摘要/Abstract

摘要： 东北羊草草原3种植物群落土壤过氧化氢酶活性的季节变化曲线基本都呈抛物线型,虎尾草群落季节变化幅度比羊草群落和碱茅群落大,造成这种现象的原因可能是“种子效应”.对不同土层深度过氧化氢酶活性与环境因子的相关分析表明,土壤过氧化氢酶活性随着土层的加深而递减,并与降雨量和大气温度有较强的相关性,且受土壤温度和土壤含水量的协同作用;此外,土壤过氧化氢酶活性与地上植被明显相关,可以反映出植物群落的生长状态.

Abstract: The seasonal dynamics of soil catalase activity of three different plants communities in Leymus chinensis grassland in northeast China were in a parabolas shape. The seasonal variation of Chloris virgata community was greater than those of Leymus chinensis community and Puccinellia tenuiflora community, and "seed effect" might be the main reason. The correlation between the activity of soil catalase in different soil layers and environmental factors were analyzed. The results showed that the activity of soil catalase was decreased gradually with depth of soil layer. The activity of soil catalase was closely correlated with rainfall and air temperature, and it was affected by soil temperature, soil moisture, and their interactions. The correlation between the activity and aboveground vegetation was very significant, and the growing condition of plant communities could be reflected by the activity of soil catalase.
