粤西东山森林公园主要造林树种选择与经营模式

以云浮市东山森林公园14种主要造林树种为研究对象,采用套种补植、人工造林2种造林方式和穴状抚育或全面割灌+穴状抚育的抚育方式组合,分析4种经营模式下14种阔叶树种的生长情况.结果表明:采用相同的造林方式时,各树种在全面割灌+穴状抚育的抚育方式下胸径生长较好,但对树高的生长影响不显著;采用相同的抚育方式时,采用套种补植造林的樟树(Cinnamomum camphora)、木荷(Schima superba)、铁冬青(Ilex rotunda)、红苞木(Rhodoleia championii)、秋枫(Bischofia javanica)和米老排(Mytilaria laosensis)胸径和树高生长大于人工造林的,黄槐(Cassia surattensis)、降香黄檀(Dalbergia odorifera)和羊蹄甲(Bauhinia purpurea)人工造林的胸径和树高生长大于套种补植的;云浮市东山森林公园建设的适宜基调树种为米老排、火力楠(Michelia macclurei)、木荷(Schima superba)、樟树、秋枫和降香黄檀,主题树种为铁冬青、黄槐、大叶紫薇(Lagetstroemia speciosa)和美丽异木棉(Ceiba speciosa),以及应用套种补植结合全面割灌+穴状抚育的经营模式.

Analysis on the selection and management pattern of main afforestation tree species in Dongshan Forest Park of the West Guangdong Province

The research aimed at analyzing the growth of broad leaved tree species under different afforestation methods(interplanting replanting and artificial afforestation)and management models(cave tending and overall shrub cutting+cave tending). 14 afforestation tree species in Yunfu Dongshan forest park were selected as the research objects. The results showed that all species'ground diameters growth were better under the overall shrub cutting+cave tending while effect on the growth of tree height was not significant under the same afforestation management. Using the same way of tending, the ground diameter growth and tree height growth of Cinnamomum camphora, Schima superba, Ilex rotunda, Rhodoleia championii, Bischofia javanica and Mytilaria laosensis under intercropping planting were better than the growth under artificial afforestation; Cassia surattensis, Dalbergia odorifera and Bauhinia purpurea were opposite. In genenal, Mytilaria laosensis, Michelia macclurei, S. superba, Cinnamomum camphora, Bischofia javanica and Dalbergia odorifera were suitable to use as key species and I. rotunda , Cassia surattensis, Lagetstroemia speciosa and Ceiba speciosa were suitable to use as theme species on the construction of Yunfu Dongshan forest park. In addition, intercropping planting and overall shrub cutting+cave tending is the better management models in the study.
