摘要
该文提出了水土流失系统物质和能量容量的概念,分析了它与水土流失的关系,结果表明水土流失系统物质与能量的过剩是引起水土流失的主要原因。同时还讨论了降雨的潜在势能、径流势能以及坡面系统物质所具有的势能的计算公式,提出了水土流失系统物质和能量交换的可能途径。
The conception of substance and energy capacities are put forward, the relations between soil and water loss and substance or energy are analyzed. The results show the main cause of soil and water loss are due to surplus of systematic substance and energy. The same time, the calculating formulae for potential of rainfall, runoff and systematic substance on slope face are discussed. The exchange approch of substance and energy in the soil and water loss systems are given.
