摘要
盐碱地治理的根本措施是控制水盐运移方向,降低地下水位,通过工程措施合理的控制地表水水位,使水位降低到耕作层深度以下。在"改排为蓄、水地共处、和谐生态"综合治理模式思想的指导下,通过"土体有机重构"工程,科学掌握水盐运移规律,改良盐碱地,使盐碱地适合农作物生长,逐渐达到高产、稳产。本文以陕西省定边县堆子梁镇盐碱地土地开发整理项目为例,从土地开发工程的角度对盐碱地治理措施进行论述。
The essential measure of saline-alkali land management is control the flowing direction of the saline water,lowering the underground water level,and reducing the surface water level under the plough layer by projects to achieve the high yield gradually under the guidance of the mode of integrated management which is changing drainage to storage,water-land coexistence,harmonious ecology.Through utilizing the project of land organic reconstruction,and master the law of water and salt transport scientifically,the saline-alkali land would be improved and suitable for agriculture.This paper takes the land development and consolidation project of saline-alkali land in Duiziliang of Dingbian county of Shaanxi province as an example to discuss the management of control the saline-alkali land from the perspective of the land development projects.
