| At present,with the acceleration of the urbanization process,a large number of construction activities have impacted the traditional ancient towns in the southwest,and their historical relics with important values are facing real threats,and their local characteristics are slowly being eroded.As a special landscape type and heritage composition,geological landscape is the product of natural geological evolution and human activities.It widely exists in the settlement space of ancient towns,and has begun to attract the attention of relevant research scholars,experts,media,and governments.Therefore,re-examining the material composition and value connotation of the ancient towns in the southwest from the perspective of geological landscape is objectively necessary.It aims to face up to the objective material entities that reflect the relationship between man and nature in the process of historical evolution,and to promote the interdisciplinary and comprehensive study of the protection of the ancient towns in the southwest And system construction.Therefore,this paper draws on the theories of geology,urban and rural planning,history,landscape geography and other related research results,and conducts specific research based on the idea of "proposing questions one by one and analyzing them one by one" :First,the research progress of the geological landscape and the ancient towns in the southwest is sorted out,and scientific research questions are raised.On the one hand,it systematically sorts out the types of geological landscapes,their material composition,and value connotations,and makes a comprehensive review of relevant research progress at home and abroad.There is not enough research in scale area to pay attention.On the other hand,a comprehensive review of the existing research theories and protection practice results of the ancient southwestern towns is proposed,focusing on the protection of cultural heritage,and insufficient research on the geological composition in the natural environment.Based on this,combined with the current research insufficiency and crossdisciplinary research ideas,this paper focuses on the research entry point and research object of this article-the geological landscape of the ancient southwestern town.Second,analyze the geological landscape of the southwest ancient town.On the one hand,by combing the background of natural geography,regional geology,and social and humanities of the ancient southwestern town,it was found that the geological landscape is a landscape phenomenon formed around geology and human activities,which reflects the human-land relationship of the ancient southwestern town and contains the regional characteristics,Diversity and inheritance,with a certain functional shift and cultural transmission.Based on this,combined with the morphological characteristics of the landscape,it is divided into three major categories: natural,settlement and cultural.Seven sub-categories and several landscapes are specific,which is convenient for later landscape classification research.On the other hand,combined with the study of the relationship between landscape entities and space carriers,the material basis correlation,historical fact correlation and spatial distribution correlation are proposed from the spatial and temporal scales.Third,note that it is different from the traditional way of landscape formation.The geological landscape of the southwest ancient town is developed and evolved under a complex and dynamic background,which reflects the adaptive transformation and cultural nature of the specific environment under the interactive game of human and nature.Blend and form a new organic whole.From the perspective of the geological landscape entity,the southwest ancient town is taken as the carrier of its development and evolution,and it is regarded as a complete historical process.It is analyzed and summarized its evolution law from three aspects: evolution stage,evolution main line,and evolution motivation.The research shows that:（1）the evolution stage: specifically includes the nascent stage,the development stage,the flourishing stage,and the decline stage;（2）the evolution main line: specifically includes the evolution of geological environment,the evolution of settlement construction,the evolution of regional culture,and the evolution of politics and military,of which the first two The latter is the common main line and has a high degree of dominance over the formation and development of the landscape.The latter two are characteristic main lines that deeply depict the highlights of historical accumulation and regional characteristics in the process of landscape development.（3）Evolutionary factors: the geological environment Support is the endogenous driving force,driven by the spiral of comprehensive and complex humanland relations as the core drive,the continuous penetration of multicultural integration as the continuous guarantee,and the change of special situations as the stage of intervention.Based on this,we have a comprehensive understanding of the geological landscape of the ancient southwestern town,and understand the path organization and internal laws of the coordinated evolution of human and land,so as to provide a basis for the protection path construction below.Finally,taking the ancient town of Zhongshan as a typical case,the construction of the protection path of the geological landscape is discussed.On the basis of the previous landscape analysis and historical evolution.According to the previous classification,landscape classification is carried out,and comprehensive value research and judgment are carried out through the degree of landscape scarcity,value connotation,evolution law,and existing problems.Based on this,the exploration of protection path construction is carried out based on the idea of "priority protection and moderate development",and specific strategies are proposed from the four dimensions of cognitive enhancement,landscape governance,industrial guidance,and policy support.Finally,the research conclusions of the full text are summarized,the innovation points and deficiencies of the thesis are put forward,and future research trends are expected to provide certain directions and guidance for future research. |
