| 摘 要： | 土壤中cd元素空间分布的研究是土壤科学的重要内容，也是土壤环境污染评价与防治的重要依据。空间变异研究中最为常用的克里格插值法能够较为精确的进行空间估值，但由于它的低通滤波性，使得对于较高数值的异常点往往不能正确估计。而异常区域的元素分布状况恰是环境污染评价与防治最为关注的。因此，本文采用多维分形地统计学方法，对大兴地区的镉元素进行了空间插值分析。结果表明，该方法能较好的反映cd元素的空间分布奇异性。 |

| Abstract: | As an important part in soil science,analysis of spatial distribution of Cd in soil is a basis for evaluation and control of soil environment pollution.Kriging interpolation method,which is most commonly used,could make a precise evaluation.However,when evaluating abnormal distribution of elements in the region that are most concerned with the evaluation and control of environmental pollution,Kriging interpolation,due to its low-pass filter,is unable to correctly estimate the outlier.Therefore,this paper ma... |
