作文国宝大熊猫英文回答：The giant panda (Ailuropoda melanoleuca) is a large, black and white bear native to central China. It is a member of the family Ursidae, which also includes the black bear, brown bear, and polar bear. Pandas are known fortheir distinctive black and white fur, as well as their love of bamboo.The giant panda is a relatively large bear, with adults typically weighing between 75 and 150 kilograms (165 and 330 pounds). Males are typically larger than females. Pandas have a thick, black and white coat, which helps them to stay warm in their cold, mountainous habitat. They have a large, rounded head with small ears and a short snout. Pandas have a large jaw with strong teeth, which they use to chew tough bamboo stalks.The giant panda is found in temperate forests in themountains of central China. They are most commonly found in the provinces of Sichuan, Shaanxi, and Gansu. Pandas live in a variety of habitats, including forests, bamboo groves, and grasslands. They are solitary animals, and they spend most of their time feeding and sleeping.The giant panda is an herbivore, and its diet consists almost exclusively of bamboo. Pandas eat a variety of bamboo species, but they prefer the leaves and shoots of the giant panda bamboo (Phyllostachys edulis). Pandas have a specialized digestive system that allows them to digest the tough bamboo stalks. They have a large stomach and a long intestine, which helps them to break down the bamboo fibers.The giant panda is an endangered species, and its population is estimated to be around 1,864 individuals in the wild. The main threats to pandas are habitat loss, poaching, and climate change. Habitat loss is the biggest threat to pandas, as their natural habitat is being destroyed by logging, agriculture, and mining. Poaching is also a major threat to pandas, as they are hunted for theirfur and meat. Climate change is also a threat to pandas, as it is causing their habitat to change and become less suitable for them.The Chinese government has made a number of efforts to protect pandas and their habitat. These efforts include the establishment of protected areas, the ban on poaching, and the promotion of sustainable forestry practices. The Chinese government has also worked with other countries to establish panda breeding programs.The giant panda is a beloved animal, and it is a symbol of China. It is a reminder of the importance of conservation, and it is a hope for the future of our planet.中文回答：大熊猫（学名，Ailuropoda melanoleuca）是一种大型黑白相间的大型熊类，原产于中国中部。

放归大熊猫Ailuropoda melanoleuca预选栖息地评估【摘要】：大熊猫(Ailuropodamelanoleuca)迁地保护的真正目的是在圈养种群达到一定规模后,经过野化训练,将其逐步放归野外,以减少圈养压力、增加遗传多样性和复壮野生种群,补充、支持和促进就地保护,达到长期保存该物种的目的。

栖息地是野生动物生存繁衍的物质基础,其质量结构的优劣影响野生动物的种群发展。

对预选的大熊猫潜在放归栖息地进行评估,是整个放归研究的重要内容。

本研究基于放归目的,采用样线法和样方法,于2004年冬——2006年春对中国建立最早、规模最大的、圈养大熊猫种群数量最多的预选放归栖息地——卧龙自然保护区进行了历时近2年的3次野外调查,得到了如下成果和结论:(1)总结、回顾了大熊猫生境选择的研究进展,为确定栖息地评估标准提供了参考。

(2)在整个保护区有代表性地选设了5个地点、17条样线,对各种生物的和非生物的生境因子进行了规模不等的三次全面调查(三次调查的样方数分别为189、239、94),基本摸清了影响大熊猫生存的生境因子的时空动态规律。

(3)首次基于较大规模的调查(239个大样方)计算出了大熊猫及其各种伴生动物在不同生境因子上的生态位宽度指数及各种伴生动物与大熊猫的生态位重叠指数。

首次同时计算出了大熊猫及其各种伴生动物对各生境因子的选择指数。

(4)通过对2个地点18个取样点1350株冷箭竹、2个地点13个取样点174株拐棍竹、1个地点5个取样点75株华西箭竹标准竹的每株检尺,推导出了三种竹的一年生、二年生、多年生单株竹地上部分生物量(鲜重和干重)及单株竹地上部分各器官生物量(鲜重和干重)关于竹基径和高度的一元、二元、三元回归模型。

其中,二元幂函数回归模型由于综合了准确性高和操作简便的优点,因而相对来说是最优的模型。

(5)运用上述二元幂函数回归模型,结合野外调查,研究了卧龙冷箭竹、拐棍竹、华西箭竹的单位面积生物量(生物量密度),并据此估算出了整个卧龙保护区冷箭竹和拐棍竹的现存量。

大熊猫（学名：Ailuropoda melanoleuca，英文名称：Giant panda），属于食肉目、大熊猫科的一种哺乳动物，体色为黑白两色，它有着圆圆的脸颊，大大的黑眼圈，胖嘟嘟的身体，标志性的内八字的行走方式，也有解剖刀般锋利的爪子。

是世界上最可爱的动物之一。

大熊猫已在地球上生存了至少800万年，被誉为“活化石”和“中国国宝”，世界自然基金会的形象大使，是世界生物多样性保护的旗舰物种。

据第三次全国大熊猫野外种群调查，全世界野生大熊猫不足1600只，属于中国国家一级保护动物。

截止2011年10月，全国圈养大熊猫数量为333只。

大熊猫最初是吃肉的，经过进化，99%的食物都是竹子了，但牙齿和消化道还保持原样，仍然划分为食肉目。

野外大熊猫的寿命为18～20岁，圈养状态下可以超过30岁。

是中国特有种，现存的主要栖息地是中国四川、陕西和甘肃的山区。

The Giant Panda,scientifically known as Ailuropoda melanoleuca,is an iconic and beloved species native to China.Renowned for its distinctive black and white fur,the panda has become a symbol of wildlife conservation efforts worldwide.Habitat and Distribution:Giant Pandas are primarily found in the mountainous regions of central China, particularly in the provinces of Sichuan,Shaanxi,and Gansu.They inhabit dense bamboo forests at elevations ranging from5,000to10,000feet,where their diet mainly consists of various species of bamboo.Diet:Bamboo makes up over99%of a pandas diet.They have a unique digestive system adapted to process this fibrous plant,although it is not the most efficient in terms of energy conversion.Due to the low nutritional content of bamboo,pandas spend a significant portion of their day eatingup to14hoursto meet their energy needs. Behavior:Pandas are generally solitary animals.They communicate with each other through vocalizations,body language,and scent marking.Males and females come together during the breeding season,which is short and occurs once a year.Cubs are born blind and helpless,relying on their mothers for warmth and protection for the first few months of their lives.Reproduction:Reproduction in pandas is challenging due to their low reproductive rates and specific mating behaviors.Female pandas are only in estrus for a short period each year,and the gestation period is around95to160days.Cubs are often born in pairs,but the mother typically raises only one,as they are born very small and vulnerable. Conservation Status:The Giant Panda was once classified as an endangered species due to habitat loss, poaching,and a low birth rate.However,thanks to extensive conservation efforts, including reforestation and the establishment of nature reserves,their status has been upgraded to vulnerable by the IUCN.Cultural Significance:In Chinese culture,the panda is considered a national treasure.It is often used as a symbol of peace and friendship,and pandas have been gifted to other countries as a diplomatic gesture.The species is also a significant figure in global conservation, representing the importance of protecting biodiversity and natural habitats.Conservation Efforts:Various organizations,including the World Wildlife Fund WWF,have been instrumental in the conservation of the Giant Panda.Efforts include habitat preservation,antipoaching initiatives,and captive breeding programs aimed at increasing the panda population and reintroducing them into the wild.In conclusion,the Giant Panda is a remarkable species that has captured the hearts of people around the world.Its conservation is a testament to the power of international cooperation and the dedication of scientists,conservationists,and everyday citizens to protect our planets precious wildlife.。
