| 摘 要： | 目的]以生长8a的大广高速公路扶沟—项城段边坡植被(简称扶项高速)为研究对象,选择5种典型植物群落,进行群落稳定性测度,为营建高速公路可持续景观提供理论依据。方法]通过实地调研获得植物群落和土壤数据,提取对植物群落稳定性影响较大的群落物种多样性、群落生物量、土壤水分、土壤养分4项指标共计15个评价因子,通过隶属函数法对其进行稳定性测度。结果]黑麦草+白三叶+楝树群落的物种多样性指标、生物量指标和土壤水分指标最高,土壤养分指标最高的是鬼针草+黑麦草群落。5种植物群落稳定性排序为:黑麦草+白三叶+楝树群落鬼针草+黑麦草群落黑麦草+紫花苜蓿群落鬼针草+黑麦草+艾草群落小叶扶芳藤群落。结论]通过对植物群落稳定性分析,得出楝树、黑麦草、白三叶、紫花苜蓿为扶项高速公路边坡可持续景观营建的首选植物,在植物配置时应丰富群落层次,推荐配置模式楝树/构树/椿树/刺槐+黑麦草+紫花苜蓿;楝树/构树/椿树/刺槐+紫穗槐+白三叶+黑麦草;楝树/构树/椿树/刺槐+紫穗槐+紫花苜蓿+黑麦草。

| Abstract: | 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, Melia azedarach/Broussonetia papyrifera/Ailanthus altissima/Robinia pseudoacacia + Amorpha fruticosa + Trifolium repens + Lolium perenne, Melia azedarach/Broussonetia papyrifera/Ailanthus altissima/Robinia pseudoacacia + Amorpha fruticosa + Medicago sativa + Lolium perenne. |
