| 摘 要： | 水厂铁矿经多年大面积、高强度的开挖, 矿区生态环境不断恶化。地物波谱测试结果表明, 植被波谱曲线普遍发生"红边蓝移, 绿峰降低"的效应, 是典型的铁化合物中毒变异的特征。从工业场地到外围, 植被波谱曲线的红边"蓝移"数值有明显变小的趋势, 表明植被铁化合物中毒现象逐渐减轻。矿山典型地物波谱特征测试和分析是确定各类地物特征谱带或诊断性谱带的重要依据, 是矿山生态环境高光谱遥感调查的理论基础。

| Abstract: | The eco-environment in the Shuichang iron mining area has continuously deteriorated after many years of extensive and substantial mining operations.Surface spectral testing indicates that the spectral curves of vegetation commonly display the phenomenon of "blue shifts of red edges and down shifts of green peaks",which is a typical aberrance character of poisoning of iron compounds. From the operation site to peripheries,the values of red edge "blue shifts" have a trend of decreasing markedly,which indicates that the poisoning symptom of iron compounds is reduced gradually.Testing and analysis of the typical surface spectral features of the mine furnish important evidence for the determination of characteristic spectral bands or diagnostic spectral bands of various surface features and also provide a theoretical basis for the hyperspectral remote sensing survey of the eco-environment of the mine. |
