The Construction Investigation And Optimization Strategies Research Of The Typical City Air Path Scenic Spot In Xi’an

As of the end of 2015,China’s resident population urbanization rate has reached 56%.With the rapid progress of urbanization process,urban development space has been expanding outward,occupying farmland,rivers and other green open space.And Highintensity land development and urban construction,not only has undergone great changes of the city underlying surface nature,but also had a negative impact on the city’s windheat environment.City air path scenic spot provides a recreational scene for the community,and has been an important entry point of the urban airway research implementation.The scenic spot can promote the city’s low-altitude atmospheric circulation,ease the city heat island effect,haze weather and air pollution and other climate Environmental problems,improve urban air quality,effectively improve the city’s internal ventilation environment,and form the efficient and smooth "urban respiratory system."First of all,this paper expounds the new concept of "air duct + scenic spot",analyzes the relevant theories and current research status at home and abroad,and analyzes the main features,spatial extent,concrete type and influencing factors of urban wind tunnel scenic area.Secondly,based on the previous study of the scenic spot in Xi’an,this paper analyzes the current situation of the urban ventilation environment and the construction of the air duct system in Xi’an,and analyzes the urban scenic resources in the main urban area of Xi’an,and through the analysis,Screening out the main urban area within the scope of the city in Xi’an area;and from the spatial distribution,resource types of two categories of Xi’an city wind tunnel area resources,and then follow a certain standard to select a number of scenic spots as the paper to carry out the investigation Typical focus.Finally,this paper analyzes the current situation of the ecological environment of Xi’an typical urban airway area and its surrounding environment by fuzzy comprehensive evaluation method,and quantifies the ventilation environment of the urban airway scenic area.On the basis of the the previous study,this paper analyzes the ventilation effect,clears the the main problems of the typical scenic spot scenic,and accordingly cames up with the optimization strategy for scenic spot from the planning,construction and management types.
