| 摘 要： | 根据浙江省63个站点逐日降水量,采用"降水集中期"的雨涝指标对浙江省1971-2006年的降水资料统计分析.进行雨涝等级评估.分析了浙江省近36 a雨涝灾害的时空分布.结果表明:雨涝等级在时间尺度上,有逐步加强的趋势;在空间分布上,中北部地区弱而东南、西南及南部强.且"降水集中期"相对于其他的雨涝指标.在实际应用中更为客观有效. |
| 关 键 词： | 降水集中期 雨涝 时空分布 |

| Abstract: | The daily precipitation data of 63 meteorological stations in Zhejiang province are used to calculate the waterlogging indices with the concept called precipitation concentration period(PCP).The spatial and temporal distribution of the indices shows that the waterlogging ranks,which are weaker in the middle and northern parts and stronger in the southeastern and southeastern parts of the province,increase as time goes on.Futhermore,compared with other endices,PCP is more objective and effective in applicati... |
