Abstract:

To study the micrometeorology characters of different protection modes，five types of representative protection mode on Nanning-Youyiguan expressway,i.e.Type A(Tephrosia candida)，Type B(Melinis minutiflora),Type C(Tephrosia candida+Crotalaria pallida+Semen cajani),Type D(Cement rock slope),Type E(Acacia confusa Merr) were selectet,variation of the micrometeorology of five types of protection mode were observed and compared in 2009～2010.The results showed that the daily average solar radiation intensity was Type D(396.5 W/m2)>Type B(323.1 W/m2)>Type C(163.9 W/m2)>Type A(144.1 W/m2)>Type E(134.2 W/m2).Ddaily average air temperature was Type D(25.5℃)>Type C(25.4℃)>Type B(25.2℃)>Type A(25.0℃)=Type E(25.0℃).Daily average surface temperature was Type D(33.6℃)>Type B(28.4℃)>Type C(26.3℃)>Type A(25.7℃)>Type E(20.3℃).Daily average air temperature was Type C(91%)>Type B(90%)>Type E(89%)>Type A(81%)>Type D(77%).Matrix analysis showed the effect of micrometeorology was Type E>Type A>Type C>Type B>Type D．
