摘要
对广西荔浦锰矿废弃地植被进行了调查研究。共记录了高等植物71种,隶属38个科。优势种包括板栗、老虎刺、桉树、马唐、加拿大飞蓬、山萝花、赛葵等7种植物。由于受人为干扰,整个矿区形成了七个不同植被特征的区域。通过对七个区域的植被特征分别进行了分析,推测出荔浦锰矿废弃地在植被重建过程中的植被动态,认为马唐、加拿大飞蓬可作为复垦的先锋植物;板栗×老虎刺是该区较好的人工植被重建模式。
Vegetation in mining waste land of Lipu Manganese Mine was studied with field survey. 71 species belonging to 38 families were found growing in the mining waste land, including 7 dominate species： Castanea henryi, Pterolobium punctatum, Eucalyptus robusta,Digitaria sanguinalis, Erigeron canadensis, Malvastrum coromandelinum and Melampyrum esquirolii. Due to anthropic disturbance, seven samples with different vegetation characters were compartm - entalized in the mining area. By analyzing the characters of vegetation of the samples, succession directions of artificial revegetation were deduced. The results show that Digitaria sanguinalis and Erigeron canadensis are adaptive pioneer species and Castanea henryi and Pterolobium punctatum is a successful model of artificial revegetation of the mining waste land.
