| 摘要: |
| 对南山国家森林公园主要植被物种资源进行调查和区系结构研究。结果表明，南山国家森林公园森林覆盖率达73%，自然生态系统中目前已知的高等植物(藻菌、苔藓、地衣除外)共计有74科、251属、340种。构成镇江市区各类植被的优势成分共有约27种，其中东亚分布的种占55.6%，热带分布为主的植物占7.4%，连同东亚分布以及我国特有热带、亚热带分布为主的成分，一起可达88.9%。南山国家森林公园植被在区系组成上具有明显的亚热带特点，同时也反映出一定的过渡性，与江苏省森林木本植物区系分布特点基本一致。 |

| Abstract: |
| This paper surveyed and studied the spieces and flora of the main vegetation of Nan Shan National Forest Park. The results showed that the forest coverage rate of Nan Shan National Forest Park is about 73%. There are a total of 74 families, 251 genera and 340 species of higher plants currently known in the natural ecosystems (except algae bacteria, moss and lichen). In various vegetation in Zhenjiang, the number of dominant species is around 27, among them, the species distributed in East Asia accounts for 55.6% and that in tropic accounts for 7.4%. The propotion of speciecs distributed in East Asia and the tropical and subtropical area of China is up to 88.9%. An obvious subtropical floristic character of the vegetation in Nan Shan National Forest Park was observed, it reflects a certain transitivity as well, which is consistent with the floristic character of Jiangsu province. |
