Study On The Waterfront Plant Community Landscape Of Diannong River In Yinchuan

In this study,under the climatic environment of arid and semi-arid Northwest China,the Yinchuan City,a wetland city in the Northwest China,was selected as the research area.Based on the statistics of the main plant types in the waterfront green space of the ’Diannong River"in the main city of Yinchuan,114 types of trees,72 types of vines and shrubs,49 types of ground cover and 7 types of lawn plants 22 types of wetland plants.By dividing the plots of the green land along the waterfront,16 representative plant community plots were selected,and the air negative(oxygen)ion content,temperature,humidity,PM2 in different seasons and different time periods in the plot were selected.5 and other factors for data collection,analysis of the impact of different environmental factors on the waterfront plant community,it is concluded that although most types of waterfront plant communities along the Diannong River are relatively simple,the community stability is good.In different seasons,the waterfront plant community of the Diannong River presents different landscape appearances;through the beauty evaluation(SBE)of the plant community landscape within the sample plot,the sample plot S3(QCS community structure)is obtained,S4(QGS community structure),S10(QGS community structure),S16(QGS community structure)as the representative of the four community types of plant community landscape viewing degree is highest,SBE beauty degree evaluation value is the best.At the same time,it is concluded that in terms of spatial layout,vertical performance,and landscape ecological benefits,the multi－level structure community type of arbor,shrub and grassland is the most stable,and has the most seasonal variation and richness.Finally,combined with the research results,this paper gives suggestions on the waterfront plant community planting model in the urban waterfront green space ecological construction process in Yinchuan City.
