摘　　要：对台湾相思、大叶相思、杨梅、小叶榕和大头茶等5个树种,在粤东岩质海岸困难立地区进行了2年的造林试验。结果表明:大叶相思、大头茶和杨梅成活率高、生长快、长势好,是适宜粤东岩质海岸山地丘陵生长的优良造林树种;台湾相思成活率高,也是粤东岩质海岸优良的造林树种,但其前期生长较慢;小叶榕成活率低、生长慢,不适合作为粤东岩质海岸山地造林的优选树种。The afforestation tests of Acacia confuse, Acacia auriculiformis, Myrica rubra, Ficus concinna and Gordonia axillaries have been carried out in the rocky roast sites difficult to be afforested in eastern Guangdong province for two years. The results show that A. auriculiformis, G. axillaris, M. rubra which had thet growth characteristics of high survival rates, fast growth and good growth power, are the superior tree species which were suitable for rocky coast and hilly area in eastern Guangdong province; A. confuse which had high survival rate is also the superior tree specie, but its early growth was relatively slow; F. concinna which had low survival rate, slow growth is not suitable for rocky roast and hilly area in the eastern Guangdong province to grow.
