安徽凤阳县邬岗石英砂尾矿场植被调查

Investigation on the Vegetation in Quartz Tailing Wasteland in Wugang,Fengyang,Anhui Province

通过野外实地调查,采用样方法,调查了凤阳县邬岗石英砂尾矿废弃地的植被自然恢复情况。发现该废弃地自然定居植物共43种,隶属于14科36属,主要包括禾本科、菊科、豆科等。全部自然定居植物中,一、二年生草本植物23种,多年生草本植物17种,木本植物3种。形成了4种相对稳定的演替群落,且群落物种单一,结构简单。矿业废弃地土壤养分的贫瘠,自然环境及人为因素对其影响程度是当前植物在其上定居、分布的主要因素。

Using field work, a study was conducted on the vegetations in the quartz tailing wasteland in Wugang, Fengyang, Anhui Province. 43 species in total of natural colonized plant, belonging to 14 families and 36 gene- ra, were found, among which, 23 species were annual plant, 17 species perennial and 3 species bush. Most of the species were belonging to Gramineae, Compositae, and Leguminosae. 4 relatively stable communities were found. The main limiting factors of vegetation distribution were extreme infertility of the wasteland, and degree of natural recolonization.
