“salinization”的概念、定义、翻译、参考文献-科学参考

salinization

Biology

An increase in the salt content of the soil (or of a body of fresh water), which can lead to the retardation of plant growth and eventually renders the soil infertile. This problem is particularly acute in hot areas, where water readily evaporates from the soil, and it may also occur as a consequence of irrigation. Salts dissolved in irrigation water build up in the soil as the water evaporates, making the water potential of the soil water more negative. This reduces the gradient of water potential between the soil water and the roots, reducing the rate of water uptake by the roots.

Geology and Earth Sciences

The process of accumulating soluble salts in soil, usually by an upward capillary movement from a saline groundwater source, followed by evaporation from the surface.

Geography

The accumulation of unusually high concentrations of dissolved sulphates and chlorides of sodium and calcium, often as a result of large-scale irrigation in semi-arid areas; as irrigation water is evaporated or transpired, the salt ions are largely left behind to accumulate in the soil (Saysel and Barlas (2001) Ecol. Model. 139, 2–3). Salinization can reduce plant growth rate and yield, and, in severe cases, cause total crop failure. In certain circumstances, excessive salinity in soils cannot be reduced over time by routine irrigation and crop management practices (Qadir et al. (2000) Land Degrad. & Dev. 11).
In coastal areas, salinization can be associated with the over-extraction of groundwater, which can lower the water table and lead to the invasion of sea water (Cardonna et al. (2004) Env. Geol. 45, 3). Tsunamis can cause severe salinization problems.
