摘    要:对德兴铜矿1号尾矿库库面纯尾砂立地植被恢复与重建进行了研究。结果表明:纯尾砂植被恢复与重建的主要是土壤因子,即土壤组成、结构、水分、养分和毒性。矿区自然植被的次生演替序列为:次生裸地→草丛→灌丛→针叶林→常绿与落叶阔叶混交林、针阔叶混交林→常绿阔叶林6个阶段。纯尾砂立地13种试验先锋草种的优劣热比较结果依次顺序为:水蜡烛1.06>假俭草1.05>苇状羊茅1.01>芒草1.00=弯叶画眉草1.00>狗牙根0.98=百喜草0.98=香根草0.98>象草0.87>荩草0.85>矮象草0.74>节节草0.73>苏丹草0.55。水蜡烛、假俭草、苇状羊茅、芒草、弯叶画眉草、狗牙根、百喜草、香根草、象草、荩草、矮象草、节节草被认为是纯尾砂植被恢复与重建的优良先锋草种。纯尾砂立地植被恢复与重建的途径主要包括植被恢复演替、土壤生物改良和客土复垦3种模式。

关 键 词:德兴铜矿  纯尾砂  植被恢复  先锋草种  演替  矿山废弃地  复垦  植被重建

Abstract:Re\|vegetation in mining wasteland is a principal part of the eco\|environment construction,and an important guarantee of sustainable development in mining areas.This research took the re\|vegetation of No.1 tailing dam in Dexing Copper Mine as an example.Through the analysis of the site environmental condition and the survey of natural vegetation types in the area,the selection of suitable pioneer plant species,and the experiments of artificial re\|vegetation in the tailing sand,the following preliminary r...
Keywords:Dexing Copper Mine  pure tailing sand  re\|vegetation  pioneer grass species  succession
