At the same time, soil may have the risk of alkalization.In order to prevent salt-alkalization of soil, the survey network of water and salt should be established. 而豎井灌排影響下的土壤則在整個(gè)剖面上均表現出脫鹽的趨勢，但同時(shí)卻又存在發(fā)生堿化的風(fēng)險及地下水礦化度的提高。
The irrigation area of Tarim, located at the upper reach of Tarim River, is one of the producing area of cotton and markedly affected by soil secondary saline-alkalization. 摘要土壤盆堿化和次生鹽漬化是威脅塔里木灌區農業(yè)生產(chǎn)的主要因素之一。
