盐碱地改良措施概述

An Overview of Saline-alkali Land Improvement Measures

盐碱土是盐土和碱土以及各种盐化和碱化土的总称,盐碱土的形成实质主要是各种可溶性盐类在地面作水平方向与垂直方向的重新分配,从而使盐分在土壤表层逐渐积聚起来。气候作用、耕作技术不合理、地下水位抬高等因素,均能导致土壤盐碱化,严重的盐碱化地区植物几乎不能生存。开发利用盐碱地不仅可以扩大耕地面积,改善生态环境,改善人类生活,随着利用技术的提高,甚至可以从盐碱地获取化工原料、燃料等。因此研究盐碱土的治理改善,具有重要的意义和价值。盐碱地治理是世界普遍存在的挑战,本文从技术措施和管理措施两个方面分别介绍了盐碱地治理的相关技术和管理措施,为盐碱地治理利用提供理论支撑。

Salinized soil is the general name of salinized soil and alkaline soil as well as various salinized and alkaline soil.The formation of salinized soil is mainly the redistribution of various soluble salts in the horizontal and vertical directions on the ground,so that the salt gradually accumulates on the surface of the soil.Factors such as climate,unreasonable tillage techniques,and elevated water table can lead to soil salinization,and plants in severely salinized areas can hardly survive.The development and utilization of saline-alkali land can not only expand the cultivated area,improve the ecological environment,and improve human life.With the improvement of utilization technology,chemical raw materials and fuels can even be obtained from saline-alkali land.Therefore,it is of great significance and value to study the improvement of saline-alkali soil management.Saline-alkali land management is a universal challenge in the world.this paper introduces the relevant technology and management measures of saline-alkali land management from two aspects of technical measures and management measures respectively,providing theoretical support for saline-alkali land management and utilization.
