摘要
基于不同年份土壤盐渍化调查情况,分析了宁夏扬黄灌区盐渍化的演变规律与发展趋势。气候因素、高含盐土壤母质、障碍土层、局部地势低洼、常年有灌无排等是宁夏扬黄灌区土壤盐渍化产生的主要原因。结合扬黄灌区土壤盐渍化特点,集成土壤盐渍化治理技术成果,提出了土壤盐渍化治理的共性措施和不同成因的针对性措施,旨在为灌区土壤盐渍化的治理提供借鉴。
Based on the investigation results of soil salinization in different years, this paper analyzed the evolution laws and development trends of soil salinization in irrigation areas of Yellow River in Ningxia. The main reasons include the climatic factors, parent materials, with high salt content, barrier layer, local low-lying areas, and only irrigating without drainage throughout the year. According to the characteristics of soil salinization and technological achievements of soil salinization control, this paper put forward the common measures and targeted measures for soil salinization control, aiming to provide references for soil salinization control in irrigated areas.
