摘要: 以北京东郊污灌土壤中铜和铅为例,探讨了条件模拟中的转向带方法在研究土壤中重金属空间分布特征的应用,从统计特征、空间结构等方面考察了模拟结果,分析了误差产生的原因.结果表明,空间模拟方法可以很好地再现土壤重金属含量的空间结构特征,为揭示土壤重金属含量的空间结构特征提供了一个有力的工具.应用该方法有助于了解土壤、水体和大气环境中各种物质的来源、迁移转化路径以及最终的分布特征,从而为环境评价、规划及解决有关问题提供技术支持.

Abstract: Geostatistical simulation techniques are widely used in studying spatial phenomena. The purpose of this study is to make an experimental study in applying this technique to understand the spatial distribution of copper and lead in wastewater irrigated agricultural soil in the eastern suburb of Beijing. The results showed that the simulation is efficient,because it fits to the main characteristics of the revealed reality of the spatial distribution of these elements. Geostatistical simulation could play an important role in regional environmental and ecological studies.
