Modeling Soil Nitrogen Mineralization Dynamically Based on Gis

Industrialization of human society and the expanding human space inspired the nitrogen cycling, that have caused environment problems. Nitrogen fertilizer application generates the most activity nitrogen. The nitrogen mineralization have been researched in the soil dynamic model in Yizheng county, then the simulation models have been realized it in the program of Grid block of ArcGIS Workstation. That layout the grids images of soil organic nitrogen containments and the grids images of other organic nitrogen containments in the special times, then though analysis the results in time got a probable future spatial nitrogen containments varieties in the whole area.
