摘　　要：以广东省惠州市惠阳区境内的生态景观林带作为研究对象,调查4个树种配置模式下的树木早期生长表现,并依据实地调查的立地条件,利用相关模型制作软件对4个不同树种配置模式下预期景观效果进行模拟。研究结果表明,惠阳区生态景观林带4个树种配置模式下的树木成活率均值为84.25%,树高、胸径和冠幅的均值分别为3.27 m、5.36 cm和1.64 m,早期生长情况较好。综合评价结果表明,4种树种配置模式中,树木早期生长综合表现较好的为模式GC1(夹竹桃、红花羊蹄甲、香樟、黄花风铃木等树种随机混交);惠阳区生态景观林带调查的9个树种树木早期生长综合表现排名靠前的为红花羊蹄甲、香樟树和美丽异木棉。总体而言,不同生态景观林带树种配置模式树木生长表现有所不同,并会产生不同的景观效果;同时,立地条件、树种选择和配置模式均会对生态景观林带公路景观效果产生明显影响。The early growth performance under 4 tree species configuration models was investigated in eco-landscape forest beh in Huiyang District, Huizhou City, and the expected landscape effects under the 4 species configuration models were simulated using related model making software in line with the site conditions concluded by field investi- gation. The results showed that the survival rate of trees under the 4 tree species configuration models in Huiyang eco- landscape forest belt was 84. 25% , and the average height, diameter at breast height and canopy were 3.27 m, 5. 36 Cm and 1.64 m, respectively, which indicated that the initial growth performance was good. Comprehensive e- valuation results showed that the growth performance of trees under model GC1 （Nerium indicum ＋ Bauhinia blakeana, Cinnamomum camphora ＋ Tabebuia chrysantha） was better than that under other tree species configuration models. Also, among 9 species in eeo-landseape forest belt, B. blakeana, C. camphora and C. speeiosaper formed better in their growth. In general, trees under different species configuration models had different growth perform- ances, and resulted in different landscape effects. In the meantime, site conditions, species selection and species configuration model have obvious effect on road landscape performance at eco-landscape forest belt.
