Abstract:
Urban green land especially woody plants within it played an important role in regulating air temperature and improving living conditions.Taking four kinds of amenity forest in Dongguan as research object，the light transmittance and shading effect using hemispherical photography were analyzed and estimated.The results showed that there were 19 families，33 genera and 37 species of trees in total in the four study sites，Renmin park had the most abundance species and its shading effect was the best；canopy openness (CO)，the transmittance of transmitted diffused light and total light had a significance difference in the four urban green lands (P<0.01) except transmitted direct light，besides，the transmittance of transmitted light had a significance linear correlation with CO (P<0.01) which indicated that good canopy structure could reduce transmittance and enhance radiation attenuation effect.The four amenity forests had a good shading effect.
