Abstract
A soil heavy metals information system in Shandong province was constructed based on environment quality assessment modeling technologies for heavy metals contaminated soils. The system integrates the VB. net software, GIS software MapInfo\ MapX and DBMS SQL Server2000. The system includes four main modules: (1) soil type and heavy metals content information management, query and updating, (2) soil heavy metals environment quality assessment (3) the critical value of soil heavy metal pollution and (4) the soil heavy metals environment quality warning. The sampling usage of the system demonstrates that it is of great significance to regional soil heavy metals information management, sharing and decision-making supporting.
