新たな空間指標「群落クラスタ」を用いた植生動態の再現・予測手法の開発

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.
