    摘要:

    [目的] 系统梳理、总结、分析岩石-土壤-植物三者间协同作用的研究现状,重点探讨植物在石质化土壤环境下的适应机制,以期为石质生境植被生长及生态环境修复提供理论支撑和科学依据。[方法] 从内因岩石碎片含量及埋深、外因植被类型及降雨气候条件等不同维度,深入分析石质土壤对植物生长的综合效应,揭示石质化生境下植物在形态、生理及分子层面的适应策略。[结果] 石质土壤对植物生长的调控作用与岩石形状、含量、埋深以及气候条件、植物类型等因素密切相关。石质土壤中的植物受限因素主要是土壤水分和养分匮乏。在此情形下,植物会通过调节自身生长性状及生理代谢以更好应对环境胁迫。[结论] 未来相关研究可拓展和深化以下3方面:(1)石质土壤中不同属性微生物对植物生长发育的协同作用效果以及植物的遗传适应机制;(2)寻求石质土壤环境下适宜植物生长的最佳岩石碎片参数组合;(3)未来的研究应致力于特定区域适生植物的优化筛选,选取具备强抗逆性的植物品种,以促进区域植物稳定定植,进而逐步改良并提升生态环境质量。

    Abstract:

    [Objective] This research seeks to systematically categorize, summarize, and analyze the current understanding of synergistic interactions among rocks-soil-plants. Focusing on plant adaptation mechanisms in lithified soil environments. In order to provide theoretical support and scientific evidence for the growth of vegetation and ecological environment restoration in stony habitats. [Methods] From different dimensions such as the content and burial depth of inyernal rock fragments, external vegetation types, and rainfall and climate conditions, a comprehensive analysis of the effects of rocky soil on plant growth is conducted, revealing the adaptive strategies of plants at the morphological, physiological, and molecular levels in the rocky habitats. [Results] The regulatory effect of stony soil on plant growth is closely related to factors such as rock shape, content, burial depth,climatic conditions, and plant types. The main limiting factors for plants in stony soil are soil moisture and nutrient scarcity. Under such circumstances, plants will better cope with environmental stress by regulating their own growth traits and physiological metabolism. [Conclusion] The following three aspects can be expanded and deepened in the future: the synergistic effect of different attribute microorganisms in rocky soil on plant growth and development, as well as the genetic adaptation mechanism of plants. Seeking the optimal combination of rock fragment parameters suitable for plant growth in rocky soil environments. Furthermore, future research should focus on optimizing and screening suitable plants for specific regions, selecting plant varieties with strong stress resistance to promote stable plant colonization in the area, and gradually improving and enhancing the quality of the ecological environment.
