摘要
本文通过对东北羊草草原不同羊草群落内各种群间生态位重叠关系的研究,揭示出羊草群落各种群对不同环境资源的利用能力及对生态因子的适应能力和占据空间的能力。定量化地描述了种群间的共存关系和竞争机制,通过生态位再现了羊草群落现有分布格局及各种群对有限环境资源的利用。
In this article, ecological niche overlap of several populations of different leymus communities in Northeast leymus plain was studied and revealed utilization capability of several populations of different leymus communities on environmental resources and adaptability, spatial position capability on ecological factors. There are some numerical describes about species concurrent and competitive strategy of several populations. The research result reappeared current distribution structure and finitude environmental utilization of several populations by ecological niche and put forward rationalization proposal of improvement leymus plain.
