Research On Campus Plant Landscape Evaluation Of Hunan University Based On AHP Method And SBE Method

The impact of the rapid development of higher education is the rapid growth of campus scale,the number of students and the rise of school campus construction.Most colleges and universities tend to neglect the construction of campus environment during the construction process.Hunan University also faces such a The problem,the pros and cons of the plant landscape is an important factor affecting the quality of the campus environment.The design of the campus plant landscape and how to evaluate the campus plant landscape has become a concern.This paper takes the campus landscape of Hunan University as the research object,and takes the green space on the campus of Hunan University as the research area.Based on the comprehensive systematic study of the campus plant landscape and plant landscape evaluation theory,the basic theory of campus plant landscape construction is integrated.A comprehensive,microscopic and scientific landscape evaluation of the plant landscape of Hunan University campus was carried out.Firstly,the floristic composition,life-type structure,plant use frequency and ecological structure of plant communities on campus were systematically analyzed.Quantitative comprehensive investigation and analysis of the plant landscape of Hunan University campus were carried out.Different evaluations were conducted for different types of evaluators.In this method,64 non-professionals were invited to use the SBE method to evaluate the results of the SBE method,and the SBE values were ranked in 18 plots and the plant community examples were evaluated.Using the Analytic Hierarchy Process(AHP)to evaluate,comprehensive expert opinions,predecessors’ research results and actual conditions,the campus plant landscape evaluation system of Hunan University was constructed: the evaluation of the campus landscape of Hunan University as the target layer A,with three major criteria Layer B and 11 factor layers C,and then integrated the data of the evaluation matrix using the evaluation matrix of each evaluation factor to obtain the weight values ??of each criterion layer and factor layer,and constructed the campus plant landscape evaluation model of Hunan University,invited 23 The professional scored the scores,and the results of the AHP method were obtained,and the landscape grades were divided for each plot.The results showed that Hunan University campus plant landscape quality level are only in passing,the whole plant landscape quality is not high.After the evaluation method is completed,the AHP method and the SBE method are used to test the W-coincidence coefficient and analyze the difference of the evaluation trend,and the comprehensive evaluation results are obtained by combining the two evaluation results.The evaluation results passed the consistency test and were basically the same in the general trend.The two methods are effective and reasonable for the evaluation of the plant landscape of Hunan University campus,and have a good evaluation effect.At the same time,the evaluation trends and differences of the two evaluation methods are carried out.The analysis shows that the AHP method is more inclined to the more comprehensive plant landscape based on the professional point of view.The SBE rule is based on the user’s point of view and is more inclined to the visual aesthetics of the plant landscape.Finally,based on the field research and the evaluation methods of the two evaluation methods,combined with the current situation and characteristics of the plant landscape of Hunan University campus,the macroscopic level proposed the campus plant landscape of Hunan University from three aspects: landscape ecological function,landscape aesthetic function and landscape behavioral psychological function.Optimization approaches and recommendations,the micro-level proposed a targeted plant landscape optimization strategy in the face of specific evaluation plots.
