摘 要：極小種群植物是瀕臨滅絕的野生植物，需要重點(diǎn)關(guān)注與保護(hù)。該文從種群和個(gè)體2個(gè)層面展開綜述，總結(jié)了近年來關(guān)于極小種群保護(hù)模式的研究進(jìn)展，并提出以下建議：120種極小種群植物中，仍有部分植物未有相關(guān)報(bào)道，應(yīng)加大相關(guān)研究;進(jìn)一步加強(qiáng)極小種群植物致危遺傳機(jī)制研究;因地制宜開展極小種群植物保護(hù)工作。

關(guān)鍵詞：極小種群;植物;保護(hù);研究進(jìn)展

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.

Key words： Minimal population; Plants; Protect; Advance

極小種群植物是指分布地域狹窄，長期受到外界因素脅迫干擾，呈現(xiàn)出種群退化和個(gè)體數(shù)量持續(xù)減少，種群和個(gè)體數(shù)量都極少，已經(jīng)低于穩(wěn)定存活界限的最小生存種群，而隨時(shí)瀕臨滅絕的野生植物[1]。（剩余4878字）
