The Improving Strategies On Wind Environment Of Rural Countyard In The Northeast Cold Regions

With the development of the northeast cold region village construction in China, rural residents living standards improve, and the living environment is also growing. Because of the way of life in rural area exists obvious difference compared with urban residents, according to research statistics about 75% of the project was conducted in the outdoor activity, the main activities include farming, household chores, leisure, etc., and the main places are their yards. So the physical environment quality will directly affect the production efficiency and the quality of residents’ life. Through the visiting research in cold region of rural, the demand of rural residents to improve the physical environment of outdoor is very big, with 78.3% of the respondents think courtyard wind environment has a n impact on their outdoor activities directly. So improving wind environment is one of the important ways to improving rural residents’ quality of life.The rural courtyard wind environment in severe cold region is the research object. First of all, based on the questionnaire investigation and analysis of 33 villages from Hei Longjiang, Ji Lin, Liao Ning and Inner Mongolia provinces, summed up the yard elements of villages and towns, and the outdoor activities of residents around these elements, carried out the activity type s and regions as the basis of simulation optimization. Second, selected the three typical courtyard for field testing, through the analysis of the objective data, from the macroscopic and microscopic two aspects respectively analyzed the courtyard wind environment characteristics and impact factors, and verified the Fluent software to simulate fluid analysis software in rural courtyard wind environment of the effectiveness and applicability. Finally, the simulation software is adopted to simulat e and analyse the four kinds of classification of courtyard patterns according to the courtyard shapes, the building envelopes, the building locations, the wall styles. It is concluded thatthe wind environment characteristics under different conditions, and then put forward the wind environment design strategies from layout forms, height and wall material, green plants configuration and other aspects of rural courtyard in northeast cold region.This article adopts the means of software simulation to simulate the simplified model of typical rural courtyard in the northeast cold region China, and combining with the characteristics of the activities of the local residents and the wind environmental problems existing in the present situation, from the aspect s of building design the strategies are put forward, aiming at improving the northeast cold region rural courtyard wind environment and providing the design basis and methods.
