Quantitative Evaluation Of The Spatial Saliency Of Mountain Views In Jinan Blocks Under The Human-centered Scale

Neighbour mountain landscape is a rare natural ecological landscape in many cities in China.The main feature distinguishing it from other open spatial landscapes such as parks and green spaces is that the general view of street view corridors needs to be considered when building.Jinan city is located on the pre-mountain plain and develops in parallel with the southern mountains.The scattered independent peaks and continuous mountains in the city are gradually integrated with the city.Recently,under the transformation of the relationship between the mountain city,the regional spatial characteristics of the mountain landscape have been diluted,the traditional urban space muscle has been lost due to constructive destruction,the lack of vitality of urban neighborhood characteristics,and the sense of mountain space experience is far from the past.Urban planning and development has changed from incremental planning to stock planning,and urban space has entered the stage of renewal and dual repair.Urban neighborhoods advocate open and small-scale dense road network space form,and the landscape view corridor relationship between mountains and blocks and pedestrian space organizations have also gradually been paid attention to.As the backbone of urban development,neighborhoods and mountains are no longer simple attachments,but more "integrated" relationships.Mountains are also surrounded by urban blocks,becoming a rare "urban bonsai" of the landscape."Building Linshan,Green Mountain into the City,and Integrating Mountain City" is an important spatial architecture mode of Jinan Mountain City.As an important ecological resource in the process of urban development,the human-terrestrial spatial relationship formed by mountains is also an important consideration factor for spatial development.This article takes the 62-seat mountain body within the high speed around the city in Jinan city center as the research object.Starting from the view space of the mountain city from the real perspective of the human-based scale,the natural attributes of the block mountain body are measured by the mountain coverage,discount rate,first rate and general view rate,relying on intelligent wear equipment and mobile phone wide corner setting.Collect the image data of the mountain visual interface of the block.Based on the Axial Map visual axis model,the visual depth of the current block is simulated.Through the visual simulation results,the four types of corridor space,node space,street-on-facing space and open space are determined as future block features.The main control content under mountain guidance.Through the computer visual salience evaluation method,the visual interface of the four types of view areas in the block is quantitatively analyzed,and the significant characteristics of interface space elements,spatial combinations and interface outlines are obtained.Then combine the mountain natural attribute index and block significant attribute index to build a mountain potential classification and evaluation index system in Jinan block,and use Origin Pro analysis software to superimpose and analyze the two types of attributes of each mountain body,and finally divide the 62 block mountains according to the mountain.The significant optimization potential of body interface is divided into nine categories.Combined with the characteristics of different potential types,a significant optimization strategy combining mathematics and aesthetics is proposed,including guiding the open space space of Guanshan in low-optimization potential blocks,combing the interface landscape continuity of medium-optimization potential blocks,and High potential optimizes the overall control of the to-be-built block.Aiming at the differences in the development time series and optimization potential of different blocks,this thesis puts forward the guiding methods of multi-dimensional linkage at the horizontal level,vertical level and the overall level,which provides an exploratory research method and research idea for the quantitative evaluation of the visual spatial interface in urban design,in order to provide a follow-up reality-oriented approach.The quantitative control method of urban design provides a way to learn from.
