Research On The Placeness Evaluation And Optimization Strategy Of Landscape Lighting In Historical And Cultural Blocks

Historical and cultural blocks are one of the important heritages in the process of urban evolution and development.With the continuous development of the idea of "night tour economy",the night view of historical and cultural blocks has become the focus of urban development.Nightscape lighting,as an important means of street plasticity,has some phenomena,such as not obvious street characteristics,lack of overall coordination of lighting,contradiction between lighting and protection needs,neglect of tourists’ visual feelings and so on,Failing to give full play to the connotation and spirit of historical and cultural blockts,which leads to the lack of placeness,has finally reduced many neighborhoods with precious historical value to commercial streets lacking urban characteristics.Therefore,how to base on the regional cultural connotation,balance the interests of all parties and reshape the place of historical and cultural districts is an important issue in the development of urban nightscape lighting.Firstly,this thesis selects representative residential,cultural and commercial historical and cultural blocks through field research,analyzes the current situation of street nightscape lighting and summed up the issues.Secondly,by summing up existing studies ideas,consulting specialists,combining nighttime lighting status in historical and cultural blocks,the evaluation indicators of nightscape lighting in historical and cultural blocks are collected from the perspective of regional culture,and the evaluation indicators are selected through questionnaire analysis,so as to construct the evaluation indicator system of nightscape lighting in historical and cultural blocks.There are five potential variables,including identifiability,reachability,vitality,context and comfort,and 29 observational targets were established.Then,based on the index system and the structural equation model as the main research method,the establishment of the historical cultural district nightview lighting site evaluation data model.After sorting out the survey data collected by three types of historical and cultural blocks,input the model to obtain the influence weights of potential variables and observed indicators,and analyze the size and causes of weight values.In conclusion,based on the results of the data analysis and the current situation of night lighting in historical and cultural blocks,the principles,implementation path,overall optimization strategy and targeted optimization strategy of the historical and cultural street nightscape lighting in the south of Hebei Province are proposed,so as to improve the location of street nightscape lighting.The innovation points of this thesis are mainly embodies in the next three aspects: one is the construction of nightscape lighting evaluation index system.place of historical and cultural districts from the perspective of regional culture;Second,the establishment of the historical and cultural districts in the southern Hebei Province nightview lighting site evaluation data model;Third,put forward the overall and targeted optimization strategy of nightscape lighting in historical and cultural blocks.By combining qualitative and quantitative methods,the evaluation system is established,the evaluation data model is constructed,and the optimization strategy is put forward,so as to realize the purpose of exploring the place character of nightscape lighting in historical and cultural blocks from the perspective of regional culture.In order to provide reference and guidance for the research on the place character of the nightscape lighting in the city’s historical and cultural blocks,the corresponding optimization strategy is proposed for the shaping of the place character of the historical and cultural blocks.
