The Parking Lot Configuration Of Tree Species Selection And Energy-saving Effect Analysis

The parking lot is one of the types of urban green space,Selection and configuration of parking lot tree species, both with the use function of the space, and the space of green ecological city planning and construction related. This paper takes Suzhou city parking lot tree application basis, takes Suzhou city greening tree species commonly used Joe temperature, light transmittance as the starting point, Select suitable tree species for Suzhou city parking lot. Test car under the sun, camphor, acacia, the temperature and humidity changes, Calculation and analysis of the influence of different tree species for carriage temperature heat effect. And provides open-air parking lot allocation scheme of vertical and inclined type two types, Analysis thermal effect of them. The main results of this research are listed as follows:(1) This paper choose 15 species of Suzhou urban greening commonly used big trees,test tree shade space and sunshine space temperature difference value in the summer and winter. Determine the Maple, Magnolia, Acacia, Chinese Tallow four tree species as Parking space tree species. These 4 kinds of trees have both evergreen and deciduous trees, In addition to meet the requirement of summer cooling and winter warming, they are better ornamental and seasonal variation more than Camphor.(2) The specific number of different trees saving gasoline(No. 93) in the summer and winter annual can be listed as follows: Camphor51.25(ml)、Maple 62.45(ml)、magnolia46.85(ml)、Chinese Tallow68.7(ml)、Acacia26.7(ml). Among them, the energy-saving effect of tallow and Chinese beech is better than camphor, increase of 34.05% and 21.85% respectively. So Chinese beech and tallow can better meet the functional requirements of ecological parking field, can be used as main tree species of parking lot. The energy saving effect of Magnolia and Acacia is lower than camphor, reduced by 8.59% and 47.90% respectively. But these species has more ornamental characteristics of the landscape, can be used as secondary tree species of parking lot.(3) Vertical type parking lot with 100 parking Spaces, If using camphor as greening tree species, A year of winter and summer can save about 3.04 L of gasoline(No. 93); But choose four tree species selected by this paper, A year of winter and summer can save about 3.50 L of gasoline(No. 93); The selection of tree species in this paper can save more fuel than Camphor, save 0.46 L gasoline(No. 93).Inclined column type parking lot with 100 parking space, If using camphor as greening tree species, A year of winter and summer can save about.94 L of gasoline(No. 93); But choose four tree species selected by this paper, A year of winter and summer can save about 3.21 L of gasoline(No. 93); The selection of tree species in this paper can save more fuel than Camphor, save 0.28 L gasoline(No. 93).(4) The private car ownership is more than 2 million vehicles(2013) in Suzhou, In this paper, we take 2 million as reference to evaluate car ownership. Assuming that these vehicles in daily use process need to use urban outdoor parking lot, if you use the parking space tree configuration scheme are studied in this paper, it will play an important role in the construction of ecological city of Suzhou in theory.In theory, Camphor tree planting vertical parking lot, compared with the direct sunlight parking lot, Annual summer and winter can save gasoline(No.93)60800(L); This paper choose the tree shade configuration vertical parking lot, compared with the direct sunlight in the parking lot, annual summer can save gasoline(93) 70000(L); Compared with the Camphor tree planting parking lot, annual summer can save gasoline(93) 9200(L).In theory, Camphor tree planting inclined column type parking lot, compared with the direct sunlight parking lot, Annual summer and winter can save gasoline(No.93) 58800(L); This paper choose the tree shade configuration vertical parking lot, compared with the direct sunlight in the parking lot, annual summer can save gasoline(93) 64200(L); Compared with the Camphor tree planting parking lot, annual summer can save gasoline(93) 5400(L).
