干岛效应

结果表明：土地利用变化引起的城市化使城市O3日均浓度升高，这与城市热岛效应、城市干岛效应以及地面风场的改变有关。

The results show the urbanization caused by land-use change increases daily average O3 concentrations in urban areas , which is related to urban heat island effect , urban dry island effect and the change of surface wind fields .

柳州市热岛效应与干岛效应

The Hot Island Effect and Dry Island Effect in Liuzhou City

市内年蒸发量比郊区增大250～480mm，表现出明显的城市干岛效应；

The annual evaporation capacity was 250 ￣ 480 mm higher in the urban district than in the suburb .

四个城市均存在干岛效应，但其强度的变化趋势不显著。

There are dry island effects in all four cities , though the trends are inconspicuous .

城市化导致的其它现象包括干岛效应、湿岛效应、混浊岛效应和雨岛效应。

Other phenomena resulting from urbanization include dry islands , wet islands , dark islands and rain islands in cities .

各城市四季的平均相对湿度也均呈现减少趋势，各城市的四季均存在干岛效应，且以不断增强的趋势为主导，但显著性程度不高。

The seasonal relative-humidity of four cities is decreasing , too . Though the significance is not high , there are dry island effects , and the intensities of them are increasing .

研究指出，由于广州近地层气温较高，加上城市热岛和干岛效应的影响，年平均雾日较少。

Study points out that there are fewer foggy days in Guangzhou per year because the temperature of surface layer is higher and because of the influences of urban heat island and dry island effects .
