苔藓植物在桂北石漠化地区生态修复中的培育
Cultivation of Bryophytes in Ecological Restoration of Rocky Desertification Areas in Northern Guangxi
桂北地区是中国最典型的岩溶地区之一,同时也是石漠化最严重的区域之一,开展石漠化地区生态修复研究具有重要的意义。以桂北地区的桂林市七星区屏风山苔藓实验研究区为研究对象,基于五点取样法筛选桂林屏风山4种典型生境的优势苔藓植物并开展了优势苔藓植物野外培育方法研究,揭示不同坡度处理对苔藓植物的生长变化规律,探索以苔藓植物应用于石漠化地区的生态修复创新方法,为桂北石漠化地区的生态修复提供科学理念和实验依据。遴选了湿地藓、扭口藓和近高山真藓为优势苔藓物种,为石漠化生态修复植物物种作参考。在野外培育试验中,考虑了坡度对苔藓的生长指标的影响,通过分析苔藓植物的覆盖度、株密度、株高度、苔藓结皮层厚度及结皮层干重的试验指标,综合考虑以扭口藓和近高山真藓作为石漠化地区岩面生态恢复的优势苔藓物种,能有效解决桂北石漠化地区大面积基岩裸露问题,提高喀斯特地区的生态效益。
The karst region in Northern Guangxi is one of the most typical and severely rocky desertification areas in China. Research on ecological restoration in this region is of significant importance. The study focused on the moss experimental research area in Pingfeng Mountain, Qixing District, Guilin City. The dominant moss species in four typical habitats were selected using the five-point sampling method. Field cultivation methods for these species were studied. Different slope treatments' effects on moss growth patterns were revealed. Mosses were explored as innovative methods for ecological restoration in rocky desertification areas. Hyophila involuta, Barbula unguiculata, and Bryum paradoxum were identified as dominant species, serving as references for ecological restoration in rocky desertification areas. In the field cultivation experiment, the effects of slope on moss growth indices were considered. The indices analyzed included moss coverage, plant density, plant height, moss crust thickness, and dry weight. Barbula unguiculata and Bryum paradoxum are considered as dominant moss species for ecological restoration of rocky surfaces in desertification areas. They effectively solve the problem of large bare rock surfaces in Northern Guangxi and improve the ecological benefits of karst areas.
