中文摘要	对于降雨稀少的内陆干旱区,露水具有重要的生态学意义。在黑河中游的张掖市临泽县平川镇,于2008年6～9月利用人造面板法对露水进行了连续90 d的观测,发现:①只有当露水收集板的温度低于露点时,露水才能生成;②观测期间河岸带共生成露水52次,总生成量为4.26 mm,绿洲内共生成34次,总生成量为1.52 mm,戈壁共生成13次,总生成量为0.64 mm;③从旱季进入雨季,露水生成强度逐渐增大,雨季后期露水生成强度达到最大,此后又逐渐减小;④降雨有利于露水的生成,河岸带和绿洲内的露水生成受降雨影响显著,而只有当单次降水量达到一定阈值时戈壁才有露水生成;空气相对湿度、天气晴朗程度和风速也影响露水的生成。
英文摘要	Dew plays an important role in maintaining ecosystems in arid area.In order to study the dew formation,a series of observations on dew yield were conducted in Linze County,Zhangye City in the middle reaches of the Heihe River during the period from June to September 2008.The results are as follows:(1)Dew formed only when the board temperature was lower than dew point,and dew yield and occurred times were decreased with the increase of distance away from the Heihe River and of groundwater depth as well as the decrease of vegetation coverage;(2)Dew occurred for 52,34 and 13 times and the accumulated dew yields were 4.26 mm,1.52 mm and 0.63 mm in riparian zone,oasis and desert respectively during the period from June 20 to September 17,2008.There was also a temporal variation of dew yield at all three observation sties;(3)Dew intensity and average dew yield were increased from dry season to rainy season,and vice versa;and(4)It is found that rainfall is favorable for increasing dew yield at all three sites,and dew could form in desert only if previous rainfall exceeded a certain amount.Air relative humidity,weather and wind speed also affect dew formation.
