土壤盐渍化 - 百度百科
土壤盐渍化（soil salinization）是指土壤底层或地下水的盐分随毛管水上升到地表，水分蒸发后，使盐分积累在表层土壤中的过程。 是指易溶性盐分在土壤表层积累的现象或过程，也称盐碱化。
Soil salinity - Wikipedia
Soil salinity is the salt content in the soil; the process of increasing the salt content is known as salinization. [1] Salts occur naturally within soils and water. Salination can be caused by natural processes such as mineral weathering or by the gradual withdrawal of an ocean.

土壤鹽化 （英語： soil salinization，又稱 土壤鹽鹼化）是常發生於氣候炎熱、乾燥，實施 灌溉 卻排水不良之 沙漠 及沿海地區等農牧業地區的現象。 鹽害會危害建築物、公共設施以及出土遺蹟。 中國北方和印度的 旁遮普地区 也為此問題所苦。 沙漠空氣中的水分少但水分蒸發量卻很大，當蒸發量大於 降雨 量和 地下水 下滲量時， 土壤 中含鹽分和鹼的地下水受蒸發作用（毛細管作用）而被引到地上。 然而，當水被蒸發後，水中的 鹽 分仍留在陸地表面或建築物內結晶，最終可能 …
Soil Salinization: How To Prevent And Manage Its Effects
2021年2月21日 · Salinization reduces biodiversity in rivers or fresh-water lakes, shortening aquatic populations solely to salt-tolerant species. Soil salinization effects refer to crop diversity and, correspondingly, food variety as farmers are forced to …
Soil Salinization - an overview | ScienceDirect Topics
Soil salinization is a term that indicates the phenomenon or process of accumulation of water-soluble salt in the soil. Based on the drivers and mechanisms, it can be summarized in two subcategories: primary salinization, and secondary salinization (Li et al., 2014).
Salinization - an overview | ScienceDirect Topics
Salinization is the precipitation of salts in soils (Fig. 3) and is found mostly in desert soils (Aridisols). The most common salts are halite and gypsum, which can form either as clear crystals within soil cracks or as sand crystals that engulf the pre-existing soil matrix.

2021年11月18日 · Excess salt accumulation in the root zone causes soil salinization influencing soil health, biodiversity and food security.
Why is salinity and salinization important? Salinity and salinization can impact working lands in many ways. levated salinity levels can cause crop yield declines, coastal forest loss, salt-tolerant invasive species takeover, and eutrophication and marsh migration. ew
Soil salinity and salinization | SpringerLink
2016年1月1日 · Salinization occurs when water, carrying dissolved salts, evaporates at the soil surface, frequently leaving a white salt crust at the soil surface. Salinization is generally more pronounced in arid and semi‐arid, than in more humid regions, because of insufficient rainfall to flush accumulated salts from the crop root zone.
