摘要
在长白山西坡的风灾干扰迹地进行永久样地连续更新调查和生境条件测定。结果表明，风灾迹地更新种群是由耐荫的红松、冷杉、鱼鳞云杉和阳性树种白桦、山杨、大青杨、大黄柳、落叶松等的混合；耐荫树种优势度趋于降低，阳性树种优势度逐年增加。风灾迹地土壤水分及碳、氮、有机质含量有所降低，人工抚育迹地生境恢复指标较天然更新迹地高。
Permanent sample plots were set up in windfall area in western slope of Changbai mountain to investigate regeneration successively and determine changes in ecological habitats. The results indicate that the composition of regeneration population is a mixture of shade-tolerant and intolerant tree species. Abundance of shade-tolerant trees tends to decrease and that of intolerant trees increases year by year. Contents of soil water, C, N and organic material in windfall plots decrease. Tendings of forest promote the restoration of habitats.
