摘　　要：以安徽省舒城县晓天镇海拔200m左右的40年生油茶(Camellia oleiferaAbel.)林为研究对象,选择4个坡向,分别采集当年生油茶枝条和叶片,测定枝条与叶片的综纤维素、纤维素、木质素以及苯-醇抽提物含量,比较不同坡向油茶枝、叶主要化学成分的差异。结果表明,不同坡向油茶枝、叶中综纤维素、纤维素含量、木质素、苯醇抽提物含量均为南坡>东坡>西坡>北坡。油茶的内在抗逆性为南坡>东坡>西坡>北坡,这是油茶在环境压力选择下长期适应的结果。在以追求产量为目的的油茶林以营建在南坡、西南坡和东南坡为宜;在育苗基地的选择上应当选择朝阳南坡最为适宜。The experimental materrials 40 years old Camellia oleifera Abel.forest were collected from the altitude of 200 meters in Xiaotian town,Shucheng county,Anhui province,and four slope aspects were selected.To collect shoots and leaves of Camellia oleifera Abel.,the content of holo-cellulose,cellulose,lignin and benzene-ethanol of shoots and leaves were determined to compare the difference of chemical compositions among the four slope aspects of Camellia oleifera Abel..The results showed that the content of holo-cellulose,cellulose,lignin and benzene-ethanol in the shoots and leaves of different slope aspects were in the south>east>west>north.The inherent resistance of Camellia oleifera Abel.showed the trend of the south>east>west>north,which was the result of long-term adaptation of Camellia oleifera Abel.under environmental stress selection.Camellia oleifolia Abel.plantation is better be built in the south,southwest and southeast slope in order to pursue yield,and the south slope toward the sun is the most suitable choice for the seedling base.
