西双版纳采矿区植被恢复中的树种选择研究

Selection of Tree Species for Vegetation Restoration in Mining Area in Xishuangbanna

为了在西双版纳采矿区植被恢复过程中提供适宜的树种,在景洪市的采矿区中选择了具有代表性的树种20余种,通过3年的栽培研究发现:银合欢、降香黄檀、高阿丁枫等部分树种非常适宜采矿区的立地条件,生长良好,取得了较好的植被恢复效果,这部分树种可在今后的采矿区植被恢复中采用,而羯布罗香、望天树、白木香等一部分树种不适宜这类立地条件,表现出生长不良甚至全部死亡,说明这部分树种不适宜在采矿区的植被恢复中采用。

in order to select suitable plant species for the vegetation restoration in mining area of Xishuangbanna,more than 20 representative tree species were planted in mining area of Jinghong city and their adaptabilities were analyzed based on their growth performance after 3 years. The results showed that some tree species such as Leucaena glauca,Dalbergia odorifera,Altingia excels,etc.,grew very well and thus could be used for the vegetation restoration of mining area in the future. Contrarily,some other tree species such as Dipterocarpus turbinatus,Parashorea chinensis,Aquilaria sinensis,etc.,grew poorly or even died,thus were inappropriate to the site condition of mining area,hence could not be used for the vegetation restoration in mining area.
