摘要:

]以广东省惠州市惠城区内3号和10号生态景观林带为研究对象，通过小班调查5个样点内不同树种配置模式的树木早期生长表现，结果表明，惠城区生态景观林带5个样点的树木成活率均值为87.8%，树高与胸径均值分别为2.6 m和7.5 cm，早期生长情况总体较好；综合评价结果表明，5个样点的树木早期生长综合表现排名顺序为：龙丰>水口>汝湖>小金口>白鹭湖；不同树种配置模式保存的树木生长表现综合评价结果表明，3号生态景观林带综合排名前3的树种配置模式分别是314、318、32，其中模式314保存的造林树种为凤凰木、黄槐、鸡冠刺桐、樟，模式318保存的树种有凤凰木、樟，模式32保存的树种有大叶紫薇、凤凰木、黄槐、樟；10号生态景观林带树木生长表现综合排名前3的分别是1010、1014和102配置模式，其中模式1010保存的树种为大叶紫薇、簕杜鹃，模式1014保存的树种为凤凰木、黄槐、美丽异木棉，模式102保存的树种为大叶紫薇、凤凰木、红花羊蹄甲、美丽异木棉。

Abstract:

Five sample spots of No.3 and No.10 ecolandscape forest belt in Huicheng District, Huizhou city were investigated through subcompartment survey. The results showed that trees planted in 5 sample spots had a good growth performance, the survival rate was 87.8%, and the average height and diameter at breast height were 2.6 m and 7.5 cm, respectively. The results of comprehensive assessment showed that the order of trees early growth among 5 sample spots was Longfeng > Shuikou > Ruhu > Xiaojinkou > Bailuhu. The ranking of trees early growth of different configuration modes in 5 sample spots indicated that, in No.3 ecolandscape forest belt, top three were 314, 318 and 32, the survival tree species were Delonix regia Cassia surattensis Erythrina cristagalli Cinnamomum camphora in 314, D. regia Cinnamomum camphora in 318 and Lagerstroemia speciosa D. regia Cassia surattensis Cinnamomum camphora in 32, respectively. The top three configuration modes in No.10 ecolandscape forest belt were 1010, 1014 and 102, the survival tree species were L. speciosa Bougainvillea spectabilis in 1010, D. regia Cassia surattensis Chorisia speciosa in 1014 and L. speciosa D. regia Bauhinia blakeana Chorisia speciosa in 102, respectively.
