| 摘要: |
| 对广东湛江红树林自然保护区范围内和周边区域的外来植物互花米草（Spartina alterniflora）
的生长分布进行了实地调查。结果显示，雷州半岛东、西海岸均有互花米草的分布，总面积达 12.6 hm2
，
徐闻海安新港码头是互花米草在中国大陆分布的最南端。调查发现，互花米草和乡土红树植物的生态位
重叠，虽然致密的红树林内未见互花米草的生长分布，但互花米草比乡土红树植物更耐淹水，表现为在
光滩前沿低潮位仅有互花米草的分布。鉴于互花米草在雷州半岛分布范围广、生境类型多样、扩散增长
迅速的现状，建议对互花米草应采取“早发现，早清除”的治理措施，并开展跟踪监测，及时掌握互花
米草的扩散动态。 |

| Abstract: |
| he exotic plant of Spartina alterniflora was surveyed across the Zhanjiang Mangrove National
Nature Reserve and adjacent areas in Leizhou Peninsula. The results showed that S. alterniflora was spreading along
the east and west coast of Leizhou Peninsula, and covered 12.6 hm2
in area. Xingang Harbor in Hai''an, Xuwen was
the most southern distribution site of S. alterniflora in mainland China. S. alterniflora overlapped with the native
mangroves along intertidal zones, but no S. alterniflora was found in the intact mangroves forest. S. alterniflora can
growth in the lower elevation in the mudflat than mangrove species, which showed that S. alterniflora can tolerance
to more inundated habitats. According to the invading condition that S. alterniflora had a broad distribution area,
occurred in diverse habitats, and a fast spread rate in Leizhou Peninsula, it''s suggested that the effective control
measures and monitoring of S. alterniflora should be taken, to help the protection of mangroves in this Region |
