摘要

研究了福州市不同功能区城市土壤的pH值、有机质和磁化率。结果表明

福州市土壤pH值以中性和碱性为主

可能是受城市化过程中碱性废弃物排放的影响所致;土壤有机质含量总体较高

各功能区的变化规律为:工业区>商业区>城市风景区>生活文化区

反映了土壤有机质含量的增加与高强度人类活动有直接关系;土壤磁化率值总体偏高

代表着福州市土壤普遍受到一定程度的重金属污染

不同功能区的磁化率特征表现为:工业区>商业区≥生活文化区>城市风景区。不同功能区土壤的pH值、有机质和磁化率三者之间基本不存在相关关系

这与自然土壤有较明显的区别。

Abstract

A study on the pH value

organic matter and magnetic susceptibility of urban soil in different function zones was conducted systematically in Fuzhou City.The result shows that the pH of the soils ranged from neutral to alkaline

which may be contributed by the discharge of alkaline waste during the urbanization process.The contents of soil organic matter were high generally;the industrial zone

commercial zone

scenic zone and cultural zone had high to low organic matter content

respectively

reflecting the direct relationship between soil organic matter content and human activities.The overall high magnetic susceptibility values indicated that the soils in Fuzhou City subject to substantial heavy metal pollution.The magnetic susceptibility of the function zones in order is industrial zone>commercial zone≥cultural zone>scenic zone.There is no correlation between the three variables

which is significantly different from the physiochemical properties of natural soils.
