高陡岩质边坡生态修复过程中植物群落与地下生境特征研究
Characters of Vegetation Community and Below-ground Habitats of Ecological Restoration Process on High-steep Slope
摘要
Abstract
In order to explore the characters of vegetation community and below-ground habits of ecological restoration process on different high-steep slope with different technological means,we investigated plant community diversity and below-ground habitats of 5 typical techniques,including slope planting bags,ecological bags,net-suspended spray seeding,planting bags+ net-suspended spray seeding,and lattice+ ecological bags+net-suspended spray seeding.The results showed that 1) the capability to hold water and soil was the core of restoration technology,the thickness of the substrate directly affected the type and condition of the vegetation.2) The trend of plant community evolution was the transformation of the cultivated species to native species or mixed species,the complex modes had the most species with the coverage of up to 90％,so its landscape restoration was the best.While the minimum coverage was net-suspended spray seeding technology,only 10％-30％.3) The major factors influencing species diversity were habitats and repairing ages.Pielou evenness index,Simpson diversity index and Shannon-Wiener diversity index ranked as net-suspended spray seeding＞planting bags and ecological bags＞composite modes,while Patrick richness index and Margalef richness index of composite modes and net-suspended spray seeding technology were higher.Plants community changed mostly during a few initial years after ecological restoration of rocky slope,plant community diversity gradually increased with the repairing period.The study could provide some references for ecological restoration on the high-steep rocky slope in Jinan and even North China.关键词
