大熊猫是本图谱二十四种之一。不是商品目录，而是把演化、解剖、行为、文化、象征、保护与分布写成一套体系。
分数是速度、智力、分布、韧性、文化影响与生态角色的相对评价，不是实验室排名。
七章分别写起源与演化、身体与感官、生活与行为、文化、传说象征、保护压力，以及与人重叠的分布。
深度导读
大熊猫 is not a single postcard animal. It is a set of populations, subspecies and human rules inside the wildlife family of this atlas.
多样性、身体、文化与分布 — 加上针对本语言区的视角。
Field guides collapse many lineages into the English word 大熊猫. Subspecies, flyways and captive lines do not share one fate -- bald eagles and Philippine eagles, or western and mountain gorillas, are the caution.
This atlas picks a Wikipedia title as the hero image and then keeps the rest of the grade in view so a recovered stock cannot launder a CR cousin.
A bear with a false thumb (radial sesamoid) for bamboo, a massive skull for grinding, and a carnivore gut on a herbivore diet -- an expensive compromise.
Hours of bamboo to extract little protein. Low activity is a budget, not laziness. Meat is rare, not a secret second life.
English-language culture met the 大熊猫 through film, law, heraldry and zoos. Those portrayals move money and sometimes take; they are not a field census.
The culture chapter dates posters and statutes so a 1975 film or a 1961 logo cannot pretend to be a 2020s Red List.
Vulnerable after a 2016 downlist from Endangered; wild numbers remain a few thousand in fragmented Sichuan-Shaanxi-Gansu belts.
Tourism, conflict payments, quotas and captive loans are dated economic bands in the market chapter -- not live prices and not a best-species prize.
生命科学深潜
大熊猫 biology is a stack of structure, energy, sensing and hard limits. The four sections below are the same headings used across the atlas so types can be compared without a best-species frame.
解剖、感官、行为与限度 — 加上本地区的田野用语。
A bear with a false thumb (radial sesamoid) for bamboo, a massive skull for grinding, and a carnivore gut on a herbivore diet -- an expensive compromise.
Load paths and tissues (not metals) are expanded in the anatomy chapter.
Hours of bamboo to extract little protein. Low activity is a budget, not laziness. Meat is rare, not a secret second life.
The how-it-works diagrams reduce that budget to a six-node loop.
Smell and a session of sit-and-grind. The false thumb is the famous morphological sense of touch on culms.
Control here means the animal steering itself -- not a vehicle ECU.
A narrow diet and a narrow map. High culture, mid resilience -- the WWF face is not a recovered generalist.
Resilience scores encode those limits relative to the other 23 types.
