| The overlapping utilization of mountainous urban space has produced multi-level and multi-functional coexisting spaces,leading to the phenomenon in which urban and architectural penetrate each other and multiple functional spaces coexist.Therefore,the systemity of urban space has also been enhanced.Taking Chongqing as an example,the unique topographical makes the city separate from upper and lower cities.To solve the traffic connection between them,the cities have derived various forms of transportation and produced system spaces in the upper and lower cities.How to reduce the obstacles of pathfinding,improve imaginable planning and design method of the three-dimensional walking system in mountainous cities have become important issues.This research is based on spatial cognition.Research object is mountainous threedimensional walking system,the content is “imageability”,and the method is mainly“pathfinding”.(1)Research starts from popular social phenomena.By researching the phenomenon of “spatial loss” in Chongqing through network measurement,macro quantitative model(SEM)map,the foundation for subsequent research can be layed.(2)Next,to design imageable cognitive experiments based on the cognitive theory at the micro level.The experiment uses methods such as observation,behavioral annotation,online questionnaires,and interviews to study the way-finding behavior of the crowd.From people’s perception,the purpose is to search the factors of imageability.(3)Analyzing the influencing factors and mechanism of imageability through SEM.(4)Hopefully,spatial loss graph gradually shifted from a single-view,macroscopic,and mechanical model to a multi-view,clear,and flexible imageability graph model.By analyzing the path of graph model,corresponding space strategies can be put forward after researching imageability.Finally,the purpose is to practice imageable plans and design methods combined with examples.The 1st and 2nd chapters are related background,concept proposal,related theoretical research and a summary of related theories.The 3rd and 4th chapters take the Yuzhong Peninsula and Lianglukou three-dimensional walking system as the research object from the macro and micro perspectives.Methods such as network measurement,questionnaires,interviews,and spatial experiments are used to find out the dimensions and related factors of imageability.Furthermore,to construct a graph model of imageability.The 5th chapter is the conclusion and practical strategies.According to the graph model obtained by the research,the graph model is analyzed and spatial strategy is proposed.The 6th chapter is the narrative summary of the subsequent extension attempts and research.The conclusions are:(1)Through a macro investigation of the dimensions of spatial loss which is defined by five dimensions: built environment,environmental constraints,historical and cultural background and spatial activities.(2)The research has gradually deepened from “spatial loss” to “imageability”.The research on the disorientation provides a site and establishes the prototype of methodology for follow-up research.Finally,Lianglukou three-dimensional walking system is chosen for further research site.(3)Through investigation of Lianglukou area,the author found out influence dimensions and constituent factors of imageability.After further evaluation and revision,the researcher re-summarized 11 dimensions and 84 factors that are obviously related to imageability.(4)Using SEM to verify selected dimensions and factors,7-8 dimensions and 21 factors that are significantly related to imageability are found.They are reclassified into 3 dimensions:(1)Spatial identifiability.(2)Regional,historical and cultural characteristics.(3)Public activities.(5)Through specific problems,measures are put forward to.Finally,it is hoped that Linglukou three-dimensional pedestrian system can evolve and grow simultaneously along with cognitive results in the future. |
