摘要:

苔藓植物参与岩溶作用的过程是生物岩溶的重要内容。开展苔藓植物岩溶作用研究可为石漠化裸岩的生态恢复及其综合治理提供理论依据和技术支撑。该文系统论述了苔藓植物岩溶作用的过程(溶蚀与沉积)、机理及其与生境互作机制的最新研究进展。苔藓植物及其生物结皮在干湿交替下发生膨胀、卷缩、冻融等物理机械力, 以及其代谢分泌物和因呼吸作用而产生的H2CO3与岩石中矿物反应, 破坏矿物晶体结构, 导致矿物裂解、使岩面崩解脱落而改变岩面形态, 塑造岩溶地貌, 形成原始土壤。苔藓植物岩溶作用驱动力的大小与植物功能性状、基岩性质与生存环境密切相关。此外, 生物岩溶作用需要长时间尺度的监测, 研究周期长, 建议建立野外长期监测基地, 加强对其内在机制与过程以及与生境间互作机制, 苔藓植物的生理代谢过程及其生物酶等与岩溶作用的相互关系, 岩溶地区苔藓植物环境适应性特征及其生物多样性维持机制等方面的研究。

Abstract:
Bryophyte participate in karstification is an important part of biokarst process. Numerous studies on bryophyte karstification provide theoretical and technical foundation for restoration and comprehensive management of bare rock in the rocky desertification area. This article systematically reviewed the process (dissolution and sedimentation), mechanism and interaction relationship between bryophyte karstification and habitats. Bryophyte and its biological crusts emerge physical forces such as expansion, curling, freezing and thawing when they are under alternating wet or dry conditions can destroy rock. In addition, their metabolic secretions and H2CO3 formed by respiration, which react with minerals resulting in destruction of the crystal structure, pyrolysis the minerals, further the rock surface disintegrated and the surface morphology changed, the karst landform and the original soil formed. The driving force of bryophyte karstification closely related to plant functional traits, rock properties and habitat. Studies on biokarst need long-term monitoring and long research period. It is recommended to establish a long-term monitoring sites for strengthening examinations on process, internal mechanisms, and interaction relationship with habitat of bryophyte karstification. At the same time, physiological metabolic processes of bryophytes and the relationship with bryophyte karstification should be emphasized. The environmental adaptability of bryophyte and the maintenance mechanism of biodiversity in karst areas need research attention as well.
