Cedrus libani forests have been under anthropogenic pressure for thousands of years. The unattainable topography of the Taurus mountain range (Southern Anatolia) has prevented cedar in this region from being extirpated, in contrast to its other distribution areas in Syria and Lebanon. Numerical analyses of relevés confirmed the individuality of associations, as well as the division of C. libani forests into two ecological and floristically different groups/alliances (Abieti-Cedrion and Lonicero-Cedrion). Abieti-Cedrion is distributed in the middle and eastern Taurus whereas Lonicero-Cedrion appears in the Western Taurus. The main gradients of C. libani forests were detected. It was noticed that the distribution and floristic composition of C. libani forests is strongly affected by the geographical factors. Topographical factors are also influential on their distribution. C. libani forests are fundemantal components of the Mediterranean phytogeographical region and floral elements, but under more continental conditions, where the influence of the Mediterranean climate decreased, the proportion of Iran-Turanian and Euro-Siberian floral elements increase, especially towards the east and north, as well at higher altitudes and on steeper sites.
数千年来，黎巴嫩雪松森林一直承受着人为压力。与叙利亚和黎巴嫩的其他分布区域不同，托罗斯山脉（南安纳托利亚）难以企及的地形使得该地区的雪松得以幸免。样方的数值分析证实了群落的独特性，以及黎巴嫩雪松森林可划分为两个生态和植物区系不同的组/联盟（冷杉 - 雪松组和忍冬 - 雪松组）。冷杉 - 雪松组分布在托罗斯山脉的中部和东部，而忍冬 - 雪松组出现在托罗斯山脉西部。已检测出黎巴嫩雪松森林的主要梯度。人们注意到，黎巴嫩雪松森林的分布和植物区系组成受到地理因素的强烈影响。地形因素对其分布也有影响。黎巴嫩雪松森林是地中海植物地理区域和植物区系的基本组成部分，但在更具大陆性的条件下，随着地中海气候影响的减弱，伊朗 - 图兰和欧洲 - 西伯利亚植物区系的比例增加，尤其是在东部和北部，以及更高海拔和更陡峭的地区。
