查询词典 runoff

Separately speeking, for outward rivers in Cansu (either to the Yellow River or to the Yangtze River), the allocable water resources are mainly the river runoff and groundwater, the priority sequence of water resources allocation would be: the water use for maintenance of local plantation including the environment-oriented and irrigated ones, water use for social and economic activities, and the runoff to lower reaches.

The root biomass improved the soil infiltration rate and reduced runoff,the runoff and erosion amount of meadow brome decreased by 98.2%and 99.9% respectively,and the ability of water retention and soil-reinforcement of meadow brome was 5.2 and 1.5 times than that of corn.

The effect of Zea mays and Bromus riparius on soil and water loss were studied,the experiment was conducted to plant crop and grass in runoff-plots on the 15 degree slope naturally,the bare slop is CK,then the runoff and soil erosion amount and the biological characteristics of corn and meadow bromes termly were measured,and difference of soil and water loss prevention effect on the slop land were determined.The results showed that soil and water loss became less after both corn and meadow brome planting.And the leaf area and the coverage of meadow brome higher than corn,which was benefit for less soil and water loss at the rain season early.Meanwhile,roots of corn and meadow brome mainly distributed in 0-10 cm soil layer,and the root biomass of meadow brome was 2.88 times than that of corn.

试验在自然降雨条件下，在15°坡地设置作物与牧草径流试验小区，以裸地为对照，在每次降雨之后用全深剖面采样器取样，测量其径流量和土壤侵蚀量，定期测定玉米和草地雀麦的生物学特性，研究玉米与草地雀麦生物学特性变化及其坡地水土流失防治效果的差异，探索植物种植对坡地水土流失的主要影响因素，结果表明：种植玉米与草地雀麦，对坡地水土流失均有一定防治作用，但是，与玉米相比，草地雀麦的叶面积指数和覆盖度可在雨季前达到较高水平，有利于早期坡地水土流失防治。

In the Yellow River and Dadu River a trend of increase in runoff has appeared, but in most rivers the runoff has still fluctuated below normal since the e...

据黄河流域径流对气候变化的敏感性分析，如果气温升高2℃，即便降水量增加20％，该流域的夏季径流量也将减少3％左右。

The results showed that covering the dich slopes with shrub could significantly increase soil shear strength, compactness and moisture content, and the formed vegetation had significant effects on retarding runoff and removing TSS (P.05). Applying live fascines could significantly increase soil shear strength and TSS removal rate (P.05), but its effects on increasing soil compactness and moisture content and retaining runoff were not significant.

结果表明：与对照相比，使用灌丛垫技术修复后的坡岸土壤剪切力、紧实度和土壤湿度显著提高(P.05)，坡岸植被延缓径流和去除悬浮物效果显著(P.05)；使用柴笼技术修复后的坡岸土壤剪切力和悬浮物去除率显著提高(P.05)，但对土壤湿度、紧实度和雨水径流的延滞作用不太明显。

It collects the data of sediment discharge and runoff depth of key hydrometric stations of the Yellow River and its main tributaries in the last 50 years and studies the normal variation of absolute value of sediment discharge and relative runoff depth by using mathematical statistics.

收集了黄河重要干流水文站和一些主要支流近50年的输沙量及径流量数据，应用数理统计方法研究了输沙量绝对值和相对径流量的多年变化情况。

And according to the characteristics ofunderlaying surface of catchments and that of runoff, the variation of impoundage was takeninto consideration in runoff model.

并通过分析流域下垫面和径流特点，考虑了土壤蓄水容量的变化，进一步认识流域水文循环变化规律，提高了洪水预报精度。

The research quantified the effects of geographical environment factors about runoff and sediment generation to provide rationable foundation to differentiate cell of runoff and sediment generation and to the construction of ecological environment in a watershed.

定量评价影响渭河流域产水、产沙的地理环境要素因子，为渭河流域产水、产沙格局划分及流域生态环境建设提供理论依据。

During the establishment of sediment yield dynamic model at the watershed outlet, it was difficult for us to carry out dynamic monitoring of each impact factors in the whole basin, because it was a long time research and was in very large-scale watershed. Taking into account the interannual variability of sediment yield mainly affected by hydrological conditions of rainfall - runoff and underlaying surface changes caused by soil conservation measures, a combined influence factor which is related to surface runoff modulus and the implementation time of the water and soil conservation project was proposed for the first time. Furthermore, its specific expression was determined through dimensional analysis and non-linear regression multianalysis.

在流域输沙量动态模型的建立中，由于研究时段长、研究流域尺度大，对输沙量各影响因子进行全流域逐年动态监测十分困难，考虑输沙量的年际变化主要受降雨-径流水文条件和水土保持措施等土地管理活动的影响，首次提出与地表径流模数和治理时间相关的综合影响因子，并通过因次分析法和二元非线型回归法确定了具体的表达式。

Wavy distribution of soil water along hillslope resulted from the fluctuation of runoff, upslope runoff infiltration, lateral downslope flow, and the difference of infiltration rate and evapotranspiration.
