【摘要】 对5 a生中华楠在不同坡位、不同坡向及不同坡形的生长情况进行调查分析。结果表明:不同坡位对中华楠生长有很大的影响,下坡位生长最好,中坡位次之,上坡位最差。不同坡向对中华楠生长的影响呈现出半阴半阳坡生长最好,阴坡次之,阳坡最差。不同坡形对中华楠生长的影响表现为凹形坡>斜形坡>凸形坡。早期中华楠最适宜生长的立地因子为下坡、半阴半阳坡和凹形坡。更多还原

【Abstract】 Growth of the 5-year-old M. chinensis plantations at different slope positions,aspects,and shapes were investigated. The results showed that slope position had large effect on the growth of M.chinensis. The growth of M. chinensis was the best in down slope,and then in mid slope,the worst was in up slope. Slope aspect had relatively large effect on the growth of M. chinensis. The growth of M.chinensis was the best in semi shady and semi sunny slope,followed by shady slope,sunny slope. Effect of slope shape on the growth of M. chinensis was followed as concave slope > inclined slope > convex slope. In the early stage,optimum site condition for the growth of Machilus chinensis determined as down slope,semi shady and semi sunny slope and spill slope.更多还原
