The Kuang-ao Degree Of Scenery Of The Waterfront Of Shanshui City

The quality of good living visual environment to bring people spiritual satisfaction is indispensable.Landscape city has always been faced with the coordination between urban construction and landscape wind resources.Based on the theory of landscape landscape,this paper uses the visual sensing mechanism of landscape city and studies the object of landscape city waterfront landscape.Then,in the Guilin Lijiang city section of waterfront landscape sample,the landscape visual space divided four kuang-ao space type and 13 landscape space sequence,using computer image semantic segmentation,field measurement,Python +Open CV,VR panoramic simulation method of the objective index and subjective index evaluation and quantitative,analyzed the subjective and objective index correlation and influence,discusses the landscape city waterfront landscape space of visual sensing mechanism,established the kuang-ao degree evaluation mathematical model,and using the induction relationship expression to sample overall evaluation and classification evaluation.The study results show that:(1)in the correlation between the objective physical elements and the subjective visual perception index,the correlation intensity is relative spatial scale> natural openness> line of sight permeability> color richness> interface closure>mountain visual rate> bridge visibility> revetment hardness> vegetation level> landscape facilities> waterfront trail width> waterfront envelope,and explains the reason why the green vision rate is not significantly related;the correlation intensity of the visual perception and the visual perception index is mystery> richness> clarity> permeability> nature> solution.(2)In terms of the influence relationship,the objective evaluation index of Kuang-ao respectively has different degrees of positive influence and negative influence on the subjective evaluation index of Kuang-ao.(3)The overall evaluation of the urban section of the Lijiang River in Guilin is mainly medium,indicating that the overall waterfront landscape of the urban section of the Lijiang River in Guilin has a small difference in visual perception.A small number of areas have low values,including the surrounding Xiangshan Scenic Area,the waterfront footpath landscape of Mulong Lake and Diecai Mountain,and some landscape space units of Zizhou Park,which have poor visual experience.In the southern,central and northern parts of the study area,the landscape with high value of landscape intensity,and the waterfront landscape had better visual experience,including the landscape on three Bridges and some spatial units of the landscape along the Yangtze river,while the landscape value of scenic landscape and island landscape was generally medium.(4)In the classification evaluation,the landscape on the bridge is high,indicating that the visual feeling of the bridge is good,indicating that the landscape is moderate,while the landscape is better than the landscape;the river landscape is medium,and the continuous view of different sequences is easy to cause aesthetic fatigue;the overall value of Xiangshan landscape is high and low,indicating that the visual feeling is unstable,which needs to be protected and transformed separately.After comparing the evaluation results with the field landscape,it is found that the evaluation model formula can effectively reflect the host-guest sensing relationship,which verifies the rationality of the host-guest sensing mechanism.Finally according to the induction mechanism and mechanism results for reference,for the problems of Guilin Lijiang river waterfront landscape type,from the macro optimization regulation and micro optimization proposed 14 kuang-ao the space visual feeling optimization strategy,for Guilin city Lijiang river waterfront landscape space visual environment optimization provides advice,for Guilin world-class tourism city landscape construction and living environment quality improvement provides a practical reference.
