摘要
初植密度、间伐对杉木林分优势高生长过程的影响*洪玲霞关键词杉木优势高初植密度间伐立地质量是决定林分生长和收获的主要因素之一,在用材林经营与管理中,立地质量定义为“生长在某一地位上既定树种或林分类型林木的生产潜力”。以往的研究表明:许多树种的材积生产潜...
Based on Schumacher′s dominant height growth equation,this paper studies the effects of planting density and thinning on dominant height growth in Chinese fir ( Cunninghamia lanceolata ) stands by analyzing the changes of the curve parameters.The results show that the curve parameters are significant different among different stand density while there is no significant difference among different thinning intensity,so dominant height growth curves are much affected by stand density and little by thinning intensity.
