岷江柏种群结构及其特征研究

对川西北的理县、马尔康、金川、小金、丹巴5个县的岷江柏种群结构及特征进行研究,结果表明:该种群的36个样方中,幼苗所占的百分数均超过57%,岷江柏种群密度呈增长趋势,种群结构稳定,正向良性发展.对5个县的岷江柏种群数量特征进行比较发现,岷江柏天然林群落基本上为单优势种群群落.为此,提出了对岷江柏种群的几点保护建议.

Study on Population Structure and Characteristics of Cupressus chengiana

The results from studying population structure and characteristics of Cupressus chengiana grown in Li, Ma'erkang, Jinchuan, Xiaojin and Danba counties in Sichuan Province, showed that the sapling percentage is above 57% in 36 quadrates of Cupressus chengiana population, which indicates the population density of Cupressus chengiana presents an increment trend, the population structure is stable and develops well. The paper points out that the natural Cupressus chengiana population is basically the community with single dominant population based on analyzing quantitative characteristics of Cupressus chengiana populations from 5 counties and puts forward some suggestions for-protecting Cupressus chengiana population at the same time.
