斑苦竹无性系种群在自然林和人工林中的生态对策

Bionomic Strategies of Pleioblastus maculata Clone Population of Natural and Man-made Forests

本研究自 １９９２～１９９４年，引用Ｊ Ｌ Ｈａｒｐｅｒ（１９７７）的构件结构理论和种群生态学的原理和方法，对四川缙云山斑苦竹（Ｐｌｅｉｏｂｌａｓｔｕｓ ｍａｃｕｌａｔａ）·在无性系立竹构件种群水平上，选择生境参数，无性系种群生活史或动态参数和斑苦竹的生物学参数等三个方面的３２个指标，分析了自然林和人工林斑苦竹无性系种群。结果表明：斑苦竹对其环境表现出不同的适应特征。自然林斑苦竹无性系种群类似于Ｋ－对策种群，称为Ａ型；人工林斑苦竹无性系种群类似于卜对策种群，称为Ｂ型。“不稳定、多变的生境（人工林）系统”有利于斑苦竹的枝叶发展，可为动物园饲养大熊猫提供更丰盛的食物。

The theory of Harper' S (1977) modular structure and population ecological principles and methods are adopted to the research in this paper. The bionomic strategies of Pleioblastus maculata clone population of natural and man-made forests are studied on Jinyun Mountain, Chongqing, Sichuan Province,China,in 1992-1994,by 32 indices of habitat,clone population life-history and biology of P. maculata. The results show as follows: 1. Bionomic strategies of P. maculata clone population on Mt. Jinyun are divided into two types which are k-strategy population (A-type) in natural forest and r-strategy population (B-type) in man-made forest. 2. P. maculata on unstable and changeable habitat (man-made forest) can provide plenty of branch and leaf for zoo's panda.
