摘要: 测定了浙江安吉6种林分类型(茶园、毛竹林、湿地松林、灌木林、落叶栎林、常绿苦槠-青冈混交林)、4个层次(0—10、10—20、20—40、40—60 cm)土壤对Cu2+的吸附量,并探求土壤有机质含量、CEC、pH值及颗粒组成与Cu2+吸附量之间的关系。结果表明,落叶栎林对Cu2+的吸附量最大,灌木林次之,茶林与常绿苦槠-青冈混交林居中,毛竹林与湿地松林吸附量最小;不同层次土壤对Cu2+的吸附量随土层深度增加而减少。土壤有机质含量和CEC是影响供试土壤Cu2+吸附量的主要因素。建立了土壤有机质含量和CEC与土壤Cu2+吸附量的关系模型。

Abstract: Cu2+ adsorption of 24 soil samples gathered out of 4 soil layers(0—10、10—20、20—40、40—60 cm) of 6 different types of forests in Anji,Zhejiang were determined to explore relationship of Cu2+ adsorption with organic matter content,CEC,pH and particle composition.Results show that in terms of Cu2+ adsorption the six types of forests are in the order of broadleaved deciduous forest>shrubbery>tea grove>broadleaved evergreen forest>bamboo grove>pine forest.Cu2+ adsorption decreases with the depth of the profile.Organic matter content and CEC are the two major factors affecting soil Cu2+ adsorption.Based on the findings,a model is established to illuminate the relationship of Cu2+ adsorption with organic matter content and CEC.

Key words: soil, copper, forest type, heavy metal, physical and chemical property, adsorption, affecting factor
