摘　　要：文章以云贵高原的人工草地为研究对象，分析了草地资源分布的时空特征及增长动态，运用生物控制论方法组建了牧草资源种群保护性利用的最大持续产量模型，并以试验为例，确定了具体的保护指标与放牧管理措施，研究了单播人工草地的最优控制模型与放牧对策，进行了相应的定量分析。With the sown pastures on the Yunnan Guizhou plateau as the subject of this study, the local grassland resources were examined for identifying their characteristics of time spatial distribution and growth dynamics, and a model of biological control was established for utilising the resources under sustainable maximum yield and protection of forage species. Based on a series of experiments, a set of practicable criteria for resource protection and corresponding measures for grazing management were determined, and quantitative analyses were made on optimised control model and grazing schemes for sown pastures of a single species.
