| 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、类型和特征等进行了分析和探讨。并根据采样点地下水位、矿化度、高程、植被盖度、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、矿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、地下水矿化度和埋深的影响。

| Abstract: | Based on field survey and soil sampling data,the occurring environment and influencing factors of saline soils of Yellow River Delta has been described,and the severity,classification and characteristics of soil salinization were discussed. According to the environmental variables at sampling points,e.g. groundwater depth,total dissolved solids (TDS),elevation,vegetation cover,a grey correlation model was utilized to indicate the main contributors of soil salinization. As a result,the salinity of primary sa... |
