摘　　要： 雷州半岛位于中国大陆最南端，拥有9284.3ha^2红树林，分布于100多处内湾或开阔海岸；其红树林有大型藻类69种，13种乡土真红树植物和9种乡土半红树植物，其它伴生植物100多种；另有引进7种真红树植物，其中无瓣海桑为速生外来树种，在当地人工红树林中占优势。红树林生境多样主要呈小斑块状分散分布，主要有17种群落类型，面临因人为活动和沿海污染的严重干扰，减弱了其作为过境鸟类栖息地的作用，因此，迫切需要采取有效的红树林保护措施。图1表4参18。 Leizhou Peninsula, located at southem end of mailand China, has 9 284.3 ha mangrove distributed more than 100 sites along its inlets and open coastlines. This paper presents the surveys on mangrove area in Leizhou Peninsula during 2000 and 2008, especially the survey in the eight major mangrove areas in 2002. The flora recorded in mangrove systems includes 69 large algea species, 13 native true mangrove species, nine native semi-mangrove species, and another seven intoduced true mangrove species with Sonneratia apetala as the quickest growing exotic mangrove species dominatant in the mangrove plantations, and more than 100 land flora species, consisting of 17 main mangrove associations. The plant biodiversity habitats remained mainly small patches and diverse, and were becoming worse under the intensive disturbance of human acitivities and coastal pollutions, which decreased the value of mangrove coasts as the important sites for flying-by migrating birds in Leizhou Peninsula. The effective mangrove conservation measures should be implemented.
