Abstract

Located in the southeast of the Qinghai-Xizang Plateau , the Western Sichuan Plateau has unique geographical and historical conditions , complicated geological physiognomy , diversified climate environments , which bear abundant and rich plant resources .The findings show :①The Western Sichuan Plateau is abundant in poplar gene resources .With 11 species of poplar , 8 varieties and 10 hybrids accounting for 45.8 % of 24 poplar species special in China , it is the natural distribution and variation center for poplar in China .②The distribution of poplar is substitutive vertically and with regional features horizontally .③Poplar have good adaptability to climate environments and distributed in vast areas ranging from dry and hot valley to moist-climate , cold and warm-climate areas.④Poplar grow very fast .Within the range of 1 600 ～ 4 000 m, poplar can grow 0.77 ～ 2.40 m in length and 1.0 ～ 3.9 cm in diameter .⑤Various floristic elements including China-Japan Flora , China-Himalayas Flora and approximate ancient tropical zone flora are coexisting in the area .⑥The area is rich in ancient trees .Poplar trees with diameter over 1.00 m are spread throughout all counties in the area .The longest diameter of poplar is 3.05 m .
