南亚热带次生林主要树种早期生长表现

Early Growth of Main Tree Species in Secondary Forests of South Asia Tropics

为全面改善次生林森林质量,调整功能性群落结构,提升物种多样性,在广州市石门国家森林公园石灶工区开展南亚热带次生林恢复研究。试验设置了5块40 m×40 m样方,采用组内随机混交的方式种植,补植10种南亚热带次生林主要造林树种,半年后观测其生长表现。结果表明:在次生林补植半年后,浙江润楠Machilus chekiangensis、桢楠Phoebe zhennan、闽楠Phoebe bournei、南方红豆杉Taxus wallichiana等9个引入树种的成活率高于红锥Castanopsis hystrix。

In order to comprehensively improve the quality of secondary forests,adjust the functional community structure,and enhance species diversity,a study on the restoration of South Asian tropical secondary forests was conducted in the Shizao work area of Shimen National Forest Park in Guangzhou.In this experiment,five plots of 40 m×40 m quadrats were set up,and 10 main afforestation tree species in the south subtropical secondary forest were replanted by random mixing in the group,and their growth performance was observed after half a year.The results showed that the survival rate of 9 introduced tree species such as Machilus chekiangensis,Phoebe zhennan,Phoebe bournei,Taxus wallichiana was higher than that of Castanopsis hystrix after replanting for half a year.
