近50年赣西北大坑小流域径流对降雨的响应
- Title:
- Response of Runoff to Rainfall in Dakeng Small Watershed in Northwestern Jiangxi Province over the Last 50 Years
- 分类号:
- P468.0+24
- 摘要:
- 根据赣西北大坑小流域1957—2005年逐日降雨和径流资料，采用时间序列分析法和统计回归分析法，对降雨变化及径流的响应进行了分析。结果表明：（1）大坑小流域1957—2005年平均年降雨量为1 596.3 mm，其年内变化为典型的单峰型曲线，降雨的季节差异非常明显，同时，降雨量的年际变化较大，总体呈增加趋势。（2）大坑小流域1957—2005 年平均年径流深为814.3 mm，其年内变化为单峰型曲线，径流深的季节差异较大，同时，径流深的年际变化较大，总体呈增加趋势。（3）从年径流深与年降雨量的回归分析可知，大坑小流域的降雨量与径流深之间存在密切的相关性。当水文年降雨量增加或减少10%时，年径流深会表现出增加或减少17.8%的正响应；当水文年降雨量增加20%或减少30%时，年径流深会表现出增加35.6%或减少53.4%的正响应。
- Abstract:
- Based on the data from 1957—2005 in Dakeng Small Watershed in Northwestern Jiangxi Province, the analysis of precipitation variation and its runoff response were carried out by mean of time-serial eigenvalue, statistical regression. The results suggested that: (1) annual mean precipitation is 1 596.3 mm, which monthly variation has presented a single-peak pattern during a year, and the difference of quarterly precipitation is very obvious. What’s more, the annual variation of precipitation is bigger and presents increasing tendency totally; (2) annual mean runoff depth is 814.3 mm, which monthly variation has presented a single-peak pattern during a year, and the difference of quarterly runoff depth is very obvious. What’s more, the anuual variation of runoff depth is bigger and presents increasing tendency totally; (3) runoff depth changes are closely correlated with precipitation variations. While annual hydrological precipitation increased or decreased by 10%, annual runoff depth shows 17.8% of positive response. Meanwhile, while anuual hydrological precipitation increased or decreased by 20%(30%), the corresponding anuual runoff depth shows 35.6%(53.4%)of positive response.
