摘　　要：利用海晏县气象站1980-2006年降水、气温、大风日数以及青海省海晏县1980-2006年天然草地平均产草量,采用气候统计学方法和灰色关联法,进行了关联程度分析。结果表明：自80年代以来气候变暖变干,气候因子对牧草产量的影响非常明显,尤其是夏季降水和春季气温关联度最高。Correlative degree of forage yield in natural grassland and temperature and precipitation was analyzed by climatic statistics and grayness relationship methods based on temperature, precipitation, gale days in Haiyan weather station from 1980--2006 and forage yield in natural grassland in Haiyan grassland station from 1980- 2006. The result showed that the weather was more worm and dry , effect of climatic factors was more obvious for the forage yield, especially in summer precipitation and autumn temperature.
