THE STUDY ON ECOLOGICAL NICHE OVERLAP RELATIONS OF SEVERAL POPULATIONS ON LEYMUS COMMUNITY IN NORTHEAST PLAIN

Abstract

Abstract: 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.

Key words: Population, Ecological niche, Overlap
