本文首先闸述了是壤盐渍化预测预报研究对于土壤盐渍化防治的重要意义及土壤次生盐渍化形成的主要原因及其预报。概述了土壤盐渍化预测预报研究的方法:1.地理相似法,2.专家预测法,3.水盐平衡法,4.数学模型法,5.土壤水盐动态法。对开展我国土壤盐渍化预测预报研究提出了几点看法;1.要加强土壤水盐动态的定量研究,2.建立水盐动态观测场,3.开展典型地区水盐动态的长期观测,4.加强基本参数的研究,5.进行水盐测试方法的研制。
This article begins with a discussion of the importance of soil salinization prediction and prediction for soil salinization prevention and control as well as the main causes of formation and prediction of soil secondary salinization. The methods of soil salinization prediction and forecasting are summarized as follows: 1. Geographic similarity method, 2. Expert prediction method, 3. Water and salt balance method, 4. Mathematical model method, 5. Soil water and salt dynamic method. (1) We should strengthen the quantitative study of soil water and salt dynamics, (2) Establish dynamic observation field of water and salt, (3) Carry out long-term observation of water and salt dynamics in typical areas, 4 To strengthen the study of basic parameters, 5. Development of water and salt testing methods.
