中国年平均气温图lllVVen逆温(in~叩)气温随高度升高而递增的垂直分布。通常,大气温度是随高度增加而降低的。但在地面辐射冷却、暖空气流向冷地面、近地层扰动等情况下,能使低层空气温度低于上部,气温在垂直方向上一反正常的分布情况、故名。逆温类型有辐射逆温、下沉逆温、湍流逆温、平流逆温和锋面逆温等。温度随高度增加的气层称逆温层。逆温层内,空气密度随高度而迅速减小。逆温层层结稳定,具有抑制对流和湍流的作用,极不利于大气扩散,使大气污染物浓度增加。,但是在山区垂直带上经常出现的逆温层(又称暖带),是优越的农业生态环境和气候资源。以辐射地形混合型为主的山地逆温通常出现在晴朗无风的夜间。日落前后开始形成。清晨最低温出现前后,逆温层厚度达到最大值,逆温层顶一般位于山体相对高度的l/3、1/4处。日出后逆温消失。中国亚热带山地是逆温高发区,一些较大山区逆温发生概率全年在20%以上,最高可达65.8%;秋冬季平均在30%以上,其中冬季平均在40%以上,最高可达卯%。,逆温强度一般在3℃/loo米以下,最大可达8~9℃/loo米。多数山体的逆温层厚度为2(X)~月田米。山地逆温层有利于延长生长期;提高农产品产量和质量;减轻箱冻害;提高喜温作恤的种植上限;减轻或避免越冬作物及多年生经济果木林冻害。掌握山地逆温资源分布规律进行立体农业布局,对发挥山区农业生产潜力有重要作用。(张建敏)
