中国是世界上动植物资源种类分布最多的地区之一,据不完全统计,仅种子植物就有近300科3 200属约3万种。中国不仅拥有世界上最丰富的植物区系,也是世界生物多样性的关键地区之一。我国著名植物学家俞德浚院士曾将青藏高原地区的植物资源喻为植物王国里的一顶桂冠,而横断山地区的植物资源则是嵌在这桂冠上的一颗明珠。
China is one of the regions with the most species distribution of animal and plant resources in the world. According to incomplete statistics, there are nearly 30,000 species belonging to 300 families and 3,200 genera in seed plants alone. China not only has one of the most abundant flora in the world, it is also one of the key areas of biodiversity in the world. Yu Dejun, a famous botanist in China, once described plant resources in the Qinghai-Tibet Plateau as a crown in the plant kingdom, while plant resources in the Hengduan Mountains are a pearl embedded in this crown.
