This is changeable and rapid rate of sediment production . 這是種多變而快速的沉積作用。
Management of the area with coarse and main sediment production and the yellow river soil and water conservation ecological project construction from 2001 to 2005年多沙粗沙區(qū)治理與黃河水土保持生態(tài)工程建設(shè)
The analysis shows that the average annual runoff volume has a little increase due to human activities after management , but the average annual sediment production has greatly decreased 通過分析發(fā)現(xiàn),治理后流域內(nèi)的人類活動使年均徑流量比治理以前略有增加,而年均輸沙量卻比治理以前大幅度減少。
Coupling vegetation dynamics at multiple scales is essential to explore the mechanisms of water and sediment yield response to vegetation changes such as vegetation reestablishment , development , succession , distribution , and management practices - we reviewed literature on advances in studying the processes and mechanisms of the vegetation influence on runoff and sediment production in relations to vegetation growth , vegetation succession , vegetation patterns and distribution , as well as afforestation and deforestation 由于植被自身的生長發(fā)育以及受自然因素和人為干擾的作用,植被變化具有多尺度性;由于受流域水文環(huán)境的異質(zhì)性和水文通量的變化性的影響,流域水文過程也同樣具有多尺度性。
The outcomes show that cultivation measures have the reduction functions of run - off energy and slope sediment production , of which , the action of contour cropping is the maximum and the action is reduced along with the increase of rainfall intensity and surface gradient ; cultivation measures also have a certain correlation on the reduction functions of run - off energy and erosion , in the meanwhile of slope sediment production , it is effected by the factors of soil erosion resistance and scouring resistance 結(jié)果表明:耕作措施對徑流能量及坡面產(chǎn)沙均具有削減作用,其中等高耕作的作用最大,隨雨強和地面坡度的增大其作用減弱;耕作措施對徑流能量的削減作用與減蝕作用之間具有一定的相關(guān)關(guān)系,但坡面產(chǎn)沙同時受土壤抗蝕、抗沖性等因素的影響。
