摘要
我们根据多年的实地调查结果并采用聚类分析方法对分布在哈纳斯国家级自然保护区的地衣群落进行了研究。结果表明分布在该地区的地衣种类有 10 3种 ,他们分别属于 2 0科 ,4 0属。地衣物种形成了 6种群落。同时发现该地区地衣对基物形成专一性 ,它们的基物包括 :树皮、藓丛、藓土、草地、石面、地面、土层、石浮土等。
The lichen communities in the Kanas Nature Reserve at state level in Xinjiang is researched by using cluster analysis based on the results of field investigation for many years. The results show that 103 species of liches are distributed in the nature reserve, they belong to 20 families and 40 genera respectively, and 6 lichen communities form. Distribution of the lichens is mainly affected by humidity, temperature, illumination, elevation, soil moisture, pH value of the environment, etc. Some species of the lichens distributed in the Kanas Nature Reserve have economic and medical value. These lichens are characterized by the different stages of plant evolution, indicate the pollution degree of the environment, and have a great value of exploitation and utilization. Therefore, it is suggested to strengthen management and reservation of the vegetation in the nature resreve.
