Analysis On The Effect Of Different Structural Urban Green To Comfort Degree

The influence of green structure to comfort degree is studied,in greenbelt,beside greenbelt and beyond greenbelt.The influence of green vertical structure,area and shape to green ecological effect is studied individually to find the rule of urban green ecological effect diffusing from bosom to surrounding.The results show that:(1) The comfort degree in urban green is different from bare space. Green vertical structure,area and shape can affect green ecological effect.(2)There are ecological field around urban green.In this area,temperature and humidity will change with the distance to greenbelt.Closer to greenbelt,change stronger.And comfort degree change grads within this area.(3)Urban green can weaken heat island effect. In the degree of heat island weaken,wood > multi-green space > grassland.Area and shape index of green space both correlate to the ability of heat island weaken.The correlations is Linear regression.(4)Roadside green space can reduce temperature and add humidity.The average are 2℃ and 5%.This paper is significant to the quantitative ecological effect study of green space.Meanwhile,it is helpful to urban layout and urban environmental melioration.
