제주도 한라산 노루에 관한 시스템적 접근

Increasing of the number of Roe Deer in Jesudo is regarded as an direct cause of the damages of Roe Deer - i.e. damages of crops and trees by Roe Deer and traffic accidents between human and Roe Deer. But, no study of the number of Roe Deer in Jejudo has been found and never has been progressed it and nobody convinces about the total number of Roe Deer in Jejudo. In this paper, we focus at the moving pressure which enforces Roe Deer to move the other places. Moving pressure is appeared when the habitat environment destruction of Roe Deer and it forces Roe Deer in hilly section to move the middle mountains section and the low section. This moving pressure promotes the moving of Roe Deer to the other places and then the total number of Roe Deer in new places are increasing. High density of Roe Deer makes the habitat environment bad and increases the competition of Roe Deer. These patterns are repeated continuously. The habitat environment of Roe Deer is related with human life area very closely. We should keep and preserve our nature and environment, and if we develop our nature then we must consider our ecosystem in all aspects. It's the most important thing to us and Roe Deer and other living things.
