| 摘要: |
| 在多次野外调查和历史资料查询的基础上，整理出峨边黑竹沟自然保护区种子植物名录，并对其进行了区系分析。结果表明：黑竹沟自然保护区种子植物共135科693属2 246种，其中裸子植物7科15属38种，被子植物128科678属2 208种。在科级上可划分成9个分布区类型和13个变型，以热带成分为主；属级上分成14个类型和22个变型，以温带成分为主，说明保护区的区系成分具有过渡性，区系复杂。保护区与滇藏高原共有物种较多，区系起源有一定的古老性。与周边保护区的种子植物区系特征进行比较，发现黑竹沟与老君山自然保护区最相似。 |

| Abstract: |
| On the basis of many field investigations and historical data inquiries， a list of seed plants in Heizhugou Nature Reserve in Ebian was sorted out， and its flora was analyzed. The results show that there are 2 246 species of seed plants belonging to 693 genera and 135 families in Heizhugou Nature Reserve， including 38 species of gymnosperms belonging to 15 genera and 2208 species of angiosperms belonging to 678 genera and 128 families. At the family level， it can be divided into 9 distribution types and 13 variants， mainly tropical components. There are 14 distribution types and 22 variants at the genus level， with temperate elements as the main ones， indicating that the flora of the reserve is transitional and complex. There are many species in the reserve and Yunnan-Tibet Plateau， and the origin of flora has a certain antiquity. Compared with the floristic characteristics of seed plants in the surrounding reserves， it is found that Heizhugou and Laojunshan Nature Reserve are the most similar. |
