Landscape Investigation And Evaluation Of Nanning Shishan Park

In this paper,based on Nanning Shishan Park as the research object,according to the theory of landscape elements,the investigation is carried out from five aspects: plant landscape,architectural landscape,water landscape,road landscape and sketch landscape,and the relevant data of each landscape element are collected.The purpose is to lay a foundation for the evaluation of park landscape and the analysis of Park advantages,characteristics and existing problems.Secondly,AHP is used to establish a reasonable landscape evaluation model for the landscape of Shishan park.the purpose is to draw park landscape quality grade,and finally analyze the landscape quality.Finally,by the investigation and evaluation results,the paper summarizes the landscape characteristics and existing problems of Nanning Shishan Park and puts forward preliminary suggestions.The results are as follows:(1)In the plant landscape of Nanning Shishan Park,there are 294 kinds of applied garden plants,belonging to 76 families and 179 genera,among which arbors and bamboos are dominant,Palmae,Gramineae and Moraceae are widely used,forming a unique south subtropical greening landscape;the architectural style of the park is mainly Lingnan style,including pavilions,corridors,bridges,porches and waterside pavilions,etc.,with various forms;water body The landscape is dominated by large area of water,with single water feature,but rich hydrophilic facilities;the sketch landscape includes sculptures,landscape stones,rest seats,signs,signboards,street lamps,garbage cans,etc.,which landscape stones,sculptures and other decorative sketch are used more frequently;the road landscape is mainly in the form of road layout and road pavement,and the road layout in the park is mainly in the form of ring,paving The installation form is mainly composed of integral pavement,block material pavement and pebble pavement,which are decorated with stepping stones.The form is rich,forming a better landscape effect.(3)In this paper,the analytic hierarchy process is used to evaluate the landscape,and the weight value of the criterion layer and the index layer is calculated.The weight values of the standard layer are: plant landscape(0.3645)> building landscape(0.2424)> water landscape(0.1709)> sketch landscape(0.1118)> road landscape(0.1104).Taking Nanning Shishan Park as the evaluation object,a questionnaire was issued to tourists,and the final evaluation score of the park was calculated based on the weight value of each index.It can be seen that the landscape grade of Nanning Shishan Park is grade II and the landscape quality is high.(4)There are many kinds of plant landscape in Nanning Shishan Park.The park is built with bamboo lotus culture,forming a major feature of the park.Lingnan architectural style features prominently,becoming a landmark scenicspot of the park.However,there are still some problems,such as less use of lianas,poor effect of three-dimensional greening landscape;single form of water landscape,general water quality;lack of lighting sketch,and single type,and The landscape effect needs to be further improved according to the above problems.
