Research On The Optimal Design Strategy Of Outdoor Space In Xi ’an University Campus Based On Microclimate

The outdoor space of a university campus is an important place for teachers and students to exchange activities,carrying various activities and functions of the university campus.Xi’an is a city with a large number of colleges and universities,and its proportion of colleges and universities ranks among the top in the country.Due to the hot and dry summer in Xi’an and the cold and dry weather conditions in winter,teachers and students are unable to spend a long time in the campus outdoor space for long stay and activities,especially colleges and universities that implement fully enclosed management after the epidemic need to strengthen the construction of microclimate-adaptable landscapes.The quality of the campus ecological environment has a close influence on the health of teachers and students.Building a suitable wind,heat and humidity environment in the outdoor space of the campus can provide a place for teachers and students to provide rest,academic exchanges,and entertainment activities,and stimulate the vitality of the campus;on the other hand,it is also conducive to building a green campus and promoting sustainability.Develop and protect the physical and mental health of teachers and students.This article first combs the domestic and foreign microclimate adaptability design research and the development history of campus landscape in colleges and universities found that the microclimate research of campus landscape is still not perfect;secondly,it clarifies the concept of campus landscape microclimate,analyzes related microclimate design cases,and proves that microclimate design is necessary for campus outdoor space design.After that,taking colleges and universities along Chang’an Road in Xi’an as the main research route,the outdoor spaces of the investigated colleges and universities were divided into four types: fully open,semi-open,semi-enclosed,and fully enclosed.After on-site measurement and post-analysis.Later,it was found that semi-open and semienclosed spaces can better meet human comfort requirements than fully open and fullenclosed spaces.When designing a fully open space,it is necessary to consider the problems of improved shading and high heat radiation intensity.This type of space is suitable for entrance landscape areas and cultural and sports activities areas;semi-open spaces are suitable for ecological leisure areas due to the obvious effect of internal wind environment;When designing a semi-enclosed space,it is necessary to improve the dispersion of thermal comfort areas and inconvenience.It is suitable for the design of teaching and research areas and student living areas;the micro-climate environment of the full-enclosed space is poor,and it is recommended to design less fully-enclosed space.It is impossible to avoid this situation.The building spacing can be increased appropriately to add vents to induce air to improve the microclimate.In the end,the representative Yanta campus of Xi’an University of Architecture and Technology was selected as the object of microclimate transformation on the campus,and its problematic outdoor space was measured and simulated by envi-met software.It summarized and proposed the optimized one based on the measured and simulated results.Xijian University’s outdoor space micro-climate adaptability design scheme,and the feasibility of the scheme was verified with the help of software.It is hoped that this article can provide a reference for future research on the outdoor space design of college campuses,and can cause relevant designers to optimize the design of the campus landscape from the perspective of microclimate and ecological sustainability,so as to promote the suitability,ecological,scientific and scientific aspects of landscape design.Parametric perspective development.
