Changes in interspecific niche relationship of sand-fixing plants in the restoration process of desert ecosystem

Abstract

Abstract: Taking succession time as niche dimension,this paper studied changes in interspecific niche relationship of sand fixing plants in the restoration process of desert ecosystem by analyzing niche volume and niche overlap of species.At the same time,ecological mechanisms of species replacement were investigated via the analysis of their capability in using resources and interacting with other species.This study is of important significance to the sustainable development of desert sand fixing plant community.

Key words: Purple Soil, Arsenic, Form, Availability
