RESEARCH ON THE PLANNING METHOD OF SHARED SPACE IN OLD RESIDENTIAL DISTRICT BASED ON THE IMPROVEMENT OF ECOLOGICAL ENVIRONMIENT

摘要

In order to improve the comfort and functions of the old living shared space environment, and en-hance the suitability of the shared space ecological environment, in this paper, an old living area shared space planning method based on the improvement of the ecological environment is proposed. The ENVI-met model combined with one-dimensional and three-dimensional algorithms was established, and the microclimate environment was simulated through the calculation of the thermal stress relation-ship between vegetation and air. In addition, the shared space in the old residential area is planned from four aspects: architectural layout, activity ven-ues,landscape greening and road organization. Ac-cording to the simulation results of ENVI-met, the layout of the building and the location of the event venue were planned by "bearing the shade and em-bracing the sun" and side by side/staggered layout. In the end, road grades and transportation methods combined with plant morphological characteristics were used to complete road organization and land-scape greening planning. The experimental results show that the shared space planned by this method can ensure the best environmental suitability and sunshine effect.After planning, its temperature drops by an average of about 1.2°CC, which can improve the comfort of the human body in the shared space.
