摘要: 将因子克里格分析方法应用于海底沉积物重金属元素空间多尺度变化的研究中,分析了北部湾东北部表层沉积物中7种重金属元素,Ni、Cu、Zn、Pb、Cr、As和Cd的空间多尺度结构特征,识别并分离了重金属元素不同尺度的空间变化,并探讨了各个尺度上重金属的物源及控制因素。结果显示,研究区重金属存在块金效应、变程为30km的球状结构(短变程尺度)和变程为140km的球状结构(长变程尺度)等三种尺度的空间结构,并拟合了研究区7种重金属元素的线性协同区域化模型。短变程尺度上,7种重金属元素的空间分布表现为"点状"或"条带状"的局部尺度的空间变化特征;长变程尺度上,7种重金属元素的空间分布反映出"片状"的区域尺度的空间变化特征。局部尺度上,Zn、Cr、Ni、Cu、Pb和Cd等元素主要源于海南岛、雷州半岛、广西大陆等陆地母岩物质,其空间分布特征受到了沉积物粒度的控制作用;而As主要受到海南岛、雷州半岛的人为污染成分的影响。区域尺度上,Zn、Cr、Ni和Cu主要来源于雷州半岛、海南岛的母岩物质,其次为广西大陆;As主要来源于海南岛的母岩物质,其次为雷州半岛、广西大陆。这些重金属元素在北部湾终年逆时针大环流的控制下,进行搬运、迁移并沉积在"汇聚中心",形成了研究区重金属元素区域尺度上NWW-NNW向的分布格局;而As不同于其他元素的亲陆的NNW向分布特征,主要源于其不同的地球化学行为。Abstract: Factorial kriging analysis is applied to the research on the spatial multiscale variability of heavy metals in submarine. It is used to analyze the multiscale spatial structures of seven heavy metals, Ni, Cu, Zn, Pb, Cr, As and Cd in the surface sediment from the northeastern of Beibu Gulf, identify and separate spatial variations at different scales of heavy metals, and discuss the provenance of heavy metals and the influencing factors. The results show that the existence of three-scale spatial variations those consist of nugget effect, a spherical structure with range of 30 km (short-range scale) and a spherical structure with range of 140 km (long-range scale) in the linear model of coregionalization fitted. The spatial distribution features of seven heavy metals at short-range scale reflect "spot-like" or "stripe-like" local-scale spatial variations; the spatial distribution features of the seven heavy metals at long-range scale represent "slice-like" regional-scale spatial variations. At local scale, Zn, Cr, Ni, Cu, Pb and Cd are derived primarily from parent materials of Hainan Island, Leizhou Peninsula and Guangxi land, whose spatial distribution characteristics are controlled by granularity of sediments, while As is influenced dominantly by human pollution components from Hainan Island and Leizhou Peninsula. At regional scale, Zn, Cr, Ni and Cu originate primarily from parent rock materials of Leizhou Peninsula and Hainan Island, secondly from Guangxi land; As originated primarily from parent rock materials from Hainan Island, secondly from Leizhou Peninsula and Guangxi land. These metals are transported and migrated with sediments dominated by the anticlockwise circulation of Beibu Gulf year-round, deposited in "convergence center", forming the whole sedimentary pattern in direction of NWW-NNW at regional scale. The difference in distribution type between As and other metals at regional scale is mainly due to their different geochemical behavior.
