对查干淖尔湖滨地区的植被分布及优势种的种间关联进行了研究,结果表明:湖滨植被自湖边向外可分为若干个不同的植被区域,呈现出“纵向上分带,横向上分区”的特点。随着水分的减少,植物多样性呈现先增加之后又有所减少的趋势。中-湿生植物群落建群植物以单优建群种为主,旱生植物群落以多优建群种为主。7种优势植物种间整体关联性为显著的负相关,由其组成的21对成对植物间也以负相关为主,不同物种间相互作用较弱,表明本区域植被处于演替中的初级阶段,群落环境较不稳定。本研究可为查干淖尔湖的生态恢复和植物多样性保护提供理论依据。
對查榦淖爾湖濱地區的植被分佈及優勢種的種間關聯進行瞭研究,結果錶明:湖濱植被自湖邊嚮外可分為若榦箇不同的植被區域,呈現齣“縱嚮上分帶,橫嚮上分區”的特點。隨著水分的減少,植物多樣性呈現先增加之後又有所減少的趨勢。中-濕生植物群落建群植物以單優建群種為主,旱生植物群落以多優建群種為主。7種優勢植物種間整體關聯性為顯著的負相關,由其組成的21對成對植物間也以負相關為主,不同物種間相互作用較弱,錶明本區域植被處于縯替中的初級階段,群落環境較不穩定。本研究可為查榦淖爾湖的生態恢複和植物多樣性保護提供理論依據。

In this study, the vegetation distribution and interspecific association of dominant species in Chagannoor lake was analyzed. The results showed that, Outward from the lakeside, vegetation can be divided into several different vegetation zones. The vegetation showed a feature of "longitudinal zonation and horizontal partition" pattern. With the reduction of water, plant diversity changed from less to more, the outermost layer has declined slightly. Mesophydrophyte plant communities' constructive species mainly to be monodominant and xerophyte plant communities' constructive species are more polydominant. The seven dominant species was overall correlation significant negative and the 21 spices-pairs were also mainly negative correlation, interactions between different species was weak which indicated that the vegetation of the area is in the early stages of succession, and the environment of community was less stable. Puccinellia was higher negative correlation with other plants, and duriuscula was higher positive correlation with other plants. This study provides a theoretical basis for ecological restoration and conservation of plant diversity Chagannaoer Lake.
