| 摘 要： | 基于香港地区51个剖面土壤和44个表层土壤中总硒量的分析,对香港土壤硒含量、分布及其影响因素进行研究.分析结果表明,香港土壤总硒量变幅在0.07～2.26 mg kg-1,平均含量为0.76 mg kg-1,在湿润铁铝土中的硒含量最高,平均为1.05 mg kg-1,含量最低的为旱耕人为土,平均为0.45 mg kg-1;在土壤剖面中硒主要分布在心土层和底土层.林地土壤硒含量(1.36 mg kg-1)较高, 农业土壤较低(0.36 mg kg-1).影响香港土壤硒含量及其分布的因素主要是成土母质.土壤pH值、有机质、粘粒和Fe、Al的含量也是影响土壤硒富集与分布的因素.

| Abstract: | The main objective of this project is to study distribution and concentration of selenium (Se) and its affecting factors in Hong Kong soils.Soil samples were collected from fifty-one soil profiles and 44 surface soil layers at 44 sampling sites throughout Hong Kong for analysis of total Se with the aid of the induct ively coupled plasma spectrophotometry.The results indicate that Se was mainly distributed in B and C horizon.Concentrations of total Se in all the soil samples ranged from 0.07 mg kg-1 to 2.26 mg kg-1 (dry wt.), with the lowest and highest concentrat ions recorded in Orthic Anthrosols (average 0.45 mg kg-1, dry wt.) and Udic Ferralisols (average 1.05 mg kg-1, dry wt.) respectively.In terms of land use, the highest and lowest concentrations were recorded in forest soil (average 1.36 mg kg-1, dry wt.), and agricultural soil (average 0.36 mg kg-1, dry wt.) respect ively.The main factor that influences Se concentration and distribution in Hong Kong soils was the parent material.Other soil factors such as soil pH, organic matter, clay fraction, iron and aluminum also played relatively important roles. |
