Study On Road Traffic Pollution Of Southwestern Mountainous Cities From The Perspective Of Land Use

The southwest region of China covers a vast area,among which are Sichuan,Chongqing,Guizhou,and Yunnan.It is an area where mountainous cities emerge earlier,have more numbers,and have more types of development.The mountainous terrain has all aspects of the development and construction of southwestern mountainous cities.profound impact.In the context of the development of the large-scale western cities,the development of the western region,the transfer of industrial industries in the east,and the gradual return of migrant workers,urban sprawl has accelerated and the urban population has been accelerating.In the context of the state’s development to encourage the development of the auto industry and the people’s lives are increasingly prosperous,The rapid popularity of motor vehicles has become the basis for supporting a large number of human activities and factor exchanges in rapidly expanding cities,and the number and use of motor vehicles have increased dramatically.Road traffic pollution has become an important part of China’s urban environmental pollution,and the impact is increasing.In particular,in the medium-sized mountainous cities in the southwestern region,because of the historical limitations of development concepts and environmental awareness,the original planning and construction did not pay enough attention to road traffic pollution,and there was insufficient understanding of the special impacts of land use on road traffic pollution in southwestern medium-sized mountainous cities.As a result,mountain cities are faced with more pressing road traffic problems than plain cities.The problem of road traffic pollution is even more pronounced,and the human settlement environment of mediumsized mountainous cities in southwest China has further deteriorated.In the context of the new era,the party’s report on the Nineteenth Congress clearly stated that the modernization we are building is a modernization that is in harmony with nature;building an ecological civilization has become a matter of the well-being of people,a national future,and a millenary plan for the sustainable development of the Chinese nation..We are required to fully follow and practice the concept of green development,vigorously advocate the harmonious coexistence between man and nature,and strive to resolve outstanding environmental problems.From the point of view of the status quo of road traffic pollution facing southwestern mountainous cities,the practical needs of sustainable development of mountainous cities in southwestern China,and the requirements of the party and the country for the construction of ecological civilization,the control and optimization of road traffic pollution in southwestern mountainous cities has been It has become an issue that can not be avoided in the planning and construction practice and academic research of southwestern mountainous cities.The source of road traffic pollution is various types of traffic activities in the urban traffic system,and the important root cause of traffic activity is the use of urban land.The generation of various types of traffic activities is closely related to the use of various types of land distributed in cities;road traffic The degree of spread and impact of pollution dissemination is also closely related to the various elements of urban land use,especially the spatial elements.Based on an analysis of urban land use,urban transport systems,and road traffic pollution characteristics and interaction mechanisms,this paper analyzes the urban land use characteristics and road traffic pollution characteristics of medium-sized mountainous cities in the southwest region,and selects them for more general representation.Sexual Zigong City conducted a corresponding analysis to sort out the relationships between various elements of land use in mountainous cities and road traffic pollution from multiple levels,and constructed a road traffic pollution control optimization system for southwestern medium-sized mountainous cities from the perspective of land use.The control optimization and sustainable development of road traffic pollution in medium-sized mountainous cities put forward corresponding countermeasures.The paper is divided into six chapters.Chapter One Introduction.The background,purpose and significance of the study,and the content of the study are described.The related concepts of Southwest China,mountain cities,road traffic pollution,and urban land use are explained and explained.In order to determine the feasibility of this research idea,we have organized and summarized domestic and international studies on urban land use,urban transport systems,and road traffic pollution through the review of related research at home and abroad,and proposed the framework of this study.The second chapter studies the characteristics and interaction mechanism of urban land use,urban transport system,road traffic pollution.Based on the summarization of related studies at home and abroad,relevant theories and case studies,this paper focuses on the two major direct research objects of urban land use and road traffic pollution,and the urban road traffic system closely related to both.Analyze the three levels of view and micro-level,and decompose various elements of the three,and discuss the mechanism of each factor’s impact on road traffic pollution from the three stages of the generation,transmission and impact of road traffic pollution.This paper provides the basis for the system construction and optimization strategy for the prevention and control of road traffic pollution in southwestern mountainous cities from the perspective of urban land use.The third chapter is the development of the middle-sized mountainous cities in southwest China and their characteristics of land use.Based on the theoretical support of the characteristics of urban land use,urban transport system and road traffic conditions and the interaction mechanism among them,through the collection of data and field research on land use,the development level of urban development in the middle-andmiddle mountainous cities in the southwest The characteristics of population distribution,urban development,and overall characteristics of land use were analyzed.Land use was characterized from the aspects of land use morphological characteristics,expansion characteristics,third-line construction characteristics,differentiation characteristics of new and old urban areas,and functional index characteristics.The fourth chapter is about the characteristics of road traffic pollution in middlesized mountainous cities in southwestern China and their conflicts with urban land use.Through the collection of data on the pollution of middle-size mountainous cities in the southwest and on-the-spot investigations,the overall state of atmospheric pollution in middle-sized mountainous cities in southwest China was determined,and the road traffic exhaust fumes,dust pollution,and road traffic noise pollution in middle-and-southern mountainous cities in southwestern China were studied.,pollution contribution,spatial and temporal characteristics,etc.On this basis,the representative representative city of Zigong is selected for further research.The impact relationship between urban land use and road traffic pollution is explored without a level,and the generation and spread of road traffic pollution in urban southwestern middle-level cities is discussed together with urban land.Contradictions between uses.The fifth chapter is the construction and intervening strategy of road traffic pollution control system in southwestern medium-sized mountainous city from the perspective of urban land use.On the basis of theoretical summarization and empirical research above,we will construct a road traffic pollution control system for medium-sized and mediumsized southwestern cities under the perspective of urban land use.On this basis,we will combine urban planning systems at all levels and guide the overall policy.The overall planning of the city’s overall planning,the introduction of meso-and micro-level urban design and controlled detailed planning control multiple levels,the control of the various elements of the control system,to intervene in the characteristics of land use as a means to control the optimization of road traffic pollution For the goal,put forward optimization countermeasures from different planning levels.Chapter VI,Conclusions and Prospects.The main contents and conclusions of this paper are summarized and analyzed.The omissions and shortcomings in this study are analyzed.In light of the omissions and shortcomings,combined with the development of new technologies and new methods,we look forward to the future of further research.
