Vegetation landscape pattern and interspecific association of Chagannoor Lakeside in arid steppe region
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.
