摘　　要：通过相关资料的查阅与收集,对江南油杉在我国天然种群资源的分布进行分析研究,揭示了江南油杉自然繁衍对生境的需求、过度砍伐利用是导致其濒危的原因,分析自然种群生境、染色体核型研究、育苗技术和引种驯化等方面的研究现状,以实现江南油杉资源保护与合理利用,并进一步研究江南油杉的人工林栽培技术和高效繁殖技术。By collecting and referring to related materials,the natural population resources distribution of Keteleeria cyclolepis in our country was investigated.The results showed that the reason for the K.cyclolepis endangering was the habitat requirements of natural reproduction and over-chop.The natural population habitat,chromosome karyotype research,seedling-raising technique and domesticated were analyzed to perform the conservation and reasonable utilization for K.cyclolepis resources.The further study on plantation cultivation and high efficient breeding technology of K.cyclolepis was made.
