runoff cycle

基本解释

Rainfall is a key factor affecting soil erosion and nutrient cycle by runoff in low hilly red soil area.
降雨是影响低丘红壤坡地土壤侵蚀和养分随径流迁移的一个关键因子。
The regime of unsaturated soil moisture is an important part of the runoff cycle in the Experimental basin.
非饱和带土壤水分状况在实验流域研究中占相当重要部分。
A series of rainfall were selected as the main factor of the basin runoff. Then, the effect of rainfall on runoff and hydrological cycle was revealed through the distributed hydrological model.
选取降雨作为流域径流的主要影响因子，随机设定一系列降雨情景，通过模型计算有效揭示降雨对流域径流及水文循环的影响效应。
