摘要
通过３年的定位观测，研究羊草草场的植物种群结构和气象环境因素对草场生产力动态的影响。结果表明：羊草占据草场优势比重，表现了较高生产力的特征。气象因素，特别是湿热条件，与牧草生育期的生长和干物质的积累密切相关。
The effects of the structure of plant community and meteorological an d environmental factor ongrassland productivity dy namic of Aneurolepidium chinese grassland have been studied by 3 vears locationobservation. The results showed that the dominant ratio of A. chinese in grassland showed a higherproductivity characteristic. The meteorological factor especially the humidity and temperature conditions areclosely related to the growth and dry matter accumulating during forage developing stage.
