Paper Abstract

Based on the laboratory analysis result of heavy metals in geo-authentic productive area's soil of Ligusticum chuanxiong Hort., this paper studied the spatial variability and the geographic distribution of the heavy metals in the soils of fifteen specimens by the GIS and BP-Kriging, such as Cu, Pb, As, Cr, Hg, Cd .The results showed that the way of BP-Kriging could carry out a relatively accurate spatial analysis to even a small group of data and manifest the structural or regional character and the randomicity of the elements in soil. By the research, it could provide a scientific way for the distribution and GAP production of Ligusticum chuanxiong Hort. growing in Sichuan province.
