| 摘 要： | 通过对位于干旱荒漠区的张掖国家气候观象台土壤温湿度、土壤温度梯度、土壤导热率分析,结果表明:该地区土壤温度年变化、日变化较明显,受辐射变化影响大;土壤湿度年变化、日变化不明显,受降水影响较大.不管冬、春、夏季,土壤温度在晴天日变化较明显,但在雨(雪)天,日变化不明显.土壤湿度在晴天和雨(雪)天日变化均不明显,对降水有一...

| Abstract: | The soil temperature,humidity,temperature gradient and thermal conductivity in Zhangye National Climate Observatory were analyzed.The annual and daily variation of soil temperature were influenced by radiation variation obviously,the annual and daily soil humidity influenced by precipitation were not obvious.The daily variation of soil temperature was obvious in sunny day regardless in winter spring and summer,but not obvious in rain(snow) day.The daily variation of soil humidity was not obvious in sunny an... |
