- 摘要:
- 为了探明高速公路边坡不同防护模式的小气候特征,于2009~2010年,在南宁至友谊关高速公路边坡上选择代表性的护坡模式设置固定样地,开展主要气象要素的同步对比观测。结果表明:日平均太阳辐照度显示出水泥岩石模式(396.5 W/m2)>糖蜜草模式(323.1 W/m2)>三豆混交模式(163.9 W/m2)>山毛豆模式(144.1 W/m2)>台湾相思模式(134.2 W/m2)。日平均气温显示出水泥岩石模式(25.5℃)>三豆混交模式(25.4℃)>糖蜜草模式(25.2℃)>山毛豆模式及台湾相思模式(25.0℃)。地表温度显示出水泥岩石模式(33.6℃)>糖蜜草模式(28.4℃)>三豆混交模式(26.3℃)>山毛豆模式(25.7℃)>台湾相思模式(20.3℃)。日平均空气相对湿度显示出三豆混交模式(91%)>糖蜜草模式(90%)>台湾相思模式(89%)>山毛豆模式(81%)>水泥岩石模式(77%)。矩阵分析得出,5种防护模式对小气候调节作用的总排序为台湾相思模式>山毛豆模式>三豆混交模式>糖蜜草模式>水泥岩石模式。
- 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.
