摘要:通过野外土壤调查和采样分析,对黄河三角洲土壤盐渍化形成的天然环境和影响因素进行了概述,对区域
土壤盐渍化程度、型和特征等进行了分析和探讨。并根据采样点地下水位、化度、程、被盖度、离海远近
等要素,采用灰色关联度模型,分析了不同盐渍化类型主导的环境要素。结果表明,原生盐渍土含盐量主要受地
下水位、化度和植被覆盖的影响;土壤次生盐渍化主要受离排灌渠远近、下水矿化度和埋深的影响。

Abstract : Based o n field survey and soil sampling data , t he occurring enviro nment and influencing factors of
saline soil s of Yellow River Delta has been described , and t he severit y , classificatio n and characteristics of
ater dept h , total dissolved solids ( TDS) , elevatio n , vegetatio n cover , a grey co rrelatio n model was utilized to
indicate t he main co nt ributor s of soil salinizatio n. A s a result , t he salinit y of p rimary saline soil was mainly
co nt rolled by gro undwater dept h , TDS and vegetatio n cover . The seco ndary saline soil was mainly influenced
by distance to drainage dykes , gro undwater TDS and dept h.
