摘　　要：为探索适宜粤东地区潮间带深水区红树林造林树种,选择5个树种,在不同水位浸淹下(退潮裸露、退潮水深0~20 cm和退潮水深20~40 cm)进行了1年的造林试验。结果表明,5个树种对水位条件的敏感度强,随着退潮水位的加深,5个树种的保存率和年生长量逐渐降低;桐花和白骨壤的保存率高、生长快、长势较好,是适宜粤东地区潮间带深水区的优良红树林树种,秋茄、木榄和红海榄在退潮裸露区域可以正常生长,而在深水位地区则不宜种植;垫高种植,能明显提高红树林幼树的保存率,促进其生长。In order to explore the suitable tree species of mangrove in intertidal deep water area of eastern Guangdong,the afforestation tests of five tree species were carried out in different levels of flooding for one year bare at low tide,0~20 cm deep at low tide and 20~40 cm deep at low tide.The results showed that the five species were highly sensitive to water level conditions,with the deepening of the ebb water level,the survival rate and annual growth of the five tree species decreased gradually;Aegiceras corniculatum and Avicennia marina which had the high survival rates,fast growth and growing well,were the superior tree species of mangrove suitable for intertidal deep water area of eastern Guangdong,while Kandelia candel,Bruguiera gymnorrhiza and Rhizophora stylosa could grow normally in the bare area of low tide,but should not be planted in the deep water area;by increasing the height of planting land,the preservation rate and growth of mangrove saplings could be significantly improved.
