摘　　要：该文以系统工程组装理论为指导，以牧草生长发育有关理论与实验为基础，建立牧草气候生产潜力模型。以黄土高原几个代表性点的实测资料对模型进行检验，结果表明：该模型有较高的可信度，而且操作简单，并用该模型初步分析了光温水及牧草盖度对天然草场生产力的效应。Under the guidance of the combinatorial theory of the system engineering,we have de-veloped a model for pasture climate potential productibility on the basis of the expcricnce and therelevant theories of the pasture growth and development.It has shown that the model is feasible op-eration and truthful through the comparing tests with actual data and the computering data of sometypical sites in Loess Plateau. At same time,we primarily analysis the effect of radiation,tempera-ture,water supplying and pasture cover on the climate productive potential and its climate potentialproductibility.
