盐碱化是全球性的土壤退化问题。盐碱化草地恢复技术包括物理改良技术、化学改良技术、水利改良技术和生物改良技术,但这些方法都有一定的限制因素。物理改良技术的成本较高,大面积治理时存在困难,往往只是临时性措施。化学改良技术见效快,但可能造成二次污染。水利改良技术在内陆缺水地区难以使用。需要根据当地实际情况将不同的改良方法结合使用。
Salinization is a global problem of soil degradation. Salinized grassland restoration techniques include physical improvement techniques, chemical modification techniques, water improvement techniques and bioremediation techniques, but these methods all have certain limitations. The cost of physical improvement technology is high, and there are difficulties in large-scale governance, which are often only temporary measures. Chemically improved technology works fast, but may cause secondary pollution. Water improvement technologies are difficult to use in inland water-scarce areas. Need to be based on the local situation will be different ways to improve the combination.
