セルオートマトン法によるヤマトシジミを中心とした生態系モデルの開発

抄録

The purpose of this paper is to develop an ecosystem model by using cell automaton (CA). First, we simulated the distribution of Corbicula japonica prime for a long term, and then considered the change in the distribution by the change of environmental factor. Our model is applied to Shinji Lake in east part of Shimane Prefecture.
The observation results were compared from distribution with the calculation result. The result showed a comparatively good agreement. It was able to be reproduced the distribution of the Corbicula japonica prime in an extremely high density in the coast region. It has been understood that the change of the Corbicula japonica prime has strongly received the influence of the change of an environmental factor.
