Character and Comparison of Community Stability on Fugou-Xiangcheng Highway Slope
[Objective] 5 typical side slope plant communities that had been revegetated for 8 years on a section of Daguang highway
that is Fugou-Xiangcheng highway (abbreviated as Fuxiang highway)
were selected as research objects. Their stability were measured to provide theoretical foundation for the sustainable landscape construction.[Methods] The data of vegetation community and soil were surveyed and measured. 15 factors of 4 indices involved plant community stability
including species diversity
communities biomass
soil moisture and soil nutrient were used to evaluate the community stability with subordination function method.[Results] Lolium perenne + Trifoliumrepens Linn + Melia azedarach vegetation community had the highest scores of species diversity index
biomass of vegetation communities index and soil moisture index
while the Bidens pilosa + Lolium perenne vegetation community had the highest soil nutrient index. The rank of the 5 typical vegetation communities was Lolium perenne + Trifoliumrepens Linn vegetation community + Melia azedarach vegetation community > Bidens pilosa + Lolium perenne vegetation community > Lolium perenne + Medicago sativa vegetation community > Bidens pilosa + Lolium perenne + Medicago sativa vegetation community > Euonymus fortune vegetation community.[Conclusion] Based on the stability analysis of these vegetation communities
it was concluded that Melia azedarach
Lolium perenne
Trifolium repens and Medicago sativa were the first selected plants for the sustainable landscape in Fuxiang highway. It is better to enrich the vegetation community layers and plant furnishing mode
such as Melia azedarach/Broussonetia papyrifera/Ailanthus altissima/Robinia pseudoacacia + Lolium perenne + Medicago sativa
