山西五鹿山自然保护区白皮松森林群落结构研究

Study on the Community Structure of Pinus Bungeana Forest in Wulushan Nature Reserve of Shanxi Province

五鹿山自然保护区是白皮松天然种群的重要集中分布区域之一,笔者利用样方法对保护区内的白皮松森林群落结构进行了研究。结果表明,保护区白皮松的群落类型主要有油松-白皮松林、白皮松林、白皮松-侧柏林3种。其中,油松-白皮松林物种多样性最丰富。种群中出现频度和重要值较高的物种主要有油松、侧柏、辽东栎、沙棘、黄刺玫、披针叶苔草等。

Wulushan nature reserve is one of the important concentrated distribution areas of Pinus bungeana natural population,the community structure of Pinus bungeana forest in the nature reserve was studied by sampling method.The results showed that there were 3 main community types of Pinus bungeana in Wulushan nature reserve which were Pinus tabuliformis-Pinus bungeana forest,Pinus bungeana forest and Pinus bungeana-Platycladus orientalis forest.Among them,the species diversity of Pinus tabuliformis-Pinus bungeana forest was the most abundant,and the species with high frequency and important value were mainly Pinus tabuliformis,Platycladus orientalis,Quercus liaotungensis,Hippophae rhamnoides,Rosa xanthina,Carex lanceolata and so on.
