摘要

为探索水土流失的影响因素

防治水土流失

采用自制水土冲刷试验装置

通过平行对比模拟试验

研究了无机盐和无机酸碱溶液对土壤侵蚀的影响规律。结果表明

无机盐溶液对土壤侵蚀作用大小与盐溶液的种类、浓度有关

在溶液中的阴离子相同的条件下

溶液的阳离子不同

冲刷的产沙量不一样

盐溶液浓度变化对土壤侵蚀的影响规律可分为四种:上升型、下降型、波峰型和波谷型。无机酸碱溶液对土壤侵蚀作用大小与酸、碱种类有关

H2SO4

HNO3的产沙量大

H3PO4

HCl的产沙量小;NaOH

KOH的产沙量大

Ca(OH)2

NH3.H2O的产沙量小;碱溶液对土壤的冲刷产沙量远大于酸溶液的产沙量

酸、碱溶液的产沙量均比清水大。
