| 摘 要： | 以烟台市为例，通过对其湿度日变化和月变化规律的分析，总结出林地在垂直方向的增湿特点．选择了林地和旷野两种下垫面及三个能很好地代替不同季节天气的温差较明显的晴天，使用通风干湿计分别测量其在50，100，150，200cm高度处的大气相对湿度，并对测得的数据进行了对比分析，从而得出林地在垂直方向上增湿效果的变化规律．研究结果表明：城市绿岛对城市的热岛效应有一定的缓解作用，增湿效果显著．最后针对绿地对热岛效应的影响，提出了城市在发展中缓解热岛效应的一些措施．

| Abstract: | Taking Yantai City as an example, this paper discussed the humidity increasing feature of woodland in vertical direction through the analysis of daily and monthly variation regulation. By studying the wood land, field, two under lays and three unclouded days that could represent weather conditions of different seasons with obvious difference in temperature, the comparative humidity of atmosphere in the height of 50, 100, 150, 200 cm were measured by dry air ventilation instrument and comparative analysis were taken to analyze the measured data. Consequently, the changing rule of humidity increasing effect of woodland in vertical direction was summarized. The result showed that the urban green island could ease the urban heat island effect in a Way with notable humidity increasing effect. Finally, some proposals were given to weaken the heat island effect in the progress of city developing in allusion to the impact of green island on heat island effect. |
