摘要 | 选取分布于浙江南部的116个华南森林植物区系成份的代表种,根据自然地理条件的异同,在浙江南部的温州地区和丽水地区中选择5个代表性区域,分析其与华南区系的亲缘关系。在此基础上提出本区内华南、华东两个区系的划分意见:以乐清湾的清江为起点,向东超过乐清湾至温岭县南端(坞根),再经石头桥至交陈而出东海;向西南则沿北雁荡山东南山麓地带经永嘉县南端(上塘)至青田县东端(温溪),再越过瓯江向东南拐弯至瓯海(瞿溪),然后再向西南拐弯穿过文成县直至泰顺县并达于福建省边境为止。在此线以东属华南区系范围;在此线以西属华东区系范围。此外,对植物区系地理及植物区系分区与植物引种驯化的关系也进行了讨论。 |
Abstract | A suggestion about how to divide the South and the East China floristic regions in Zhejiang is put forward by selecting 116 representatives of the South China floristic elements distributed in southern Zhejiang, and choosing 5 representative areas from Wenzhou and Lishui districts in southern Zhejiang according to the difference and sameness in natural and geographycal conditions to calculate the floristic affinity between the respective representative regions and the South China flora, and furthermore by way of contrast, analysis and further research. The specific dividing is as follows. The dividing line starts at Qingjiang in Yueqing Bay, goes eastwards across Yueqing Bay to the southern end of Wenling County (Wugen), and through Shitouqiao, Jiaochen to the East China Sea; and southwestwards along the |
