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314、318、32,其中模式314保存的造林树种为凤凰木、黄槐、鸡冠刺桐、樟,模式318保存的树种有凤凰木、樟,模式32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1010、1014和102配置模式,其中模式1010保存的树种为大叶紫薇、簕杜鹃,模式1014保存的树种为凤凰木、黄槐、美丽异木棉,模式102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 ecolandscape forest belt in Huicheng District, Huizhou city were investigated through subcompartment 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 ecolandscape forest belt, top three were 314, 318 and 32, the survival tree species were Delonix regia Cassia surattensis Erythrina cristagalli Cinnamomum camphora in 314, D. regia Cinnamomum camphora in 318 and Lagerstroemia speciosa D. regia Cassia surattensis Cinnamomum camphora in 32, respectively. The top three configuration modes in No.10 ecolandscape forest belt were 1010, 1014 and 102, the survival tree species were L. speciosa Bougainvillea spectabilis in 1010, D. regia Cassia surattensis Chorisia speciosa in 1014 and L. speciosa D. regia Bauhinia blakeana Chorisia speciosa in 102, respectively.
