Application of Statistical Geo-Spatial Information Technology to Soil Stratification

Geo-statistical Distribution of Heavy Metals in Karoon River’s Soil by Geographic Information System

Introduction: Soil has an important role in nutrient cycle and an important function in storage, refinement, and movement of nutrients for the living and non-living parts. Soil pollution of heavy metals and elements is one of the common pollution impacts of human activities, especially industry. Realization of distribution pattern of these elements and their anthropogenic sources is a major par...

Urban Geo-spatial Information Updating Technology

The present situation is a life of basic geographic information. Only when basic geographic information has to renew continuously can it reflect truly the present situation of the nature and cultural features. On the base of deep studying, this paper provides the practical solution of the urban geo-spatial information updating quickly facing the rapid development of our country city building. T...

A new method to consider spatial risk assessment of cross-correlated heavy metals using geo-statistical simulation

The soil samples were collected from 170 sampling stations in an arid area in Shahrood and Damghan, characterized by prevalence of mining activity. The levels of Co, Pb, Ni, Cs, Cu, Mn, Sr, V, Zn, Cr, and Tl were recorded in each sampling location. A new method known as min/max autocorrelation factor (MAF) was applied for the first time in the environmental research works to de-correlate these ...
