A SIMULATION ANALYSIS ON ROTATION GRAZING SYSTEM OF SUMMER-AUTUMN PASTURE IN AN ALPINE MEADOW ECOSYSTEM
高寒草甸放牧生态系统夏秋草场轮牧制度的模拟研究

An expert system,Grazing Manager of Alpine Meadow Ecosystem 1(GMAME1),has been structured to facilitate stochastic evaluations of rotation grazing system on alpine meadow pastures,Qinghai Province,China.A model grazing on summer-autumn meadow (from 1 June to 30 October)was originated to provide a practical method for estimating the effects of grazing frequency, grazing duration and grazing pressure on GMAME1.The model provides 31 different attributes for characterizing the performance of a grazing system.
