摘要
采用混凝土喷护坡面苔藓调查以及苔藓植生技术室内与现场实验等手段,开展了生态基层水泥含量对苔藓生长影响研究,研制了抗雨水冲刷苔藓植生基层,提出了基于苔藓植生技术的混凝土喷护坡面生态重建新技术。研究结果表明:(1)黄砂藓和细叶真藓可以作为重庆地区混凝土喷护坡面生态重建耐旱苔藓藓种。苔藓作为混凝土喷护坡面生态重建的先锋植物,可为后期伴生草本植物的生长创造生境。(2)采用河沙和菜园土作为苔藓植生基层主要基质、水泥质量占比为10%~20%时,既能满足苔藓植生基层抵抗雨水冲刷的要求又能满足苔藓生长的需要。(3)苔藓作为混凝土喷护面生态重建的先锋植物,可为后期伴生草木植物的生长创造微生境,从而达到提高生物多样性目的。研究结果可为混凝土边坡的生态修复提供技术参考和实践经验。
Based on the bryophyte investigation,indoor test and field experiments on the concrete sprayed slope,the influence of cement content in ecological substratum on bryophyte growth was studied.A bryophyte ecological substratum resistant to rain erosion was developed,and an ecological reconstruction technique for sprayed concrete slop based on bryophyte planting technology was proposed.The results shows that:(1)Racomitrium anomodontoides and Bryum capillare are two dominant bryophytes on concrete sprayed slopes in Chongqing area,and can be applied for ecological reconstruction;(2)When the cement content is 10%~20%in moss ecological substratum mainly consisting of river sand and vegetable soil,the substratum can resist rain erosion and is suitable for drought-resistant bryophyte growth;(3)Bryophyte is the pioneer plant in the ecological reconstruction of sprayed concrete slope and can create a microhabitat for herbaceous plants to enhance biodiversity.The research results can provide technical reference and practical experience for the ecological reconstruction of concrete slopes.
