输沙量

年输沙量总体减少，河水含沙量增大，泥沙淤积严重；

Sediment load per year decreased generally , sediment concentration of water increased , and the sand silting up was serious ;

相似降水条件下，90年代延安站洪水的洪峰流量、洪量和输沙量比80年代有所减少；洪水历时延长，洪水过程线呈现涨洪陡、落洪缓的特点。

Under the similar precipitation , flood peak flow , flood volume and sediment load at the Yanan station are all smaller in the 1990s than in 1980s .

受水体生产力和长江输沙量的季节变化影响，颗粒态P和N含量在春季高于秋季，但有机组分的比例春季低于秋季。

Impacted by the seasonal variations of primary productivity and Changjiang sediment load , the concentrations of particulate P and N were higher in spring than those in autumn , while the percentage of organic component were lower in spring .

实验测得0～20cm高度范围内风沙流输沙量较流沙地减少了80.2%，小气候及土壤等生态条件明显改善；

According to experiment , within the height of 0-20 cm , sand transport is reduced by 75.8 % , and environment , soil and other ecological conditions are obviously improved .

陕北黄土丘陵沟壑区总面积447万km2，水土流失极为严重，年输沙量达66亿t。

The gullied rolling loess region in northern Shaanxi is the region of severe soil and water loss with area of 44 700 km 2 and annual sediment production of 660 million tons .

根据利津水文站实测资料，黄河多年平均径流量和输沙量分别为309.88×108m3、6.23×108t，且呈显著减少趋势。

The annual average runoff and sediment of the Yellow River is 309.88 × 108m3,6.23 × 108t according to the measured data of Lijin station , respectively , and decrease significantly .

全省水土流失面积1375万km2，年平均输沙量92亿t，占全国水土流失总量的1/5，截至2000年底，全省已治理水土流失面积85万km2。

There is soil and water erosion area of 137 500 km 2 in Shaanxi province with annual average sediment transportation of 920 million tons that account for one fifth of total soil and water loss in China .

在NW风作用下，网后10m、2m的输沙量分别是网前10m、2m的1/29和1/43，并受栅栏设置等因素的影响。

The sand transport of 10 m and 2 m behind the net fence are 1 / 29 and 1 / 43 , respectively , under the control of NW wind , and these ratio are also influenced by many other factors , such as the net fence layout .

结果表明：皖水流域内输沙量与日雨量为50～100mm的暴雨和地表径流量的关系最为密切。本文通过对输沙量与降雨径流因子研究。

The results indicate that an amount of sediment transport has a very close relation with rainstorm of 50 ~ 100 mm of daily rainfall and runoff . This paper deals with the relationship between an amount of sediment transport and runoff factor .
