| 本文通过对广东韶关大宝山矿区及周边地区的实地调查，发现矿区现有植被类型以草丛和灌草丛为主，矿区周边则以自然次生常绿阔叶林、常绿和落叶阔叶混交林、毛竹林及各种人工林等为主；矿区土壤都呈强酸性，各土地类型土壤理化性状普遍偏差，重金属含量普遍偏高；针对矿区的这些植被和土壤特性，本文分别对采矿区、废矿区和排土场等，提出相应的环境整治和植被恢复措施及树种选择，并为保障矿区造林成功率，提出了相应的高强度营林措施。 |

Through the investigation and analysis, the article provided correlative measurements: 1) the dominating vegetation in the mine field was tussock and brushwood, while around the mine field there were distributing abundant natural secondary evergreen broad-leaved forest, evergreen and deciduous broad-leaved mixed forest, phyllostachys pubescens forest and other plantation forests; 2) the soil of the mine district presented not only high-acid, but also poor physicochemical property and high metal content; 3) because of the property of vegetation and soil state some environmental and vegetational restoration measures were putted forward about the mining district, abandoned mine district and refuse-dump.
