泰和县降雨及侵蚀性降雨变化趋势分析
摘要:基于泰和县(北纬26°27''-26°59'',东经114°57''-115°20'')1981年~2010年的降水数据,统计出泰和县降雨以及侵蚀性降雨的年平均雨量、月雨量、累计各月最大日雨量、暴雨和大暴雨等降雨事件频率等。并通过系统分析,探究降雨的时间特征和降雨年度的规律性,研究分析表明:, ,30年来降雨量、侵蚀性降雨量呈现不显著的减少趋势,但年际变化逐渐增大。夏、秋两季降雨量呈不显著的增、减趋势, 春、冬两季则不显著的减、增趋势。每7年至8年就会有一年的暴雨事件就会频繁发生,且暴雨事件主要集中在每年的6月份。

Analysis of Taihe County rainfall and erosive rainfall trend
Abstract: Based on the Taihe County (26 ° 27 '59-26 ° north latitude', longitude 114 ° 57 '115 ° 20') precipitation data from 1981 to 2010, The statistics of Taihe County rainfall and erosive rainfall average annual rainfall, rainfall, accumulated the maximum daily rainfall, rainfall and rainfall frequency. And through the analysis of the system, regular time characteristic and the rainfall annual rainfall of the study, research and analysis shows that: during the past 30 years, the average rainfall of Taihe County is , erosive rainfall is . The interannual variation of gradually increasing. In 30 years, Rainfall Erosive Rainfall showed no significant decreasing trend. Summer, autumn two season rainfall was not significantly increased, decreased, spring, winter two season is not significantly reduced, increas
