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...

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.

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。

It is noted that the glaze of ice would bring heavy loss to Phyllostachys pubescens production. Therefore it is necessary to find out the cause of its occurrence and work out a preventive measure to protect it. Based on 32 years meteorological data and the actual disaster of Mao bamboo forest the author analized the relationship between these two and suggested that the abnormal of high temperature and drought weather in December of 1987 in this region was the sign of actual occurrence of glaze of ice that caused...

It is noted that the glaze of ice would bring heavy loss to Phyllostachys pubescens production. Therefore it is necessary to find out the cause of its occurrence and work out a preventive measure to protect it. Based on 32 years meteorological data and the actual disaster of Mao bamboo forest the author analized the relationship between these two and suggested that the abnormal of high temperature and drought weather in December of 1987 in this region was the sign of actual occurrence of glaze of ice that caused the great damage on Mao bamboo in February of 1988. The chief factor vulnerable to the damage of Mao bamboo is the unreasonable structure of the Mao bamboo population. Consequently, taking the scientifice management and regulating the reasonable structure of hairy bamboo population is the main concern of the technical point in prevention of hairy bamboo forest from the possible damage of the glaze of ice.

冰压危害对毛竹(Phyllostachys pubescens)生产是十分严重的,根据32年气象资料,结合危害期的实况,进行综合分析,笔者认为,影响危害程度的主要因子是竹林群体结构不合理。所以,坚持科学管理,调正竹林合理结构,是防止冰压危害的主要技术措施。

Both southwest and northwest of Sichuan are rich in bamboo resources under mid-mountain and subalpine forests in which Fargesia robusta and Bashania fangiana are giant pandas staple food. During the ecological study from 1982 to 1987. by observation of permanent quadrats and analysis on marked culm data, we found the bamboo culm's and shoot vagina's colors, and the colse relationship between leaf sheaths on main branches with the change of branch rods and the growth of bamboo culm age, which may be regarded...

Both southwest and northwest of Sichuan are rich in bamboo resources under mid-mountain and subalpine forests in which Fargesia robusta and Bashania fangiana are giant pandas staple food. During the ecological study from 1982 to 1987. by observation of permanent quadrats and analysis on marked culm data, we found the bamboo culm's and shoot vagina's colors, and the colse relationship between leaf sheaths on main branches with the change of branch rods and the growth of bamboo culm age, which may be regarded as basis to determine the culm age. Based on culm age structure, using the negative exponential model (Lny=Lny_0-bx), we may assess the growth rate and death rate of bamboo, the bamboo population dynamics, then give the basis of bemboos' growth and decline to the administration to work out protection plan for pandas.

四川西南部和西北部中山、亚高山森森下,竹源丰富,其中:拐棍竹和冷箭竹是大熊猫的主食竹种,作者1982—1987年进行竹类生态研究;通过固定样方观察和带标志茎秆记录分析,发现竹杆和笋箨的颜色,以及主枝叶鞘与枝节数的变化和竹子秆龄的增长密切相关,可以作为鉴定竹秆年龄的依据。根据竹子的秆龄结构,应用负指数函数模型(Lny=Lnyo-bx),可以估算竹子种群的增长量和死亡率,评估竹子的种群动态变化,可为主管部门制定保护大熊猫规划提供竹类资源消长的依据。
