Relationship Between Plant Communities and Environment Factors in Riparian Zone Along Ziya River
[Objective] The study aims to find out factors that influence the plant community structure and distribution pattern in the riparian zone along Ziya river
and provide references for related research. [Methods] In June
2013
we investigated plant community structure and six environmental factors in 94 plots including altitude
levee type and land use type outside the levee in the Ziya river system. [Results] Totally
we found 249 species
which covers 51 families and 166 genera
of which
199 species covering 43 families and 135 genera were found in the mountain regions in the mountainous region and 36 species covering 22 families and 35 genera were found in the plain. Phragmites australis
Artemisia mongolica
Vitex negundo
Artemisia annua were the dominant species in the mountain rivers and P. australis
Amaranthus retroflexus in the plain rivers. The species richness in mountain was significantly higher than that in the plain areas. [Conclusion] The altitude and the land use type outside levee significantly associated with the plant community structure. Hydrothermal conditions and human activities are the main factors affecting the vegetation composition and spatial distribution.
