摘要 综述了土壤重金属空间变异的研究方法及其进展,包括地统计学方法、GIS技术、经典统计学、分形理论和空间自相关分析方法在重金属空间分析中的应用,并分析和讨论了这些研究方法的优势和不足。同时,根据当前土壤重金属空间分析采用较多的地统计学方法的应用范围和特点,提出在应用中应考虑各变量在不同尺度的空间特征及其转化,应根据不同的研究内容和研究目标,选择适宜的研究方法。可为土壤重金属污染和土壤重金属的空间变异研究提供资料借鉴和参考。 The research methods of spatial distribution of heavy metals and its development were discussed, which included geo-statistics methods, GIS methods, classical statistical methods, fractal theory and self-regression methods. The advantage and disadvantage of were analyzed. Meanwhile, geostatistics is one of the most important methods for spatial distribution analysis of heavy metals in soil at present. The characteristics of geo-statistics were discussed. And every variable should be considered about spatial characteristics and transform. According to the scale of research area and the research aim, the suitable methods should be chosen. This paper can provide an important reference for soil heavy metals pollution and spatial distribution of heavy metals in soil.
