Abstract

Abstract The flora of vegetation cover of sod-lithogenic soil on loess loams was studied at a reclaimed site in the Nikopol manganese-ore basin. The control site is located on the black soil of the steppe area. The species composition of plants was studied in both sites annually for three years. Ecological analysis of the flora was carried out according to Raunkiaer’s system of life-forms and Belgard’s system of ecomorphs. It has been established that the floristic composition on the reclaimed site is significantly poorer than that of the steppe site. The reclaimed site was found to be have fewer species and a smaller number of families. The comparative inconstancy and dynamism of floristic composition on reclaimed soil is shown. The reclaimed ecosystem is distinguished by a significant share of the participation of annual and biennial plant forms. This indicates the anthropogenic transformation of the vegetation cover of the reclaimed soil. Also, a distinctive feature of the reclaimed soil flora is the smaller number of ecological groups of species. Such groups are united according to the ecological optimum to one of the environmental parameters.

复垦土壤植物区系多样性、动态及生态学分析

摘要在尼科波尔锰矿盆地的一个开垦地上，对黄土壤土上的草皮成石土植被覆盖区系进行了研究。控制点位于草原区的黑色土壤上。每年在这两个地点对植物的物种组成进行为期三年的研究。根据Raunkiaer的生命形态系统和Belgard的生态形态系统对植物区系进行了生态学分析。已经确定，开垦场地的植物区系组成明显比草原场地的植物组分差。开垦后的场地被发现物种较少，科数较少。显示了再生土壤植物区系组成的相对变化性和动态性。再生生态系统的特点是每年和两年一次的植物形式占很大比例。这表明开垦土壤植被覆盖的人为变化。此外，再生土壤植物群的一个显著特征是物种的生态群数量较少。这些群体是根据其中一个环境参数的生态最优值而结合在一起的。
