摘要: 西双版纳石灰岩植物区系是热带性质的植物区系,属于热带亚洲区系的一部分。在与邻近地区一些具体植物区系的比较上,它与热带性质的植物区系表现联系密切,并且与亚热带地区岩溶植物区系的相似性要大于非岩溶植物区系,而在热带地区,基质对区系相似性影响不明显。在与周围地区植物区系的关系上,滇南石灰岩植物区系显然与印度支那植物区系、滇东南植物区系、广西植物区系、海南植物区系以及缅甸、泰国至马来半岛植物区系均联系密切。通过区系的代表科的比较则看出,该石灰岩植物区系在发生上与云南热带-南亚热带植物区系及印度支那区系同源,在早期起源上与华夏植物区系有密切联系,在发展上受热带亚洲植物区系的渗透和强烈影响。

Abstract: Occurring at the southern-most part of Yunnan province of China, the limestone flora of Xishuangbanna is a tropical one and belongs to the part from the northern margin of tropical Asian flora. In comparison with some regional floras from neighbouring areas, it is revealed that the limestone flora has closer affinity to tropical floras. It is also revealed that the similarity coefficient between tropical floras is almost not affected by limestone or non-limestone habitat, while the similarity coefficient between subtropical floras is more affected by limestone or non-limestone habitat. In the relationships with neighbouring floras, the limestone flora shows closer affinity to the floras of Indo-China, SE Yunnan, Guangxi, Hainan, Myanmar, Thailand and Malay Peninsula. It is concluded that the limestone flora of Xishuangbanna has the same ori-gin as the floras of tropical-subtropical Yunnan and Indo-China and is possiblly derived mainly from the "cathaysian flora" in south china but strongly affected by tropical Asian nora.
