大熊猫的生活奥秘

在大自然中，大熊猫历经数百万年的生活磨练，过着非常独特的生活，大熊猫独自固守着数平方公里的家园，成天在这个独立王国里游荡，食不分昼夜，睡不择场地，只求吃得饱，睡得酣，游得欢。不过，当春暖花开时，它们也会打破各自的鸿沟，追慕异性。交配后又各自返回自己的领地，幽居独处。

鹤鸵：比大熊猫稀少的超级猛禽

说到危险的鸟类,人们首先往往会联想到在天空中翱翔的雄鹰,或是在林间捕鼠捉蛇的夜枭——这两种鸟类虽然凶猛,但也能为人类所驯化。而在巴布亚新几内亚森林中,却生活着一种不为人知的鸟类——鹤鸵,它虽然不会飞,却远比鹰和夜枭更为凶猛,并且桀骜不驯,如果你不小心惹了它,这些家伙就会毫不犹豫地向人发起攻击!

乌蕨孢子繁殖技术的研究

研究了乌蕨(Stenoloma chusanum(L.)Ching)孢子无菌繁殖和常规繁殖方法。结果表明,乌蕨孢子在1/4MS培养基培养时的萌发率最高,达85.3%;在1/2MS培养基中的配子体成苗率最高,达85.9%;1/2MS培养基是培养优质孢子体苗的最佳培养基;河沙与草炭土体积比为1∶1的混合基质是播种孢子的理想基质,孢子萌发率和配子体成苗率分别达到82.6%和73.4%;无菌繁殖和常规繁殖所得的幼孢子体苗移栽成活率均达90%以上。     

Distribution of Economic Benefits from Ecotourism: A Case Study of Wolong Nature Reserve for Giant Pandas in China

Ecotourism is widely promoted as a conservation tool and actively practiced in protected areas worldwide. Theoretically, support for conservation from the various types of stakeholder inside and outside protected areas is maximized if stakeholders benefit proportionally to the opportunity costs they bear. The disproportional benefit distribution among stakeholders can erode their support for or lead to the failure of ecotourism and conservation. Using Wolong Nature Reserve for Giant Pandas (China) as an example, we demonstrate two types of uneven distribution of economic benefits among four major groups of stakeholders. First, a significant inequality exists between the local rural residents and the other types of stakeholder. The rural residents are the primary bearers of the cost of conservation, but the majority of economic benefits (investment, employment, and goods) in three key ecotourism sectors (infrastructural construction, hotels/restaurants, and souvenir sales) go to other stakeholders. Second, results show that the distribution of economic benefits is unequal among the rural residents inside the reserve. Most rural households that benefit from ecotourism are located near the main road and potentially have less impact on panda habitat than households far from the road and closer to panda habitats. This distribution gap is likely to discourage conservation support from the latter households, whose activities are the main forces degrading panda habitats. We suggest that the unequal distribution of the benefits from ecotourism can be lessened by enhancing local participation, increasing the use of local goods, and encouraging relocation of rural households closer to ecotourism facilities.     

大熊猫主食竹种秆龄鉴定及种群动态评估

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，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规

Sustainability evaluation of the Grain for Green Project: from local people's responses to ecological effectiveness in Wolong Nature Reserve

This article examines the sustainability of the Grain for Green Project in the Wolong Nature Reserve. Pertinent data were collected through a questionnaire survey and a spatial analysis of reforested lands. The study results identified four critical issues that may influence the sustainability of the project in the study area. The first issue is concerned with the project’s impacts on local sustenance. Because local grain consumption depends greatly on compensation awarded by the project, the potential for sustainability of the project is compromised. The second issue is that the project causes negative effects on local incomes in the Wolong Nature Reserve, which may undermine local economic prospects. The third issue is that the project failed to deliver suitable habitat for the giant panda, although two of the suitability requirements that deal with landform features were met. Lastly, the project neglects great differences among geographical areas in the country, providing the same compensation and length of compensation period to all participants. Appropriate compensation mechanisms should be established and adapted to local economic, environmental, and social conditions. In managing nature reserves and moving toward sustainability, ensuring all aspects of local socioeconomic and ecological/environmental issues are properly addressed is a real challenge. Based on our study, some recommendations for improving sustainability of the project are given.
