Abstract:
Based on data-debase and the object-oriented technology, the evaluating models of ecosystem services value are abstractly analyzed. The direct marketing method. a new method of ecosystem services value evaluation, is adopted, And using the improved natural vegetation NPP (net primary production) model, the computer evaluation program and the evaluation flow of object-oriented ecosystem services value of are built up. Finally, an automatic evaluation system that can easily calculate a batch of ecosystem values is designed. Through computing the NPP of plentiful diverse plants in the suburban area of Tongchuan City, the feasibility and the reliability of this automatic evaluation system are proved.
