| 摘 要： | 通过对郑州黄河滩地植物群落调查,结果表明:郑州黄河滩地植被有148种,隶属于42科109属,除了一个蕨类植物木贼科外,其余全为被子植物。科和属的地理成分分析表明,研究区植物区系以温带成分为主,热带区系成分也占相当大的比重。郑州植物区系是黄河植物区系纵向连续体的一部分,对上下游河段植物区系有着重要的顺承作用。滩地自然更新的灌草形式维持着较高的物种多样性,其次为人工林地。

| Abstract: | Vegetation communities in Yellow River bottomland were investigated.Result showed that there were 148 species of plant were recorded,belonging to 109 genera and 42 families,and all of them were angiosperm except for one fern.Geographical element analysis of both family and genera revealed that temperate elements took dominant position,and tropic elements accounted for largish proportion.An obvious connection of this flora was found in longitudinal direction with its upper and down reach flora,which revealed the continuity and integrity of Yellow River flora.The natural reproduction shrub and grass maintained higher multiple level than the forest land. |
