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.
