Analysis And Evaluation Of Waterfront Plant Landscape Of Jinji Lake In Suzhou City

In this study,the plant landscape of Jinji Lake waterfront in Suzhou City was taken as the research object,and a large number of relevant literatures were fully retrieved and collected,and a field survey was conducted.The quantitative characteristics and regional composition of the waterfront plant community in Jinji Lake were analyzed from the perspective of ecology.The AHP method was used to evaluate the plant landscape.Based on the current situation,an optimization plan was proposed.The main research contents are as follow:The composition of the plants in the Jinji Lake waterfront area was statistically investigated.The ecological diversity of the vascular plant family,the genus of the genus of the Jinji Lake waterfront,the seed plant family,the genus-related distribution locations and types were statistically investigated.On this basis,The collected data is collated and analyzed.The results showed that there were 201 vascular plants in the Jinji Lake waterfront,belonging to 149 genera of 75 families.Among them,there were9 families,9 genera and 9 species of ferns,59 families,124 genera and 166 species of angiosperms,and 7 families and 16 genera of gymnosperms.Kind.In the composition of the section,the single species accounted for the highest proportion,and the dominant section was obvious.In the composition of the genus,the plant genus containing only one species is the main body,and there are obvious advantages and subordinates.Seed plants appear in a variety of complex geographical distribution areas in all survey areas.The family of tropical components constitutes the main body of the plant family of Jinji Lake waterfront.In the distribution type of genus,the composition of temperate zone is the heaviest,and the composition of tropical zone is slightly less than that of temperate zone,but the difference between the two is not obvious.Both are the key research objects of this project.The AHP evaluation method was used to evaluate the three elements of visual value,ecological efficiency and service function as the criterion layer.A total of 8quantitative indicators and 7 qualitative indicators were used to evaluate 30 models of Jinji Lake waterfront.The landscape was comprehensively evaluated and the scores of each evaluation index were analyzed.Through the analysis,the comprehensive evaluation results of 30 squares were obtained: there was only one I-level plant landscape,16 grade II plant community landscapes,a total of 10 grade III plant community landscapes,and only one grade IV plant community landscape.From this,itcan be seen that the landscape of the II and III plant communities has the highest proportion.According to the above survey,three advantages are summarized,namely,high green rate,extensive application of native tree species,and obvious functional division.The shortcomings include improper plant species,insufficient ornamental plants,and inadequate use of aquatic plants.From the overall perspective,four aspects of optimization suggestions for the waterfront plant landscape of Jinji Lake were proposed,namely,increasing shrub layer and turf area,adjusting plant canopy closure,increasing seasonal plant landscape,and increasing aquatic plants.Finally,the selection of the poor evaluation results to make a specific optimization and transformation.
