摘　　要：根据云贵高原放牧人工草地初级生产特点 ,提出无利用条件下牧草累积、草地净生长速率和草地现存量曲线拟合方案 ,利用这些曲线方程确定放牧限度和预测放牧前后轮牧小区现存量 ,并制定在速生季短周期高频率轮牧和在缓生季长周期低频率轮牧的利用方案。对实例进行计算和分析 。Based on the characteristics of primary productivity of swon pasturtes for grazing use on the Yunnan Guizhou plateau, a simulated scheme for dynamics of biomass, growth rate and standing biomass was put forward. Accoding to the scheme, grazing limits and standing biomass at the beginnign and the end of utilization can be determined. The formulated rotational scheme is featured with short cycles and a high frequency of utilization for the growing season of pastures. The scheme was applied to and modified in practice.
