Study On Shading Parking Lot

The uncovered parking will be hot heat point source as land surface temperature is high in summer which can hence heat island effect.At the same time,the temperature is too high to drive the car.As shade parking lot can solve those negative problems,therefore,the construction of the shade parking lot has become a trend.The paper test temperature,humidity,light intensities,UV-B,land surface temperature which is about different arbor species,different tree crown cover?different parking space design patterns.The result shows that the every indicator of Platanus occidentalis Fraxinus pennsylvanica Ailanthus altissima is higher then other arbor species significantly;the every indicator of “two parking space is neighbor which is interved green ”is higher then the every indicator of “three parking space is neighbor which is interved green ”.The paper built shading parking lot evaluation model which include 12 indicators that based on the relative researches and construction status of Beijing,which according to balance 3 sides function,such as secological function,landscape function,economic function.The indexes are analyzed quantitatively and qualitatively,mainly quantitatively.The analysis comprehensively covers all aspects of shading parking lot.After comparing multi available evaluationmethods,the AHP Methods are selected to calculate the weight of eachlevel evaluation index of the shading parking lot.After data statistical ranking and comparative analysis,the importance of each index in the evaluation factor is definite.On the basis of the determination of the ecological functions,evaluating different species,different parking arrangement and other aspects.Choosing Platanus occidentalis.Fraxinus pennsylvanica.Ailanthus altissima as the suitable arbor as the combined effect is good;Choosing “two parking space is neighbor which is interved green ” as better parking space design patterns.According to take three typical parking lots of beijing as example aim to evaluate and design parking lots.Expecting that can provide guidance to shade parking lot construction.
