摘　　要： 通过野外调查,和查阅相关文献标本,对云南的枇杷属植物种类、地理及垂直分布情况有了基本的了解。调查结果表明:目前,云南野生枇杷属资源共有16个种、变种及变型。其中种为13个,占全国16个种中的81.25%;变种或变型3个,占全国5个变种或变型的60%。其中,椭圆枇杷在云南首次被发现。依据云南枇杷属植物本身的分布特点,并参照植被和自然条件状况,云南枇杷属植物大致可以分为4个分布区:Ⅰ滇南、滇西南小区;Ⅱ滇东南小区;Ⅲ滇中高原小区;Ⅳ滇西、滇西北横断山脉小区。通过对云南与它邻近地区和国家的野生枇杷属资源的比较,发现云南省的枇杷属植物种类最多。因此云南是我国枇杷属植物的现代分布中心和基因中心。 The Eriobotrya Lindl. flora and its geographical distribution in Yunnan were studied based on the literature, herbarium specimens and field investigation. The results show that there are 16 species or variants in Yunnan, among which 13 are species accounting for 81.25% of the total 16 species in China, and the rest 3 are variants accounting for 60% of the total 5 varieties in China. Among them, E. elliptica Lindl. was found in Yunnan for the first time. Based on the vegetation, natural conditions and the distribution features of Eriobotrya in Yunnan province, its geographical distribution can be divided into 4 regions： Regions Ⅰ covers southern and southwestern Yunnan ; Regions Ⅱincludes southeastern Yunnan ; Regions Ⅲ is the central plateau; and Region Ⅳ covers Western and northwestern Hengduan Mountain range. Compared with the neighboring regions or countries, Yunnan has the richest germplasm resources of Eriobotrya. The above analysis suggested that Yunnan province is a distribution center as well as a gene center of Eriobotrya in China.
