The bamboo Fargesia nitida, one of the giant panda's main food sources and the dominant shrub species of the forest understory, is mainly distributed in the dark coniferous belt in western Sichuan and southern Gansu in China.
      
Sequence variation and genetic diversity in the giant panda
      
About 336-444 bp mitochondrial D-loop region and tRNA gene were sequenced for 40 individuals of the giant panda which were collected from Mabian, Meigu, Yuexi, Baoxing, Pingwu, Qingchuan, Nanping and Baishuijiang, respectively.
      
The results showed that the giant panda has low genetic variations, and that there is no notable genetic isolation among geographical populations.
      
The ancestor of the living giant panda population perhaps appeared in the late Pleistocene, and unfortunately, might have suffered bottleneck attacks.

Study of the digestive rate of coarse cellulose of giant pandas
      
The effects of bamboo powder on Giant pandas digestive organs and digestive physiology, digestive rate of coarse cellulose of different bamboo species, the difference in digestive functions among individual Giant Panda needs further studies.
      
Lethal factors of diseases and protective countermeasures of wild and penned Giant pandas
      
In order of reducing percentages, other diseases are roundworm disease, toxicosis, epilepsy, etc., Based on the statistics of 22 penned giant pandas, the death out of the digestive system diseases comes first, accounting for 63.64%.
      
The mortality of the sub-adults is the highest, accounting for 64.29%, or 2.6 times as that of the adults, or 7 times as that of the aged giant pandas.

In this paper, we discussed the adaptabilities of 25 bamboo species introduced into Wanglang and Wolong Reserves from differ- ent altitudes and forest types. The indexes included survival rate of first and second year, bamboo shooting rate, adult bamboo formed rate as well as average value of these four indexes. Based on the average value of 3 year observations we learnd that Yushania line- olata, Fargesia ruta, F. scabrida, bashania targesis, F. denudata and Y. lineolata grew well in Wanglang and were suitable...

In this paper, we discussed the adaptabilities of 25 bamboo species introduced into Wanglang and Wolong Reserves from differ- ent altitudes and forest types. The indexes included survival rate of first and second year, bamboo shooting rate, adult bamboo formed rate as well as average value of these four indexes. Based on the average value of 3 year observations we learnd that Yushania line- olata, Fargesia ruta, F. scabrida, bashania targesis, F. denudata and Y. lineolata grew well in Wanglang and were suitable to the environs of Wolong. They prefer the forestland with canopy densities of 0.5--0.7. The altitude was another factor affecting bamboo growth and survival. The bamboos having strong adaptabilites had characteristics of moisture-like, good tolerance to acid soil, low temperature and drought, but this varied from place to place and species to species.

本文通过在四川平武王朗和卧龙自然保护区的25种大熊猫主食竹类引种试验,对不同海拔高度不同植被类型竹种的适应性与差异性进行了研究。重点观测分析了成活、保存、生笋、成竹率四项成效指标综合值及枝叶生长发育情况,并按综合值高低排列名次。三年筛选结果,在王朗引种效果较好的竹种是石棉玉山竹Yushanialineolata、青川箭竹Fargesza rufa、糙花箭竹F.Scabrida、冷箭竹Bashania fangiana,卧龙表现好的有缺苞箭竹F.denudata和石棉玉山竹Y.lineolata。引种地宜于0.5—0.7中等郁闭度的暗针叶林和桦木次生林下为佳;海拔和类型因素对竹种成活与生长都有明显影响。适应性强的种类具有喜湿耐酸耐低温的卷叶抗旱特性,既有不同程度的适应性,也有地区间与种间的差异性。

Arrow Bamboo (Bashania fangiana) only distrbutes in the western mountains of the Sichuan Province, growing in the mixed forests of coniferous and broadleaf trees and under subalpine needl forest at about 2100—3600 metres above sea level. This kind of bamboo in Qionglai mountains is Giant Panda's staple food. In 1983, Arrow Bamboo was flowering, seeding and dying-off, and the flowered area was about 65 to 95 percent of the total area in which Arrow Bamboo distributed. Aecording to the history, Arrow Bamboo flowers every 50 to 60 years. It will take over 10 years for the seed to become adult bamboo. As a result, the Giant Pandas in this area have a periodic food crisis. Therefore, studying the seed charaeteristics and the regeneration of the seedlings and using some methods to improve their regeneration and rehabilitation are not only the need of the study on its characteristics of bio-ecology, but also strategic measures. for the research, conservation and population development of Giant Pandas. This article describes the characteristics of the seeds of Arrow Bamboos: net percent, water containing, weight of 1000 seeds, living ability, rate of sprout, resting period and life span of the seeds. It also describes the growth of the bamboo seedlings: seed quantity on the ground during the natural regeneration; lasting time of the sprouts; growth of the seedlings; seedling amount trends in the early period of the regeneration; the rate of the living seedlings; and the growth and changes of the seedlings. So the general principles of the life activity of the seeds and the growth of Arrow Bamboo seedlings have been found, providing the Scientific basis for artificial improving Arrow Bamboo's natural regeneration in high mountains.

冷箭竹(Bashania fangina)为四川西部特产,分布于海拔2100~3600米之针阔叶混交林和亚高山针叶林下,是邛崃山系大熊猫的主食竹种。1983年,该竹种发生大面积的开花、结实而枯死,开花面积占竹子分布总面积的65~95%。据史书记载,冷箭竹的开花周期为50~60年。竹种萌发成林约需10年以上时间,从而导致以此为食的大熊猫发生周期性的食物危机。因此,研究冷箭竹的种子特性及幼苗更新规律,采取人为措施加速幼苗的更新复壮,这不仅是研究该物种生态生物学特性的需要,也是保护大熊猫,促进其种群繁衍的主要途径。本文描述了冷箭竹种子的净度、含水量、千粒重、生活力、发芽率、休眠期和生命期限等特性,并介绍了该竹和在自然条件下林地上的种子数量、种子发芽持续时间、幼苗更新的期数量的动态变化、幼苗成活率和幼苗的生长变化。通过这些研究,初步掌握了冷箭竹种子生命活动的一般规律和幼苗生长的基本特征,为提高高山地区冷箭竹的自然更新能力提供了科学依据。

Atomic absorption spectrophometric method was used to determine the 7 kinds of trace element (Cu、Zn、Mn、Fe、Ca、Mg、K) in 256 samples of the giant panda's staple food bamboo: leaf. Shootculn, annual culm, biennial culm, root and rhizome of Bashania fangiana. Fargesia robusta, Fargesia nitida and Yushania Chungii in Wolong Natural Reserve. It showed the relationship between the trace element contents with species, age. Positions and habitat (altitude、season) of bamboo stand.

用原子吸收分光光度法测定了四川卧龙自然保护区大熊猫主食竹种——冷箭竹(Bashania fangiana)、拐棍竹(Fargesia robusta)、华西箭竹(Fargesia nitide)、峨眉玉山竹(Yushania chungii)的叶、笋—幼竹、一年秆、二年秆、根、鞭共256例中的铜、锌、锰、铁、钙、镁、钾等七种元素含量。找到了微量元素含量与竹类、竹龄、竹株部位、竹的生长环境(海拔高度、季节)等的关系。
