Soil is one of essential environmental factors for human survival and development.Proper classification of soil environmental functions enables the utilization and protection of the soil resources to be effective.Based on exploring the protocol of soil environmental function zoning,this paper aims to divide Nanjing City into different levels of soil environmental function zones according to the present land use situation and the potential effect of land use planning on soil environment by the advanced space simulation techniques,such as RS and GIS.Four soil environmental function zones are divided,the problems and protection direction in each zone are illustrated in details.This work will provide strong evidence for regional soil environmental management .
