| 摘 要： | 放牧对羊草草地植被及其土壤环境的影响是放牧演替系列上植物种群规律分布的重要原因。本文从由放牧引起的植被及主要土壤因子变化梯度入手,研究羊草、五脉山黧豆、寸草苔等8种主要植物在放牧衰退演替系列上的分布规律、生态位重叠及主要土壤因子变化对其分布的影响。

| Abstract: | Grazing, which affects vegetation and soils of A. chinense grasslands, is an impoctant factor regulating the distribution of plant populations of its grazing succession sequence. Threugh the changes in vegetation and soils caused by grazing, the distribution of A. chinense, Lathyrus quinquenervius and sedge, as affected by overlaps of ecological niches and changes in soils was studied in this paper. |
