| 摘 要： | 本文主要建立小麦、大豆两种作物套种共生生态系统的Volterra方程模型．分析该模型得知，此生态系统是相互竞争的，其自身增长率因环境因素而受抑制，且是全局稳定的．其次计算出该生态系统在平衡状态处受到标准扰动之后，向平衡状态恢复的时间，有利套种作物生长的调控。

| Abstract: | In this paper,the authors mainly establish model of volterra equation in ecological symbiotic system of interplanting between wheat and sogbean.The model shows that the ecologic system is competition to each other and the growth rate of system is restrained by the environmental factors.The ecologic system is all stability.The authors calculate the time which restore from inbalance to balance after disturbing in ecologic system balance and it is useful for the growth and control for the interplanting crops. |
