降水与冰川融水径流量增加百分率相比,增加幅度较小。
But, as compared to the increased percentage of runoff from glacier meltwater, the increase amplitude is smaller.
河流的径流量减少正增加非洲地区淡水资源的压力。
Reduced runoff is increasing the pressure on freshwater resources in Africa.
由于长江源区冰川变化幅度小,虽冰川退缩使冰川融水径流量有所增加,但对径流的影响程度相对较小。
Although retreat of glaciers causes increase in glacier melt water runoff, the effect of glacier retreat on sur - face runoff is relatively small because of small amplitude of glacier change.
对土壤和作物管理的所有处理来说,总径流量随肥料投入量的增加而降低。
For all the soil and crop management treatments, the total runoff decreased with increasing amounts of fertilizer inputs.
自然坡面的非均匀性导致径流集中,由此引起径流流速变化及单宽流量所具有的能量增加。
The uneven natural slope surface has resulted in concentrated runoff, causing the variations of velocity and increased energy of unit width discharge.
秸秆覆盖可有效地降低累积径流量和总侵蚀量,增加累积入渗量;
Straw covering could decreased cumulated runoff and sediment and increased infiltration in the same time.
坡度相同,坡面径流动力学参数及坡面侵蚀量随放水流量的增大而增加。
On the slope of the same gradient, soil erosion and hydrodynamic parameter increased slowly with the flow discharge.
坡面单宽径流能耗随流量增大而增加,随坡度变化呈抛物线趋势,临界坡度出现在21和24之间。
The unit width runoff energy consumption increased with the flow discharge increasing but changed in parabola form. The critical slope is between 21 and 24.
结果表明,坡面径流平均流速随坡度和流量的增加而增大,流速与坡度和流量之间存在指数函数关系,坡度对流速的影响大于流量。
The results show that the average flow velocity increases with the flow discharge and the slope gradient in an exponential form, and the slope gradient has greater effect on velocity than discharge.
