Research Progress on the Survival Status and Conservation Strategies of Cupressus Chengiana in China
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.
