China is one of the richest countries in terms of plant diversity with approximately 35,856 high plants species, the third largest plant species in the world, about 10% of the world’s total, having 2,129 species of Lycopodium japonicum and Pteridophyta, 237 species of Gymnosperm, 28,996 species of Angiosperm etc. As one of the fourorigin areas of cultivated plants, China is the country of origin of many important agricultural crops and fruit trees. More than 7,500 species of garden flower plants are cultivated in China, and almost all the genre of temperate woody plants can be found in China. Due to habit loss and fragmentation, pollution, excessive use of natural resources, competitive interactions with invasive species and climate change, the plant diversity in China is increasingly threatened, with an estimated 3,879 plant species being threatened.
