Study On Optimization Of Micro-climate Environment Of Urban Greenways In Northern China

In recent years,with the changes of cites and the progress of the times,a lot of outsiders flocked to the city center,which led to a continuous increase in population,the growing pressure of urban life and the city continued to expand outward.In this case,the environment has been destroyed.The rapid development of urbanization makes the population more and more intensive,so that people are increasingly difficult to "breathe".Many people want to escape from this environment,find a place to let themselves relax and have a comfortable rest.Then a new term the greenway appears.Greenways can not only inlaid country and water,but also connect the broken city spaces together,offering people a comfortable and relaxing environment.In the rapid development of the city,many city public spaces,having a historical and cultural background,disappeared in the era of migration.These cultural monuments are the spiritual wealth that we modern people pursuit.Every city has its unique character and the historical trace is the soul of the city,which plays an important role in promoting development of urban renewal and improving people's quality.The emergence of urban greenways,as a new form of expression,can not only retain the history and culture,but also update the design on the basis of reservation.As a conservation corridor for the natural and cultural heritage,the city greenway,consisting of pedestrian trails and bike paths,offers a wide range of recreational spaces for the public,and appears in people's life as a kind of human development of the natural corridor.In general,the indoor environment is a small environment for people's daily life.This kind of small climate in particular environment was called the micro-climate.As the environmental issues we concerned,the new term micro-climate began to highlight itsimportance,and to a large extent determine the quality of life.To provide a more livable landscape environment,many cities are trying to combine urban greenway and micro-climate with each other.To improve people's quality of life,this paper mainly studies how to create a good micro-climate environment in the greenway,which is a linear space.Nowadays,people advocate sustainable development.In this condition,improving people's comfort and the environmental pollution caused by the outside world can optimize the environment and climate and provide a strong help for the city's development.We need to study the impact of different microclimatic factors on the environment,then summed up a set of applicable theoretical methods to optimize the micro-climate environment and help people find a more suitable micro-environment for living.The paper analyzed the significance of the microclimatic environment and the methods adopted in the domestic and international greenway cases.By conducting a few field visits to Beijing greenways and distributing the questionnaire and doing some data measurement,the paper analyzed in which circumstances the greenway,under the effect of the microclimatic factors,is most suitable for leisure.Beijing greenway was chosen as the research object.After summarizing the theory of the relevant literature,analyzing the data of the field,studying the change law of the urban greenway and the micro-climate factor,the paper summarized when climate was most optimized.The research mainly deals with the control method of climate contradiction in landscape design and puts forward the reference and practice method of outdoor leisure which satisfies people's comfort.
