中文摘要：

在全球变化环境压力下，非干旱地区露水研究对露水沉降规律的认识及其生态效应研究具有重要意义。文中以非干旱地区为研究区域，采用布片法对晴朗夜间的露水进行了研究。结果表明，各个季节的露水发生频率和露水凝结量明显受季节变化的影响，不同季节露水发生和凝结各不相同。秋季露水发生频率较高，达80％，春季露水频率较小，不到30％。就平均每晚露水量看，夏季和秋季无明显差异，但都显著高于冬季和春季。夜间最大露水量发生在秋冬季，大约0．23mm。此外，下垫面对露水具有重要影响，不同下垫面上凝结的露水量不同，有植被覆盖的下垫面在夏秋季节凝结的露水量显著高于混凝土上凝结的露水量。研究结果说明，在环境管理中，应增加地表植被的覆盖，促进露水凝结。

英文摘要：

The cloth-plate method was used to collect dew in clear night in Conghua City, where is not an arid or semi-arid area. Results show that dew frequency and dew amount are influenced by seasons evidently, with a different dew pattern and quantity in each season. The relatively higher dew frequency was recorded in autumn with values as high as 80 %, while the lower one was found in spring with values no more than 30 %. There was no significant variation between mean dew amount in summer and autumn, but they were both significantly higher than those in winter and spring respectively. The maximum dew amount was recorded in autumn and winter, about 0.23mm. In addition, the substrate has great influence on the formation of dew. The dew values observed on the ground covered by vegetation were significantly higher than those in concrete road. Results suggest that the dew condensation will increase if vegetation coverage is increased during the environment management.
