The Study Of "Shade Of Forest Effect" For Open-Spaces In Urban Environment

The urban environment open-spaces, like the city streets, the squares, the parks and so on, are must outdoors spaces for people to go to social contact and the leisure activity, but at present outdoor hot environment of these city open space should have a improvement.The afforestation have a vital role in improving outdoor hot environment quality and enhance the human body comfort level, especially the trees have the extremely good performance in this aspect. The function of shading of trees and control action in the humiture, which has promoted the human body comfort in the outdoors environment, has the advantageous influence to the human body health too, also may produce good cherishes the people the effect. however, at present, the urban environment open space afforestation design often many excessively emphasized the visual landscape, the esthetic consciousness or pursues its ecology benefit excessively, thus has caused the following phenomenon:the green space function not to be imperfect, the deficient of usefulless and affinity of the public active space.Not only the trees have obviously function in shading and decreasing the temperature, but also has the very big display leeway in designing amusement and rest activity space.This article proposed the shade of forest space, is one kind of display trees provides shade the function and provides the open-type plant space which the amusement and rest activity has both. First proved the shade of forest space through the literature research method to provide shade the function and the temperature decrease humidification effect, next to the Xi'an partial urban environment opening space (city street, square and park) the shade of forest space case launched the investigation, the discussion analyzes the shade of forest space the overall appearance and cherishes the people the effect, after but unified own practice case to carry on the analysis to summarize, has induced the Xi'an city opening space common shade of forest tree seed's type and provides shade the effect, the shade of forest space design application proposed to the present city opening space in some suggestions, finally summarized the shade of forest space construction tree seed's choice standard, analyzed the shade of forest space to cherish the people the effect, simultaneously proposed each different typeln open spatial shade of forest space design guiding principle.Above discussion, the regulations are to the city opening space afforestation design one kind of brand-new ponder, how namely establishes open plant spaces in the city opening space, which have these traits,such the amusement and rest function, dreasing the temperature. The establish of this plant space will can improve ecological environment, promote human body comfort, and can provide the effective active space for the tourist.Expected that this article can provide some useful materials and the reference value for later planting design in city open space.
