| 摘 要： | 在兼顾吉林省公主岭地区土壤类型与样点分布的相对均匀性的前提下 ,采集黑土、黑钙土和草甸土等土壤耕层 (0 -2 0cm )样品 70个 ,测定其全砷 (As)、铬 (Cr)和锌 (Zn)含量以及其它主要理化性质。采用经典统计学与半方差函数拟合相结合的方法 ,研究了土壤砷、铬和锌含量的空间变异性。根据半方差函数的拟合结果 ,在ArcViewGIS软件的支持下 ,编制Scripts进行克里格插值 ,以此来揭示该区域土壤砷、铬和锌含量的空间分布规律 ,并探讨这些重金属元素与主要土壤理化性质的关系

| Abstract: | Seventy soil samples (0-20cm)were collected in Gongzhuling Area. the Arsenic, Chromium ,Zinc contents and primary properties of these soils were tested. The spatial variability of Arsenic, Chromium and Zinc Contents were studied based on the mathematical statistics and Geostatistics methods. Based on the models of semivariance fitness, we programed AVENUE SCRIPTS with ArcView GIS software to proceed kriging interpolator to discover the distribution law of the three heavy metals .At the same time, the relationship between heavy metal contents and primary soil properties were also discussed. |
