摘要/Abstract

摘要： 通过对典型环境功能区张士灌区包气带剖面样品和含水层样品的分析检测，比较和总结了菲的垂向分布特征，研究了总有机碳、粘粒含量、土壤含水率对菲垂向分布与迁移的影响规律和机理。对具有代表性采样点的研究表明，菲总含量在剖面中的变化趋势总体上随剖面的加深而降低,以犁底层为界，表层土壤（5～20 cm）菲含量随剖面深度变化平缓。同时分别对菲含量与总有机碳、土壤粘粒含量、土壤含水率进行二元相关分析，计算出的Pearson系数表明：土壤中总有机碳、土壤粘粒含量是影响菲垂向迁移的重要因素，而土壤含水率对菲垂向分布影响不大。同时利用SPSS的因子分析法进一步确定总有机碳是制约菲垂向运移的主要因素。

Abstract: The rule and mechanism that total organic carbon, clay content and soil water content affected PHEs’ vertical distribution and migration were shown by testing and analyzing soil samples from vadose zone and aquifer in the typical environment district-Zhangshi irrigated area. The research of representative sampling spots indicated that the tend of the total content of PHEs decreased generally with the depth of the profile section; while that of upper soil varied slowly from 5 cm to 20 cm beyond the plough pan.Then,the relationship between PHEs and total organic carbon, clay content and water content was analyzed separately by two variable correlation analysis, and the findings calculated by Pearson coefficient demonstrated that the total organic carbon, clay content were the important factors influencing the PHEs’ vertical distribution and migration, but soil water content was neglected. SPSS factor analysis is further used to ensure that total organic carbon is the key factor which limits the PHEs vertical distribution.

Key words: Zhangshi irrigative area, phenanthrene (PHEs), total organic carbon (TOC), clay content, soil water content, vertical distribution and migration
