Osmotic potential could be estimated by the difference between the potential of natural salt-affectedsoil and that of the salt-leached soil.
盐分非常显著地降低了土壤的水势,可以用盐化土样的水势与脱盐处理土样的水势估算盐化土样的渗透势。

Main environmental geological problems are salt-affectedsoil in north of Yinchuan Plainand desertification in north-middle of Ningxia and montanic soil erosion in south of Ningxia.
Based on the character and practical status of salt-affectedsoil, it is economical, reliable, simple and fesible to adopt changing soil method and to deepen foundation mat to treat the foundation.
