The Study On Urban Thermal Environment In Both Regional Renovation And Urban Planning In Wuhan

Ecological City is a strong sense of the ecology of urban ecosystem, with a reasonable structure, efficient function, and a natural and man-made landscape harmony. The 21st century is the century toward harmony between man and nature. In advancing the process of urbanization, economic development and ecological environment in urban construction has become an inevitable choice. To create fresh air and scenic setting of eco-city is the direction of development and it also can enhance the city's comprehensive strength. And it is the basic standard to measure the effectiveness of urban construction now.This paper concentrates on how to renovate the old region as well as to build new district. Considering the full implementation of the new elements of sustainable development, to protect the natural resources and the creation of a sustainable environment beneficial to the ecological system is the starting point, Such as protection of trees, green parks, lakes and other water resources protection. Through rational planning and environmental analysis,We are aimed to create a suitable living environment while minimizing the damage to the natural environment. Old regions should be not only keep the characteristics of reality but also satisfy the demands of the people,The transformation of urban space can make certain contributions to improve the microclimate . In short, urban planning should be focused on the prospects for development on the basis of existing experience from both at home and abroad to make urban planning reasonable. Therefore, in the promotion of the concept of eco-city, urban space design combining climate and the environment is the only way to improve the environment where we live.Climate in city under the background of regional climate is relatively independent, and the city's development is closely related to human activities, Good urban design is suitable for living and helps to improve the micro-climate in certain region.In this paper, in light of CFD simulation technology to study the climate and environment in the city under the influence of the thermal environment, such as wind conditions, comfort and so on. Combination of weather conditions, establishment of CFD models and the importation of the relevant parameters, and then we can get simulation results. On this basis, talk about the new measures to improve the quality of urban planning and find a new eco-city concept of the fundamental principles of planning. In the transformation of Hanzheng Street, CFD technology is used to choose the suitable programs in light of the actual conditions to improve the climate.This paper studies the impact of climate in urban thermal environment, such as the wind and comfort and puts forward constructive suggestions. At the same time, it can provide effective reference for rational urban design and transformation to improve urban climate and save energy.
