冷箭竹生物生产量的研究

本文采用卧龙五一棚大熊猫生态研究区85个产量样方中,冷箭竹单株茎高、基径、湿重和干重等数据,建立了冷箭竹单株湿重的经验公式和湿重与干重的折算公式,为研究冷箭竹地上部分的生物生产量和种群动态提供了科学依据。

A STUDY ON THE BIOMASS AND THE FRODUCTIVITY OF BACHANIA FANGIANA

Bachania fangiana, a subalpine bamboo, is the favourite food for the giant panda. It is significant to research the biological productivity of the shoot for detecting the developing of the giant panda population, the evolving of the bamboo population and the relationship bettween the giant panda and the bamboo ecology. With the data of the height of single shoot, the wet and the dry weight of the bottom of culm from 85 plots in wuyibong, wolong, the author has set up the experience equation about measuring the weight of a single shoot and the equation about converting a wet into a dry weight. The result provides a scientific basis for further researching the development of Bachania fangiana population.
