| 通过标本采集、鉴定和相关文献资料的查阅，对广东省韶关市新丰县鲁古河自然保护区的植物区系进行了初步研究，结果显示：该地共有野生种子植物969种，隶属于138科513属。该地区系成分以热带成分为主，区系热带性质明显。在科的分布区类型上，热带分布科占总科（除世界分布，下同）的6991%，以泛热带分布占绝对优势，占总科数的5929%；在属的分布区类型上，有15个分布区类型和14个变型，以热带分布属占优势，共有347属，占总属数的7305%，其中泛热带分布属最多，占总属数的2884%。将鲁古河保护区与邻近的5个地区植物区系进行比较发现，其与南岭、陈禾洞、梧桐山、阴那山、大雾岭都为近缘区系，其中与南岭植物区系的相似性最大，与阴那山植物区系的相似性最小。 |

| Abstract: |
| According to specimens collection, identification and relevant reference, the floristic elements and areal types of families and genera of Luguhe Nature Reserve located in Xinfeng county, Shaoguan city, north-central Guangdong province were analyzed. The results showed that, there were totally 969 species of wild seed plants belonging to 513 genera and 138 families in Luguhe Nature Reserve. The elements of the flora were complex and varied, the tropical elements were dominant and the flora was remarkably characterized by tropical zone. For areal types of families, tropical elements contributed 6991% of the total families (excluding cosmopolitan ones), in which pantropical families contributed 5929% of the total families. For areal types of genera, the flora was divided into 15 distribution types and 14 distribution subtypes, 347 genera belonging to the tropical genera contributed 7305% of the total, in which pantropical genera contributed 2884% of the total. The floristic elements of Luguhe were compared with other 5 reserves, Nanling, Chenhedong, Wutong Mountain, Yinna Mountain and Dawuling. Luguhe had the highest similarity with Nanling, and had relative low similarity with Yinna Mountain. |
