影响水土流失主要因子间相互关系研究
- Title:
- Study on the Relation among Factors Affecting of Soil and Water Loss
- Keywords:
- soil and water loss; factors; relation; precipitation; slope length; slope grade; runoff potential energy; substabce and energy; capacity
- 摘要:
- 利用物质和能量之间的分析式研究了影响水土流失主要因子之间的相互关系，结果表明：降水量和系统容量之间是一种线性关系；降水总量和坡长、坡面宽度仍是一种线性关系且降水增量与坡长坡面宽度的增量是同步的，降水总量和坡度的关系是一种余弦关系；降水量和能量之间的关系是线性关系；水土流失系统容量和径流势能之间是一种线性关系。
- Abstract:
- The relation among the factors affecting of soil and water loss have been studied using mathmetical function of substance and energy. The results shows: the relation between precipitation and systemical capacity is linar and also linar relation between the whole amount of preipitation and slope width, the increase of rainfall is as syschronism as the increase of slope length and slope width, there is COS- function, existed between precipitation and slope grade. Linar is the relation between precipitation and energy, and also the relation between systemical capacity of soil and water loss and runoff potential energy.
