城市露水及其生态效应研究进展

城市露水是一种不可忽视的凝结水资源和湿度来源，其生态效应研究具有重要意义。本文就近年来城市露水及其生态效应研究进展进行了综述，并着重论述了在城市生态环境影响下城市露水量、城市露水化学生态、城市露水研究模型构建、城市露水生态模拟、城市露水收集方法等方面的研究状况。城市露水的形成明显受城市大气环境的影响，表现为城市露水量减少，城市露水中的一些离子浓度偏高，其化学成分与城市大气环境相关等。城市露水生态过程的模型构建和露水的生态模拟工作已经开展，但非常有限。另外．文章指出了城市露水及其生态效应研究存在的问题。提出了今后城市露水及其生态效应的研究方向。

Research progress in urban dew and its ecological effect

Urban dew is a non negligible condensed water resource and humidity origin. To research its ecological effect is of great significance. This paper summarized the recent research advances on urban dew and its ecological effect, with the focus on the collection of urban dew, its amount under effects of urban ecological environment, chemical ecology, and simulation and modeling. The formation of urban dew was obviously affected by urban ecological environment, e.g., the dew amount tended to decrease, and its chemical components were highly related to the urban atmospheric environment. Limited studies have been done for the simulation and modeling of urban dew. The issues about urban dew and its ecological effect research were listed, and some further research trends were prospected.
