摘　　要：岷江柏(Cupressus chengiana)是国家二级重点保护植物,具有生态、经济和美学价值,是川西干旱河谷地区的维持生态平衡的主力植物物种之一。了解岷江柏生存现状并制定相应保护策略刻不容缓。本文采用文献检索与综合分析的方法,总结岷江柏的生存状态、潜在的致危因素及其保护现状,并在此基础上提出相应的保护策略。文献分析表明:(1)岷江柏的生存面临诸多干扰因素,其中人为干扰是最主要的因素,包括生态污染、非法砍伐等。此外,种子繁育特性、气候变化、栖息地恶化及遗传变异等因素,也是岷江柏面临的主要威胁。(2)岷江柏的保护措施不足,应采取以就地保护为主,适度进行迁地保护,并辅以生态修复以改良栖息地环境的保护策略。(3)扩建岷江柏保护区、人工移栽、采种育苗结合入库保存等方式,均能有效保护岷江柏种群资源。(4)另外,还应研发岷江柏木人工繁育技术,制订相关法律法规并加大对民众的科普力度。本文可为岷江柏及该区域其他珍稀植物的保护提供理论依据和实践指导。Cupressus chengiana,one of protected plants of national class II,possesses ecological,economic,and aesthetic values.It serves as one of pivotal native species in maintaining ecological balance in the arid river valleys of western Sichuan,China.Understanding the current survival status of Cupressus chengiana and formulating corresponding conservation strategies is of utmost urgency.This paper summarized the survival status,potential threatening factors,and current conservation efforts of Cupressus chengiana through literature retrieval and comprehensive analysis,and on this basis,proposed corresponding protection strategies.(1)The survival of Cupressus chengiana faces many interference factors,among which human disturbances are the primary ones,including ecological pollution and illegal logging.In addition,factors such as seed breeding characteristics,climate change,habitat degradation and genetic variation also pose significant threats to Cupressus chengiana.(2)Insufficient conservation measures for Cupressus chengiana persist.It is essential to prioritize in situ conservation,supplement with ex situ conservation where appropriate,and couple this with ecological restoration to improve habitat conditions.(3)Expanding Cupressus chengiana reserves,conducting artificial transplantation,and combining seed collection and seedling cultivation with storage in seed banks can effectively protect the population resources of Cupressus chengiana.(4)Furthermore,research and development of artificial propagation techniques for Cupressus chengiana should be undertaken,while relevant laws and regulations should be formulated and public education efforts intensified.This paper provides administation foundations and practical guidance for the conservation of Cupressus chengiana and other rare plants in the region.
