Release cutting is ecologically and economically one of the most important silvicultural treatments for establishing a new stand. The study was designed to determine the suitable silvicultural treatments of different spacing of thinning for release cutting on young natural lebanon cedar (Cedrus libani A. Rich) stands at the thicket stage. Studies were carried out at Bucak and Gölhisar forest districts in the Western Mediterranean region of Turkey between the years of 1999-2005. Results showed that release cutting treatment had a positive effect on diameter growth for individual trees with the 1.5 m x 3 m spacing and positively correlated with spacing of thinning. However there was not significant effect of the thinning application on height growth of young natural Lebanon cedar stands.
透光伐在生态和经济方面是建立新林分最重要的造林措施之一。本研究旨在确定在幼龄天然黎巴嫩雪松(Cedrus libani A. Rich)林分处于萌生林阶段时,不同疏伐间距的透光伐适宜造林措施。研究于1999年至2005年期间在土耳其地中海西部地区的布扎克和戈尔希萨尔森林区开展。结果表明,对于株行距为1.5米×3米的单株树木,透光伐处理对其直径生长有积极影响,且与疏伐间距呈正相关。然而,疏伐措施对幼龄天然黎巴嫩雪松林分的树高生长没有显著影响。
