四川盆地岩石边坡适应性植物选择

Selection for Adaptive Plants to the Rock Slope in Sichuan Basin

根据四川盆地的自然气候条件及岩石边坡立地条件,以抗逆性(抗旱性、抗病虫害等)、品质特性(出苗率、覆盖度等)、功能效益(涵固土性、景观效果等)为筛选准则,运用层次分析法,综合评价并选择出适合于四川盆地岩石边坡立地条件生长的适应性植物。结果表明:在参试的24种植物中,银合欢、紫穗槐、黄荆、多花木蓝、截叶胡枝子等9种适应于四川盆地岩石边坡立地条件的恢复植物,它们具有抗逆性强、护坡效果好、造价相对低廉等特点,可应用于植被恢复实践。

In order to select suitable plants that can be used for the rock slope in Sichuan Basin, an assessment system were established, which consisted of plants resistance （drought resistance, diseases resistance, etc. ）, quality （emergence rate, coverage,etc. ） and function（soil fixing, visual effect, etc. ）. The AHP approaches were used, which stands for analytic hierarchy process ,combined with experiment, to assess the adaptability of 24 suitable plants from the data of experiment. The results showed that in 24 species tested, 9 suitable species were selected,such as Leucaena leucocephala ,Arnorpha fruticosa ,Witex negundo, Indigofera amblyantha ,Lespedeza cuneata, etc. for the restoration on rock slope in Sichuan Basin. These adaptive plants were resistant to stress,effective to revetment,and relatively inexpensive.
