摘要
西藏东南部的林芝地区属于世界生物多样性热点地区的东喜马拉雅区域[1],其南部为喜马拉雅山脉,北部为念青唐古拉山脉,东部与横断山脉对接,区内地质地貌复杂多样.由印度洋来的季风性暖湿气流从东南方向沿雅鲁藏布江进入林芝地区,与从西北部高原来的冷空气交汇,形成了丰富的降水和温暖的气候.
By consulting specimens and related literatures, three alien species and one new record of wild species in Tibet are identified, which belong to four genera in four families, including alien invasive species of Alternanthera philoxeroides（C. Mart.） Griseb., naturalized species of Dysphania ambrosioides （Linn.） Mosyakin et Clemants and Ipomoea purpurea（Linn.） Roth, and new record species of Polygonum orientale Linn.
