drainage basin yield

基本解釋

The DYRM was run to simulate the process of water and sediment yield on slopes in the Middle Yellow River basin, considering the drainage division of water and sediment source areas.
在黃河流域產(chǎn)水產(chǎn)沙子系統(tǒng)修正分區(qū)的基礎(chǔ)上，用黃河數(shù)字流域模型模擬計算中游流域的產(chǎn)水、產(chǎn)沙過程。
Research on drainage basin erosion and sediment yield amount is not only an important task in physiognomy, but also an important one in river harnessing and water conservancy construction.
流域綜合治理規(guī)劃、防治土壤侵蝕、合理利用水沙資源，無不需要掌握流域產(chǎn)沙情況。
Drainage area(A)is a lumped variable as all the environmental variables are involved within it, and specific sediment yield(Ys)is an index of soil erosion intensity of some drainage basin.
流域產(chǎn)沙模型是研究土壤侵蝕和水土流失的主要方法，是解決流域生態(tài)和環(huán)境問題的有效途徑。
