| 摘 要： | 金花茶(Camellia nitidissima Chi)濒危的内因主要是由于其进化潜能低及对光强适应范围窄,使得种群扩散难、结实率下降和自然条件下种子转化为幼苗的效率降低;外因主要是人类对环境的破坏和对资源的掠夺式开发利用。本文系统总结金花茶濒危现状及原因,并提出保育对策:保护金花茶生存的生态系统,加强现有保护区的管理和建立新的保护区;积极开展迁地保护、回归引种和应用人工栽培技术扩大其种群等。

| Abstract: | The internal endangered reason of Camellia nitidissima Chi is the reduction of evo-lutionary potential and adaptation of narrow range of light intensity,which directly result in population diffusion,low seed setting rate and low conversion rate for seed growing to seed-lings under natural environment.The external factor of C.nitidissima is the destruction of the environment,and the exploitation and utilization of resources.We systematically summa-rized endangered status and reasons,and stated the protection strategy including ecosystem protection,strengthening management of natural reserve,establishment of new natural re-serve,ex-situ conservation,regression introduction,expanding population through artificial cultivation,and etc. |
