[Objective] The development and utilization of selenium rich land resources in Lishui District of Nanjing City were studied in order to provide scientific reference for developing local characteristic selenium enriched agricultural products industry.[Methods] On the basis of sampling and testing of soil chemical properties at Lishui Distriat

analysis of statistics and interpolation of soil selenium content by ArcGIS

selecting the most appropriate model and interpolation method

according to the prediction of the soil selenium sample point data

literature data and the actual situation of Lishui District

selenium enriched land was graded to understand its selenium spatial distribution. Areas that are suitable for planting selenium-rich agriculture products and the species were maped and listed.[Results] There is approximately 4.25% of the land resource of selenium rich in Lishui District

which distributed in townships in the form of block or spot

which can be developed as the planting land of the selenium rich agricultural products by combining the soil acidity and alkalinity.[Conclusion] The Gauss model in the common Kriging method can well fit the situation of soil rich selenium in Lishui District

and the selenium rich land resources in the study area have great development space and utilization value. It is necessary to make rational planning and provide basis for the development of regional characteristric agricultural products market.
