大熊猫不仅是中国独有的珍稀动物，也在全球享有极高声誉。作为野生动物保护领域的旗舰物种，它的生存与保护已成为世界关注的生态话题。了解大熊猫，就是读懂一段关于自然、演化与共生的真实故事。
Panda: China's Living Treasure and Evolutionary Marvel
The giant panda (Ailuropoda melanoleuca) is an iconic species native exclusively to China, often called the “national treasure” and regarded as a living fossil in the animal kingdom. As a flagship species for wildlife conservation, it symbolizes the efforts to protect global biodiversity. Historically, the panda was known by other names such as “pixiu” and “mo.” Its current popular name, “panda,” was established only in modern times due to a reading habit in old Chinese script that later became standard.
Distribution and Habitat
Wild giant pandas are primarily distributed in six major mountain ranges across Sichuan, Shaanxi, and Gansu provinces—including the Qinling, Minshan, Qionglai, Daxiangling, Xiaoxiangling, and Liangshan mountains. According to China’s third national panda census, there are approximately 1,590 wild pandas in existence, with 76% living in Sichuan. Their habitat spans about 23,000 square kilometers and is concentrated at elevations of 2,600 to 3,500 meters, where bamboo grows abundantly. Because pandas prefer moist climates, fertile soils, and dense bamboo thickets, they are commonly found in valleys, basins, and river terraces with high humidity and ample cover.
Habits and Diet
The giant panda is characterized by a round body and slow movement, largely due to its need to conserve energy, as it cannot store large amounts of nutrition. It has a solitary nature, usually living alone except during the brief annual mating season. Pandas spend most of their lives roaming bamboo forests, feeding primarily on various kinds of bamboo, although their diet may also include wildflowers, vines, apples, honey, and—even occasionally—animal carrion. Pandas are highly adapted to bamboo, dedicating over ten hours each day to feeding on young shoots, stems, and bamboo shoots. Their nests are typically set up in areas with at least two bamboo species, ensuring a stable food supply should one species die off. Access to water is crucial in nest site selection, as pandas must drink daily in warmer months and even undertake long journeys in winter to find unfrozen streams.
In the wild, pandas can live to 18–20 years, while those in captivity may live beyond 30 years.
Reproduction
In captivity, female pandas reach sexual maturity at around age four and males at age six. Wild pandas mature slightly later. The mating season is from March to May, lasting two to three days. Pandas rely on scent to find mates and, once copulation is over, return to solitary lives. The species practices a polygynandrous mating system, where both males and females may have multiple partners. After mating, the female raises the cub alone.
Giant panda cubs are extremely small compared to adults, weighing only about 145 grams at birth, about 1/1000 the weight of an adult. Mothers care for their cubs for 18 months to two years, until the next offspring is born.
Conservation
China established the Wolong Nature Reserve in Sichuan as a major sanctuary for the giant panda, which now houses the country's largest captive panda research center. After the 2008 Wenchuan earthquake damaged the Wolong facilities, most captive pandas were relocated to the Bifengxia Base in Ya’an, now the world’s largest center for panda breeding and rescue.
大熊猫（学名：Ailuropoda melanoleuca）是中国特有的标志性物种，被誉为“国宝”，并在动物界被视为“活化石”。作为野生动物保护的旗舰物种，它代表着全球生物多样性保护的努力。历史上，大熊猫还有“貔貅”“貘”等称呼，如今“熊猫”这个俗称其实源于古代从右到左的汉字阅读习惯，近现代才最终固定下来。
分布与栖息地
野生大熊猫主要分布在中国四川、陕西、甘肃三省的六大山系，包括秦岭、岷山、邛崃山、大相岭、小相岭和凉山。根据全国第三次大熊猫调查，目前有约1590只野生大熊猫，其中76%生活在四川。它们的栖息地面积约为23000平方千米，集中在海拔2600至3500米间、箭竹生长茂密的区域。这里气候湿润，土壤肥沃，竹林密集，且隐蔽性好，因此常见于山谷、山洼和河岸阶地等地。
生活习性与食性
大熊猫体型圆胖，行动缓慢，主要是因为其无法大量储存能量，需要节省体力。它属于独居动物，除了发情交配期外，基本独来独往。终年穿梭于茂密竹林，以各类竹子为主食，偶尔捕食野花、藤蔓、苹果、蜂蜜，甚至动物尸体。大熊猫对竹子的依赖极高，每天多达十小时用于觅食竹子的嫩茎、嫩芽与竹笋。其筑巢地通常至少生有两种竹子，以便竹子开花死亡时有替代食物。水源也很重要，温暖季节每日饮水，冬季会长途跋涉到未结冰之处饮水。
野外大熊猫寿命通常为18至20年，圈养环境下则可超过30年。
繁殖特性
圈养条件下，雌性大熊猫约4岁、雄性约6岁性成熟，野生个体则稍晚。每年3至5月为发情期，持续2至3天。大熊猫通过气味寻找配偶，交配后即各自分开。其繁殖实行多雄多雌制，雌性只负责抚育幼崽。
新生幼崽体重仅145克左右，仅为成年体重的千分之一。雌性通常会照顾小熊猫一年半至两年，直到新后代出生。
保护状况
四川卧龙自然保护区已成为中国最大的大熊猫保护区和繁育科研基地。2008年汶川地震后，许多大熊猫转移至雅安碧峰峡基地，该地目前是全球最大的大熊猫饲养、繁育和救护乐园。
