区内二叠纪植物地理区,据李星学先生的划分,可分为安加拉区(混合区)和华夏区。鉴于区内所处的地理位置和显示出的地质环境,各地质时期的生物群在不同生物地理区中,常有混生情况。一、二叠纪植物的发育与分布据目前所掌握的资料,基本上以辉发河——富尔河——古洞河深大断裂为界,吉林省二叠纪植物化石特征显示其明显的差异。深大断裂以北属天山——兴安岭大地槽,所产的植物基本上属安加拉植物群、混有华夏植物群及欧美式植物群,属安加拉植物区
The Permian plant geographical area, according to the division of Mr. Li Xingxue, can be divided into Angara District (mixed area) and Huaxia District. In view of the geographical location and geologic environment in the area, the biota in each geologic period often has mixed status in different biogeographical areas. Permian plant development and distribution According to the information currently available, basically Huifahe - Fur River - Kwu Tung deep fault as the boundary, the Permian Jilin Province fossil plant characteristics show its obvious difference. North of the deep fault is the Tianshan - Xinganling earth trough, the plant produced basically Angara flora, mixed with Chinese flora and European flora, is a plant zone in Angara
