When the rain amount is 60.4mm, the sediment modulus of no forest watershed is 31.4 times than covered forest watershed, and the deceasing sediment benefit of forest vegetation reach to 96.81%.      森林植被具有巨大的减沙作用，当降雨量为60.4mm时，无林流域的输沙模数是有林流域的31.4倍，森林植被的减沙效益达到了96.81％。 短句来源      They are positively related to the height and control area of check dam, erosive sediment modulus and the size of sediment particles in the control area of check dam.      拦沙指标变化在 5 0 0～ 760万t/km2 之间 ,与坝高成正比 ,与泥沙颗粒大小成反比 ; 短句来源      It was showed that the distribution of the sediment modulus was greatly uneven and was mainly determined by rainfall and land cover.      可以看出区内输沙模数的区域差异较大,输沙模数的大小主要决定于降雨条件和地表覆盖(包括地表物质组成和植被覆盖)。 短句来源      To a certain extent, the soil erosion intensity could be demonstrated by the sediment modulus.      输沙模数的分布也一定程度上反映了土壤侵蚀强度的区域差异。 短句来源   相似匹配句对      The Study on the Modulus of Erosion and Sediment Deposition of Watershed in Urbanized Development      城市化开发的侵蚀模数及流域淤积量研究 短句来源      modulus decreases.      各模量均有下降趋势。 短句来源      Study on Long-term Average Sediment Transport Modulus of China      中国多年平均输沙模数的研究 短句来源      MODULUS AND CAPACITY      模和容量 短句来源      Melody of History Sediment      历史积淀的旋律 短句来源 查询“sediment modulus”译词为用户自定义的双语例句     我想查看译文中含有：的双语例句 为了更好的帮助您理解掌握查询词或其译词在地道英语中的实际用法，我们为您准备了出自英文原文的大量英语例句，供您参考。          A satisfied method for calculating sediment reduction bencfit in comprehensive control of small watershed is not available at present. The difference of sediment delivery modulus before and after control is usually used to estimate the benefit. This paper pointed out that the sediment delivery modulus had a great variance as it's not reduced by synthetic control but by precipitation, and there was no Significated interrelation between sediment delivery modulus and c...             小流域综合治理的减沙效益,目前还没有比较理想的计算方法,一般都是根据治理前后输沙模数的差异进行推算。本文指出:输沙模数不单纯因为经过综合治理而减小;同时还受降雨情况的影响,因而变化幅度很大。并且输沙模数与降雨量等特征值的相关性不好,故给减沙效益计算带来许多困难。作者经过统计分析发现,输沙模数与径流量之间密切相关。因此可以根据径流量的变化情况,推算出降雨情况对输沙模数的影响,从而可以比较准确地计算减沙效益。 文摘来源          Hechuan county of Chongqing city is the confluent region where the Fujiang River and the Qujiang River join the Jialing River,By calculating,By calculating calculation sediment balance on the sediment data accumulated in many ycars at four stations near the three rivers,it is found that the delivery sediment modulus has been increasing markedly in the interregional rivers. Applying the delivey ratio of the neighbouring areas,the erosion modulus in the interregional river basin ...             根据嘉陵江、涪江和渠江３个水文站的沙量平衡计算表明，该区间河段的输沙模数明显增大。利用邻近地区输移比值，估算了该区段流域的侵蚀模数，参照重庆市采用的土壤侵蚀模数综合值分析，认为川东平行岭谷区的重庆布用中等侵蚀程度评估水土流失程度过于保守。著者根据区间流域产沙量分析，并参照国家标准，认为重庆市用强度侵蚀来评价土壤侵蚀是适宜的。文章还提出了控制泥沙进入三峡水库的６条综合措施。 文摘来源          In the middle reaches of Yellow river basin,a lot of projects have been built.Human activities have changed the land surface and erosion process ,they have also alleviated erosion intensity and retained runoff and sediment. Isograms of sediment transportation modulus and coarse sediment modulus are drawn up based on the obtained data.The variation law of sediment and coarse sediment transportation modulus at areas with more and coarse sediment was an...             该文根据绘制的黄河中游输沙模数与粗泥沙模数等值线图，研究分析了黄河中游多沙粗沙区输沙模数与粗沙模数变化规律。 文摘来源   << 更多相关文摘         相关查询: sediment transportation modulus coarse sediment modulus modulus of sediment sediment yield modulus sediment transport modulus sediment modulus of sediment production modulus of sediment transport modulus of sediment transportation modulus modulus of coarse sediment transportation annual average sediment transport modulus  对查询结果不满意
