摘 要:极小种群植物是濒临灭绝的野生植物,需要重点关注与保护。该文从种群和个体2个层面展开综述,总结了近年来关于极小种群保护模式的研究进展,并提出以下建议:120种极小种群植物中,仍有部分植物未有相关报道,应加大相关研究;进一步加强极小种群植物致危遗传机制研究;因地制宜开展极小种群植物保护工作。

Abstract: Minimal population plants are endangered wild plants and need to be focused on and protected. This paper reviews the conservation patterns of minimal populations reported in recent years from population and individual levels, and makes the following prospects. Some of the 120 species with minimal population have not been reported, so more research should be done. Further strengthen the research on the genetic mechanism of plant risk in small population; Carry out minimal population plant protection according to local conditions.

极小种群植物是指分布地域狭窄,长期受到外界因素胁迫干扰,呈现出种群退化和个体数量持续减少,种群和个体数量都极少,已经低于稳定存活界限的最小生存种群,而随时濒临灭绝的野生植物[1]。(剩余4878字)
