摘要
在海滩涂上栽培秋茄、桐花树、白骨壤，经过11a的经营管理，对红树林秋茄、桐花树、白骨壤林木的生长量进行调查分析。结果表明：红树林秋茄、桐花树、白骨壤混交林的林木生长，均比秋茄、桐花树、白骨壤纯林的林木生长效果好。混交林生长的林木树高、胸径、枝下高、树冠，分别比纯林林木生长的树木高大7.69%、7.5%、11.11%，胸径粗2.17%、11.41%、6.67%，枝下高大2.01%、10.95%、8.57%，冠幅大5.00%、10.53%、13.50%。红树林秋茄、桐花树、白骨壤林木在浅潮位生长，比中潮位林木生长效果好，支柱根大、板状根系发达，吸收海水污染物强，能将盐类物质通过叶片光合作用排到植物体外，可去氮和磷等污染物，净化海边环境，防浪护堤，防止海岸侵蚀，起到保护生态环境作用。
Abstract
The cultivation of Kandelia candel,Aegiceras corniculatum and Avicennia marina in the beach, through the management of 11a,to investigate and analyze the volume growth,the Mangrove Kandelia can-del,Aegiceras corniculatum,Avicennia marina trees. The results show that:Kandelia candel,Aegiceras cornic-ulatum,Avicennia marina,mixed forest tree growth,than Kandelia candel,Aegiceras corniculatum,Avicennia marina,pure forest growth effect is good. Mixed forest trees tree height,DBH,height under branch,crown,re-spectively than those of pure forest grown trees tall and 7.69%,7.5%,11.11%,2.17%,11.41%,6.67% in di-ameter,branch 2.01%,tall 10.95%,8.57%,5%,10.53%,13.50% crown. Kandelia candel,Aegiceras cornicula-tum,Avicennia marina in the shallow water,tree growth,than the tide in forest growth effect is good,the prop roots,plate-like roots,absorb water pollutants can be strong,salts,row to plants in vitro through photo-synthesis,can go to nitrogen and phosphorus and other pollutants,purification of sea environment,anti wave support the waves,coastal erosion,to protect the ecological environment effect.
