| 摘 要： | 依据青海省铁卜加特业气象试验站观测的多年资料和牧草的生物学特性，根据天然牧草的生育规律及其在不同生育阶段对气象条件的要求和反映，将牧草产量分解成平均经济产量和气象产量，设计和计算综合牧业气象指标－水热指数，并分析牧草产量形成规律，对不同时期的牧草产量进行模拟预报 。

| Abstract: | According to the observations obtained at Tiebujia Animal Husbandry Meteorological Station in Qinghai province,the biological features of natural herbage growth,and the meteorological condition during different growth and development periods,the herbage yield is decomposed into the average economical yield and climatic yield.The animal husbandry meteorological index,or water heat index,is designed and calculated.The formation rule of the natural harbage yield is analysed,and the yield in different stages is simulated.The forecasting model can be used to calculate the total yield,accumulative velocity of yield and the potential maximum yield. |
