摘要
采用呼伦贝尔牧业气象实验站2000—2009年牧草(干重)产量资料,结合统计分析方法,对鄂温克旗草原牧草产量与气象要素进行了相关分析。结果表明:不同的牧草生长期,产量与光、热、水三大气象要素有着不同的相关关系。采用牧草产量关系密切的气象因子,建立多元回归牧草产量预报方程,制作牧草产量预报。为当地畜牧和草原等部门提供了有效的指导。
By used of the statistical analysis method and the pasture （Dry weight） yield data from 2000 to 2009 in Hulun Buir animal husbandry and meteorology experimental station, the article＇ made correlation analysis between pasture yield and meteorological factors in Ewenki grassland. The results showed that the pasture yield had different correlativity with three meteorological factors of light, heat and water in different growing periods. Using the meteorological factors that were compact with pasture yield to build muhiple regression equation, made pasture yield forecast. It provided effective guidance for animal husbandry and steppe department.
