摘要
研究了高寒草地不同生境土壤种子库的基本特征。结果表明:滩地种子库密度为7546粒/m2,阳坡为5929粒/m2,阴坡为7260粒/m2;三个生境种子库平均密度为6811粒/m2,土壤种子库中有78个种,分属于21科,其中多年生植物占总数的85%。三个生境种子库的物种组成没有显著差异。
Research on characteristic of edaphic seed storeroom of alpine meadow in different ecotope, the results shows that density of seed storeroom of bottomland are 7546 grain/m^2, density of seed storeroom of south facing slop are 5929 grain/m^2 , density of seed storeroom of north facing slop are 6811 grain/m^2, there are 78 species and belong to 21 family, perennial vegetation account 85% of the total. There are not obviously different among the species forms of three ecotope seed storeroom.
