川中丘陵区优良适宜树种选择

Selection of the Excellent and Suitable Tree Species in the Hilly Regions of Middle Sichuan

  • 摘要: 首先选用生长适宜性指标、抗逆性指标、生态功能指标作为控制层,生长周期、更新能力、生长速度、抗旱性、抗寒性、耐瘠薄性、冠层疏透性和根系特性等8个因子作指标层,用层次分析法对柏木、马尾松、桤木和香樟等20个供选树种进行模型选择,然后对得分较高的树种分别在川中丘陵区的柏木纯林、马尾松纯林、松柏混交林中进行改造后的栽培对比试验。结果表明:(1)模型筛选出适宜川中丘陵区的乔木树种分别为麻栎、栓皮栎,刺槐,桤木,喜树,香椿,马尾松、香樟、柏木9个,灌木树种为马桑,黄荆,火棘3个。(2)从成活率、保存率和生长状况分析,香樟、桤木、喜树、窄冠刺槐、香椿均可用于在柏木纯林中补植,立地条件较好的地块以补植香椿为宜,立地条件差的林分中以补植窄冠刺槐为宜。马尾松纯林中应补植香樟和栓皮栎,但补植香樟时应选择土层较厚,土壤含水量较高的林分。补植的苗木以2a生大苗为宜。

     

    Abstract: Firstly,analytic hierarchy process (ahp) was used for 20 selected tree species to conduct model choice,and then tree species of higher scores were used in the tree planting comparison test. The results showed that (1) after being selected by AHP model, the suitable tree species for mid-sichuan hilly regions were German oak,Cork oak, Robinia pseudoacacia,Alnus cremastogyne,Camptotheca acuminata,Cedrela sinensis,Masson pine,Cinnamomum camphora and Cupressusfunebris;while the suitable shrub species were Coriaria sinica,Vitex trifolia and Pyracantha fortuneana. (2)Analyzing from survival rate,preserving rate and growth condition, Cinnamomum camphora, Alnus cremastogyne, Camptotheca acuminata, Robinia pseudoacacia and Cedrela sinensis could be replanted in Cupressus funebris forest site conditions. Cedrela sinensis should be replanted in better site conditions, while Robinia pseudoacacia should be replanted in worse site conditions. Cinnamomum camphora and Quercus variabilis should be replanted in Pinus massoniana forest. But replanting Cinnamomum camphora should be done in the stand with thicker soil layer and higher soil water content. Two years old seedlings of all nursery were suitable for replanting.
