【摘要】 对北京西山国家森林公园土壤元素环境背景值进行测定分析,结果表明,土壤中7种微量元素的含量,均与土壤深度、坡位、坡向及植物类型关系密切.本研究结果,可作为土壤环境质量评价、制定土壤环境保护对策和合理利用及管理土壤资源提供重要的参考.更多还原

【Abstract】 The environmental background values of 7 microelements in the natural soil in the Xishan National Forest Park of Beijing have been determined and analysed.The result indicates that the content of the 7 microelements is closely related to soil depth,slope position,slope orienta- tion and vegetation form.The outcome of this study can provide an important refrence for the e- valuation of soil environmental quality,for the formulation of counter-measures of soil environmen- tal protection,and for the rational management and use of soil resources.更多还原
