| 摘 要： | 利用承德市和承德县1964~2007年逐月降水资料,采用趋势分析等统计分析方法,对比分析了承德市城区、城郊降水变化特征及其城市化的可能性影响.结果表明:近44 a来承德市城区、城郊年降水量均呈减少趋势;城市化进程加快时期城区、城郊年、季降水量的变化速率出现明显差异:城区年降水量呈增加趋势,而城郊则呈明显减少趋势;城区各季降水量相对城郊呈增加趋势:冬季、夏季城区、城郊降水量都是呈减少趋势,但是城区的减少速率要明显小于城郊;春季、秋季城区、城郊降水量均呈增加趋势,但城区增加趋势要明显大于城郊.城区年、月≥0.1 mm降水日数减少趋势小于城郊减少趋势;城区、城郊降水量的不同变化速率可能是由于城区空气污染较重和城区绿地和水面增多而导致空气湿度增加的影响. |

| Abstract: | Based on the historical rainfall data from 1964 to 2007,the possible effect of urbanization on precipitation was analyzed by statistics method for Chengde City of China.The results show that both the precipitation in Chengde urban and rural areas have decreased in recent 44 years.But in the quicker development period of urbanization,the annual and quarterly precipitation in urban and rural areas shows significant differences,that is,the urban annual precipitation has increased year by year,but the rural one... |
