松嫩平原盐渍土积盐与碱化关系及发展趋势研究

DEVELOPMENT TREND AND RELATIONSHIP BETWEEN SALINIZATION AND ALKALIZATION OF SALT—AFFECTED SOIL IN SHONG LIAO PLAIN

摘要:

本文尝试运用相关和通径分析等数学方法,对松嫩平原低地形成的各类苏打盐渍土按其积盐程度,即发育阶段进行了分析研究。初步探视了本区盐碱土形成的特点,明确了盐碱土形成中盐化与碱化的相互依赖关系及形成碱化土的主要影响因素,并由此推断松嫩平原苏打盐渍土是盐化、碱化同时发展,而不同于内蒙古高原的脱盐碱化过程。松嫩平原的苏打盐渍土目前还处于继续发展阶段。

Abstract:

The relationship between salinity and development of salt—affected soil formed in Shong Liao plain was studied with the method of analysis of correilation and path coefficient. This paper laid bare the formation, characteristic of saline—alkali soil and defined the dependence relationship between salinization and alkalization. The major fatter which affect the alkalization of scils has been found. The authors believe that salinizati on and alkalization of saline—alkali soil in Shong Liao plain is in progress and develops at same time.
