| 摘 要： | 分析红树外来种无瓣海桑(Sonneratia apetala)与本地种海桑(S.caseolaris)在热带地区混种17年后的群落结构特征,结果表明:(1)两种红树树种均适合在滩涂前缘生长,且长势良好,但无瓣海桑的长势要优于海桑,无瓣海桑树高、胸径、冠幅甲均值分别为10.6 m、15.06 cm和3.43 m,海桑为9.56 m、12.69 cm和2.23 m,两者在群落中的重要值指数分别为68.02%和24.69%;(2)群落中有秋茄(Kandelia candel)、桐花树(Aegicerascorniculatum)等乡土红树植物的自然更新现象,表明"引进种 本地种"的人工恢复模式可以促进乡土红树的更新,尤其是在滩涂前缘;(3)通过数量和立木结构分析可推测,随着群落的发展,群落中的无瓣海桑和海桑会逐渐被秋茄、桐花树等乡土物种替代,从而达到本地物种的生态恢复. |

| Abstract: | The structural features of the mangrove community of the introduced Sonneratia apetala and the indigenous S.caseolaris which have been mixed planted in the tropical area for 17 years were analyzed, with the purpose to provide a theoretical mode for restoring or rehabilitating the degraded tropical ecosystems. Both mangrove species were found to be adapted to the environment in the front edge of mud flat, but S.apetala was better in growth vigour than the S.caseolaris. The height, DBH and CB were 10.6 m, 15.06 cm and 3.43 m, respectively for S.apetala and 9.56 m, 12.69 cm and 2.23 m, respectively for S.caseolaris. The importance values of these two species in the community were 68.02 % and 24.69 %, respectively. Natural regeneration of Kandelia candel, Aegiceras corniculatum and other indigenous mangrove species were observed in the community, suggesting that the "introduced + indigenous" manmade recovery mode could accelerate the regeneration of the indigenous mangrove species, especially on the front edge of the mudflat. Analysis of the tree quantity and stocking structure of the community showed that S.apetala and S.caseolaris would be gradually replaced by the indigenous species, such as K.candel, A.corniculatum and others,with the development of the community,to form a community of the indigenous species. |
