中国的植物群种类极其丰富，具有很高的特有性，这使中国在北方半球的植物区系丰富度方面居首位。三个原因的结合解释了中国植物区系的丰富性。首先，中国地域辽阔，生物进化时间长，气候稳定，是北方重要的植物多样性地区。其次，中国是世界上唯一一个包括热带、亚热带、温带和北方森林之间植被连续性的国家。第三，中国的构造活动，高度解剖和提升的地理使该国成为生存，物种形成和进化的重要中心。植物多样性在中国的分布并不均匀，而是集中在中国的中南部，从约1000年到约1000年。北纬20°0′至35°0′。本文对中国中南部横断山脉、横断山脉、横断山脉和横断山脉三个局部热点地区的特有种多样性和特有程度进行了研究。与其他地区相比，中国和岭南地区值得注意。山脉其中横断植物群是中国三大热点中最丰富的。然而，所有的热点，横断山脉。C.中国和岭南地区最需要保护。
China has an extremely diverse flora with very high levels of endemism that has given China first place in the Northern Hemisphere in floristic richness. A combination of three reasons explains the floristic richness of China. First, the large area, long time for the organisms to evolve and climatic stability of China has made the country an important region of plant diversity in the Northern Hemisphere. Second, China is unique in being the country in the world that includes a region with vegetational continuity between tropical, subtropical, temperate, and boreal forests. Third, the tectonically active, highly dissected and elevated geography of China has made the country an important center of surrival, speciation and evolution. The diversity of plant is not uniformly distributed over China, but is concentrated in the south central part of China which reaches from ca. 20°0′to 35°0′ N. The diversity and levels of endemism within three localized hot spots in south central China, the Hengduan range, the C. China and the Lingnan region, are notable in comparison with other regions. The Mt. Hengduan flora in particular is the richest of the three Chinese Hot spots. However, of all the Hot spots, the Hengduan Range. C. China and Lingnan region are most in need of conservation attention.
