Influence Of The Residential District Layout Of The Shenzhen Riverside On Outdoor Thermal Environment

With a fast speeding urbanization, heat island is becoming a big environment problem in a city’s development, which seriously influences social well beings with an urban context. A contrast of an urban thermal environment decline and a higher living quality requirement is obvious in today’s city development. In order to improve the urban climate, environmental researchers and experts have made plenty studies, where a method in a view of climatic adaptation integrated into urban plan and design is proposed. A river is an important part of the urban ecosystem, which can improve urban thermal environment and increase landscape quality. It is therefore important to investigate the relationship between a residential district layout and the mechanic functions of temperature and humidity of a river. It is considered that a good thermal environment provided by a river can largely improve the outdoor thermal environment of a riverside residential and reduce a heat island.A City riverfront settlement is an important part of Shenzhen in urban ecosystems. The special combination of climatic conditions to optimize the thermal environment as a starting point, simulation analysis using CFD technology riverside settlements thermal environment. Then we can research Shenzhen riverside settlements affecting the relationship of building layout and thermal environment, and summed leverage river microclimate effects of thermal environment riverside settlements building layout optimization strategy.This thesis analyzed climate environment condition of urban river surrounding, found that due to the nature of the river, its air has on its surr ounding of lowering temperature and increasing humidity and wind speed, rivers surrounding climate in good condition. Based on the research of the formation cause of urban heat island, found that city underlaying surface material influence on the intensity of urban heat island effect is larger, the analysis of heat island mitigation methods can be found, reasonable construction planning and design can be in the early stages of the design can reduce the generation of heat island. This study and the riverside residential thermal environment related simulation techniques are studied.By reaching the status of Shenzhen river riverside settlements and conduct research, summing up riverside residential building layout characteristics and studying main building layout nearby the river and river width in Shenzhen, to establish simulation studies of building layout, the base range, river width and other conditions, then simulation study of the layout of the various riverside settlements cases, through the analysis of simulation results, investigate the effect of Shenzhen architectural layout of the outdoor riverside settlements thermal environment, summing leverage river microclimate effects to optimize the thermal environment riverfront building settlements layout strategy. Also discussed strategies in Shenzhen riverside settlements, conduct comparative analysis and simulation optimization for particular settlements, in order to validate the results, and ultimately optimize the urban riverside settlements thermal environment.
