矿区废弃地生态脆弱性评价分析--以个旧锡矿区为例

摘要

The wasteland in the Gejiu Tine Mine was selected for the study in this paper .The representative sampling lands were selected from the two aspects that are the forming causes and different jamming patterns .Then the index factors reflecting the fragility of the wasteland in mine area were chosen from the sampling lands for the analysis and determination.After the analysis, the evaluation system for the eco -environment fragility degrees in the wasteland of mining area were quantitatively constructed for the evaluation and classification of the fragility degrees of the waste -lands.The brief analysis was made in accordance with the changes of the fragility degrees in the research area .%以个旧锡矿区的废弃地作为研究对象，从废弃地的形成原因和不同干扰模式等两个方面选择具有代表性样地，再从样地中选择能反映矿区废弃地脆弱性的指标因子进行分析测定，经分析量化构建了矿区废弃地生态环境脆弱性的等级评价体系，并应用其对废弃地进行脆弱性评价分级，针对研究区的脆弱度变化情况作简要的分析。
