Jinsha river is a main sediment source in the upper reaches of the Yangzi river.Through statistical analysis to water and sediment data of major hydrological control station in Jinsha river basin,the sediment transport characteristics of the basin which include sediment sources and distribution, annual variation and annual distribution of sediment discharge,the relationship between runoff and sediment discharge,and the genesis of sediment are discussed. It provides a scientific basis for the rule of soil...

Jinsha river is a main sediment source in the upper reaches of the Yangzi river.Through statistical analysis to water and sediment data of major hydrological control station in Jinsha river basin,the sediment transport characteristics of the basin which include sediment sources and distribution, annual variation and annual distribution of sediment discharge,the relationship between runoff and sediment discharge,and the genesis of sediment are discussed. It provides a scientific basis for the rule of soil eorsion and sediment transportation researching,and soil and water resources reasonable developing and utilizing in Jinsha river basin.

金沙江是长江上游河流泥沙的主要来源。通过对金沙江流域主要控制水文站径流泥沙资料的统计分析,论述了金沙江河流泥沙的来源和沿程分配、输沙量的年内分配和年际变化、径流量和输沙量的关系,以及泥沙形成的原因。为研究金沙江流域的水土流失和泥沙输移规律,合理地开发和利用其水土资源提供了科学依据。

Owing to there is many branch of the river and a few of hydrological control stations, the dominant discharge cannot be computed and the dredging discharge cannot be fixed on in regulating and dredging flood passage of Dongting Lake. Whereas the sediment of 80% in the lake comes from the flood of Yangtze river, the discharge transmitting to the regulated river reach from Yangtze river representative year flood possessed obvious dominant action is regarded as the dredging discharge. The analysis of Liishui...

Owing to there is many branch of the river and a few of hydrological control stations, the dominant discharge cannot be computed and the dredging discharge cannot be fixed on in regulating and dredging flood passage of Dongting Lake. Whereas the sediment of 80% in the lake comes from the flood of Yangtze river, the discharge transmitting to the regulated river reach from Yangtze river representative year flood possessed obvious dominant action is regarded as the dredging discharge. The analysis of Liishui flood passage shows the method is feasible. [

洞庭湖洪道分汊很多,水文控制站少,整治疏挖无水文控制站的洪道,无法计算造床流量,也无法确定疏挖流量。鉴于洞庭湖区泥沙 80%来自长江洪水,选择造床作用较强的长江典型年洪水传播至整治河段的流量,作为该河段的疏挖流量,通过对澧水洪道的分析,该方法是可行的。

Based on the observed streamflow of 19 key hydrological control stations in the six larger basins in China for the past 50 years,this study employed the Mann-Kendall test to detect trends of annual runoff.It was found that annual runoff in the six larger basins has generally decreased during the periods,with signicant decreases detected in the northern China.Especially in Haihe river,Yellow river,Liaohe river and Songhuajiang river,there are remarkable decreasing trends.

应用1950年以来的中国六大流域19个重点控制水文站年径流观测资料,采用MK检验方法研究了中国六大江河的年径流量变化情况。结果表明,近50年来中国六大江河的实测径流量均呈下降趋势。其中海河、黄河、辽河、松花江实测径流量下降明显,严重影响了我国社会经济的发展。
