摘要: 研究了松嫩草原土壤动物优势类群黄墩蚁对羊草群落和羊草+虎尾草群落组成及生物量的影响.结果表明,黄墩蚁改变了其生境中的植被组成,两群落中的羊草密度增大,结穗率降低,但重量增加.受其影响,羊草和虎尾草的高度明显较大,地上生物量和地下生物量明显增加.

Abstract: The author studied the Leymus chinensis community and the Leymus Chinensis+Chloris virgata community under the influence of the dominant soil animal colony Lasisus flavus. The results revealed a vegetation compostion change by Lasisus flavus. The density of the Leymus chinensis in the two communities became higher, and the fruit was less, but heavier. Under the influence, the height of Leymus chinensis and Swartz became higher clearly, and so was the aboveground biomass and underground biomass.
