2.Salt-affected soils的形成: 受鹽害土壤發生的原因: 1.氣候因素: 在乾旱和半乾旱地區,由於年雨量低於蒸發散量,似致鹽分無被淋溶出土壤,而累積成有害植物生長的量。 2.地形因素: 在低窪地區的土壤,可能會有較高的地下位,當地表發生蒸發作用時,地下水可能會藉由毛細作用往上移動至土壤表面,這種水份由下往上...

Salt-affected soils are those soils which have high levels of soluble salts and/or sodium in excess of the limits which can be tolerated by crops. Soils with excess soluable salts are referred to as SALINE SOILS. Those soils with excess sodium are referred to as ALKALI (...
Salt-affected soils, those on which plant growth is limited by an excess of salts, are of three types: (i) saline soils in which electrical conductivity is > 4 dSm1; (ii) sodic soils in which the exchangeable sodium percentage (ESP) is > 15; and (iii) saline-sodic in which the ...
In salt affected soils that are also sodic, i.e., soils in which the sodium adsorption ratio (SAR) is greater than 5, the soil is considered a sodic soil and the conditions may adversely affect soil structure and stability, and subsequently the growth of most crop plants. ...
