摘　　要：利用1967—2016年徐州3个国家基本气象站徐州站、睢宁站、邳州站的日降水观测数据,讨论徐州地区降水变化特征及城市发展对其影响,得到如下结论,(1)徐州城市化发展速度较快,发展效果较好,地区经济增长平稳;产业结构积极转型,产业结构布局较合理。(2)徐州市区与睢宁的年降水量有小幅度增加,邳州呈现减少趋势;在降水天数变化中,徐州地区年降水天数均减少,但年极端降水天数除徐州站外,其余两站点均呈增加趋势。(3)徐州城市化发展对区域降水变化没有显著影响,徐州地区的降水主要受大气环流影响,城市化发展只是增加了降水序列短时段的波动变化。The precipitation observation data from 3 meteorological stations in Xuzhou from 1967 to 2016,XuZhou,Suining and Pizhou stations were used to discuss the characteristics of precipitation changes in Xuzhou and the impact of urban development on it in this paper.The results are,(1)the urbanization of Xuzhou developed faster,the development effect was better.The regional economic growth was stabled,the industrial structure was actively transformed,and the layout was reasonable.(2)In the change of annual precipitation in Xuzhou,there was a small increase in annual precipitation in Xuzhou,and Suining stations while the Pizhou station was decreased.In the change of annual precipitation days,the number of precipitation days in Xuzhou was reduced,and the number of annual extreme precipitation days the other two stations were increased.(3)The urbanization development has no significant influence on the precipitation in Xuzhou.The precipitation was still mainly influenced by the atmospheric circulation,and the urbanization process only increases the fluctuation of the precipitation sequence in a short period.
