“森林－竹子－大熊猫”三位一体生态系统维持机制数学模型研究
Studies on the Mathematical Model of Maintenance Mechanism for “Forest-bamboo-panda” Trinity Ecological System
摘要
Abstract
A delay differential equation model on the relation between the forest, bamboo and giant pandas was es⁃tablished. The conditions for the permanence of the system were obtained by analyzing the variable coefficient differenti⁃al systems with time delay and stage structure. The characteristics of this paper are to verify the maintenance mecha⁃nism of the stability of the forest, the bamboo and the giant panda trinity system which was presented by Junqing Li et al. and to analysis the factors that restrict the stable development of the system, which provides theoretical basis for the giant panda habitat protection.关键词
