吉林省西部地区土壤盐渍化及防治简析

摘要

Salinization of soil chemistry and engineering properties research on comprehensive utilization of land and wa -ter conservancy engineering construction project is very important .The salinization is formed mainly by groundwater and meteorological factors ,lake shrinking ,micro topography and the effects of hydraulic engineering construction and manage-ment.Salinization of soil salt content is high ph value ,high compressibility and low shear strength .Soil improvement by engineering and biological measures and saline soil for earthwork compaction improvement measures remains to be stud -ied.%盐渍化土的化学及工程特性研究对盐渍化土地综合利用及水利工程建设项目至关重要；盐渍化的形成主要受地下水及气象因素、湖泡萎缩、微地貌及水利工程建设与管理影响；盐渍化土含盐量高、 pH值高、高压缩性、低抗剪强度；土壤改良可通过工程及生物措施；盐渍土用于土方填筑改良措施仍有待研究。
