| 摘 要： | 受全球气温上升影响,广州市区水文要素出现了明显的变化.为揭示广州市降雨时空变化趋势,采用Mann-Kendall检验法从不同方面分析了降雨时间序列的演变规律,可知市区年降雨量逐年增加,暴雨中心由市郊向市中心转移,降雨时段更为集中.并采用不均匀系数结合Mann-Kendall检验法分析了降雨的时空分布及其变化趋势,发现广州市降雨量年内分配不平衡,且降雨空间分布不均匀.

| Abstract: | The hydrological factors in Guangzhou City are obviously changed by the effect of global air temperature rising in recent years.In order to reveal the variation trend of rainfall factors in Guangzhou City,the Mann-Kendall test method is used to analyze the variation trend of rainfall time series.The results show that annual rainfall in urban region is gradual increased,and the storm center is transformed from the suburban region into in the urban center and rainfall duration is more concentrated.The tempora... |
