THE METHOD OF VEGETATION DYNAMIC MODEL USING NEW SPATIAL INDEX “PLANT COMMUNITY CLUSTER”

Abstract

This paper aimed to verify accuracy of vegetation dynamics model with field survey data observed at a low frequency. We developed four rule-based vegetation dynamic models by changing the combination of “mizukoku” vegetation data which was surveyed by national census on river environment.

As the result of study, it revealed that “mizukoku” vegetation data was valid for the definition of succession rule, and using recent 5 years interval data from the past was important for the improvement of the model accuracy.
