摘　　要：对张家界国家森林公园内杉木过熟林地内景观植被天然更新开展了调查研究。结果表明,杉木林冠下演替层已经初步形成,研究区内参与演替的景观植被种类达55种,生长势良好,景观价值高;但分布不均匀,密度低。为保证其今后景观价值,应从林内卫生、遗传物质人工诱导、种群竞争机制等方面入手,应尽快开展园内景观植被诱导恢复工作。The natural vegetation regenation from the over maturity planted China fir forest in Zhangjiajie national forest park was investigated.Results show that the initial vegetation regeneration layer is formed and 55 tree species involved.The vegetation grows well,has high landscape value,but has the uneven distribution and low density.To insure the future forest landscape value,it is suggested to carry out as soon as possible in the aera of forest sanitation,genetic material artifical induction and population competitive mechanism.
