摘　　要：通过野外调查和查阅文献资料,获取了南涧大龙潭水源林州级自然保护区植物资源信息,从植物种类、区系等方面对植物多样性进行了分析。结果表明:保护区内共记录种子植物84科219属379种,其中裸子植物2科3属4种,被子植物82科216属375种;在属级和种级水平上,种子植物区系均为典型的温带性质。有云南省二级保护野生植物1种,中国珍稀濒危保护植物1种,中国受胁高等植物1种,CITES附录Ⅱ植物3种。针对保护区植物多样性特征,提出了加大对珍稀、濒危野生植物的保护力度,积极开展科学研究和科学普及工作等保护建议。Through field investigation and literature review, the plant resource information of Nanjian Dalongtan Water Source Forest State Nature Reserve was obtained, and the plant diversity in the reserve was analyzed from plant species, flora and other aspects. The results showed that 379 species of seed plants belonging to 219 genera and 84 families were recorded in the reserve, including 4 species of gymnosperms belonging to 3 genera and 2 families, and 375 species of angiosperms belonging to 216 genera and 82 families. On the level of genus and species, the flora of seed plants is typical temperate. There are 1 wild plant under secondary protection in Yunnan Province, 1 rare and endangered plant under protection in China, 1 threatened higher plant in China, and 3 CITES Appendix II plants. In view of the characteristics of plant diversity in the reserve, suggestions are put forward to strengthen the protection of rare and endangered wild plants, and actively carry out scientific research and scientific popularization.
