Numerical Simulation of Niche Fitness Process of Plants in Sandy Area

The plant niche fitness theory and its simulationi method in this paper are nwe developments of the niche theory and its quantitative analysis method. Taking plants in sandy areas as objects for research, we constructed a theoreitical niche fitness pattern and its computational formulae as well as the simulation method of water fitness process. On the basis of expermiental results, we have done computational analyses and numerical simulation concerned. The simulation result has a very high accuracy, and it tallies with the observed result. This achievement movides the construction o artificial forests in sandy areas with a good quantitative basis.
