There are thinks the double features of saline and alkaline for the formation and evolutionprocess of the salinization soils in this region,the generation intensity and scale are related withgeomorphological types,shallow water geochemical types,shallow water table and soil structureetc.,presents the quantity relationship between the salinization degree of the soils,shallow watertable and mineralization,expounds the four stage and seasonal succession features of slattransference and inversion,discuss the interaction between ions in shallow water and soils and thethe regularity of the salt transference and accumulation under freeze-thaw action.

本文在野外调查、监测及实验研究的基础上提出松嫩平原盐渍土的形成过程存在盐化与碱化双重作用，其发生强度和规模与地貌、潜水类型、径流条件、潜水水位、土壤结构有关，提取出潜水埋深、矿化度与土壤盐渍化程度关系的定量指标，以及土壤盐分迁移转化季节性变化的四个阶段及其特征。同时重点研究了潜水与土壤之间元素交互作用及冻融作用下盐分迁移和聚积规律，为土壤次生盐渍化的防治提供了理伦依据和技术支撑。
