| 摘 要： | 利用1970-2012年廊坊市逐日降水观测资料和城市化发展资料,研究了城市化进程对廊坊地区降水特征的影响。结果表明：随着城市化的发展廊坊地区年降水量和汛期降水量分布格局发生明显改变,降水向城市化发展迅速的地区集中;城市化对降水的影响随降水强度增大而逐渐显著,且城市化发展愈迅速影响愈大;城市化使城区的降水量趋于集中,郊区的降水量趋于均化,这种趋势在未来一段时间内将持续。

| Abstract: | Based on the daily precipitation data during 1970-2012 and the population and GDP data in Langfang,the influence of urbanization on the precipitation characteristics was studied.The results showed that the spatial distribution pattern of annual and flood seasonal precipitation had obvious changes in Langfang with the development of urbanization,and the rainfall focused on the rapid urbanization areas.The effect of urbanization on precipitation was more obvious with the increase of rainfall intensity and the rapid development of urbanization.Furthermore,the urbanization made the precipitation concentrated on urban areas and homogenized on suburban areas,this trend will continue for some time. |
