【摘要】 研究了松嫩盐碱地羊草群落地上生物量的季节动态，结果表明：其最大生物量出现在8月份，而相对增长速度6月份明显高于其它月份。羊草群落的地上生物量构成主要来自羊草，其它草类产量甚微。从季节动态上看，羊草群落的地上生物量与月均气温，降雨量没有明显相关关系，而与蒸发量呈显著相关，体现了盐碱草地的水份关系特点。更多还原

【Abstract】 Seasonal changes of biological of the part above earth sneurolepidium chinensis community is a mono -speak curve, its maximum biolgical yield appeared on August, but relative increase rate of which on June is evidently higher than other month. Main constitute of biological yield of other grass is extremely few. According to seasonal,changes, there were no relationship between the biological yield of the part above the earth of A. chinensis community and monthly average temperature of rainfull , but there was significant relationship between the biological yield of which and capacipy of evdaporate. which showed the trait of water relations of alkalized grassland.更多还原
