摘要

文章用细胞自动机研究群落的演替过程。根据从1983年围封内蒙古典型草原后连续11年定位监测的数据,建立了一个描述在过大牧压下退化的典型草原植物群落封育后恢复演替的模型。用计算机对模型进行仿真,仿真的结果符合实测群落恢复演替的动态趋势,从而验证了建模时所提出假设的正确性。进而用这一模型模拟草原的退化过程,深化对草原退化和恢复演替的机理的认识。

Abstract

According to the monitoring data under fenced condition in typical grassland of Inner Mongolia from1983to1993,a cellular automation model is established to discuss the typical steppe grassland community succession.The computer simulation result is close to the dynamic tendency of actual community restoration succession,so the hypothesis that proposed for estab-lishing the model proves to be correct.Furthermore the grassland degenerated procedure can al-so be simulated using this model,and the cognition to the degenerated grassland and re storation procedures is also deepened.

Key words： typical grassland; degenerated community; restoration succession; computer simula-tion
