| 摘 要： | 根据1965～2016年嘉陵江北碚水文站实测径流泥沙资料,研究了嘉陵江水沙通量演变规律。结果表明,嘉陵江年径流量有减少趋势,但不显著,而年输沙量下降趋势显著,且通过95%置信度检验;嘉陵江径流量和输沙量分别存在32、28年的周期性变化规律;水库拦沙等人类活动为嘉陵江年输沙量显著减少的主要原因。

Driving Factors Analysis of Evolution of Runoff and Sediment at Jialing River in Resent 50 Years |
| |
| Abstract: | Based on the observation data of annual runoff and sediment during 1965~2016 at the Beibei Station in the Jialingjiang River, the evolution characteristics and laws of annual runoff and sediment were revealed. The results show that the amount of annual runoff appears a slightly decreasing trend, but the trend is not significant; The amount of annual sediment shows an obviously decreasing trend and passes 95% confidence level inspection; There are periodicities of 32 years and 28 years for annual runoff and sediment processes, respectively; Human activities like reservoir sediment blocking are the main reasons for the significant decrease of annual sediment transport in the Jialingjiang River. |
