摘要
猪头尖山区植物资源丰富，现有种子植物116科（裸子植物4科，被子植物112科），502属，1010种（包括变种、亚种）。从种子植物属的分布区类型分析，本区具有我国15个种子植物属的分布区类型的全部，表明与世界各地植物区系联系紧密。本区含有丰富的泛热带属，但仍以北温带成分占优势，且中国特有属中的野生木本属全是落叶乔木或灌木，表明本区植物区系的性质偏重于北温带性质。
Zhutoujian Mountainous Region is rich in plant resources. There are 1010 species(including varieties, subspecies) of 502 genera in 116 families (4 families of Gymnosperms ,112 families of Angiosperms ) of seed plants. According to the analysis of distribution type,there are 15 distribution type in the region, the same as thOSe in China, which can be explained that the flora of Zhutoujian Mountainous Region is very near to that of all over theworld. The Zhutoujian Mountainous Region is rich in Pantropic genera, but the dominant genera is North Temperate, and all of the wild trees of endemic genera to China are deciduous, sothe flora of Zhutoujian Mountainous Region is biased towards North Temperate.
