摘要
对山西省黑茶山自然保护区青毛杨林林窗特征进行了分析,结果表明,黑茶山自然保护区青毛杨林林窗形成方式以折干为主,其中由砍伐形成的最为普遍;林窗形成木基部径级主要介于10 cm^25 cm之间;林窗大多由2株形成木形成,形成木主要是青毛杨,其它树种出现较少。最后建议加强保护区青毛杨林的保护力度,以实现可持续发展和利用。
Gap characteristic of Populus shanxiensis forest was studied in Heichashan Nature Reserve.The results showed that the snapping was the main types of gap formation and the cutting was the commonest;the diameter at the base of gap formation tree was between 10 cm^25 cm;the number of gap formation tree per gap was 2 and Populus shanxiensis was main gap formation.At last, protect of Populus shanxiensis was proposed to strengthen in Nature Reserve for sistainable development and utilization .
