逆温顶层最高海拔上限达1800m,厚度600m—800m,最大逆温强度为3.7℃—3.8℃/100m,冬干季(11月—4月)逆温出现频率最高,达90%以上;逆温在山体坡面形成一个暖带,一般位于雾层顶部以上100m—200m范围内;越冬期间山区比坝区最低温度累计值高约700℃,日均温累计值高约230℃,日照每天多4h—5h;西双版纳山区按垂直高度分为三个气候带,海拔800m以下为北热带,800m—1800m为南亚热带。The results of study on inversion of mountains in Xishuangbanna reveal:The highest altitude of inversion is 1 800m.The thickness of inversion layer is 600m—800m.The most intensity of inversion is 3.7℃—3.8℃/100m.The frequency of inversion occurences is highest(over 90%)during winter and dry season(Nov.-Apr.).The inversion generally forms a warm zone between 100m-200m over top of fog layer on hill slope.The cumulative value of lowest temperature and adevage temperature of months are about 700℃ and 230℃,respectively and length of day is 4h-5h longer every day in mountain than in dike secter during winter season.Xishuangbanna is divided into three climatic zone on highness:north tropics,south subtropics and centre subtropics,and their altitude are below 800m,800m-1 800m,over 1 800m,respectively.
