覆盖

Using Landsat TM data, based on the spectral character analysis of main land-use types, different feature models under strong land disturbance in Antaibao opencast coal mine were set up. Vegetation higher cover area, vegetation lower cover area, denudation and cumuli area, excavation and transport area and slope area in Antaibao were extracted. The information of areas with higher vegetation cover and lower vegetation cover were detected by NDVI (normalized difference vegetation index).

该研究利用Landsat TM数据，以安太堡大型露天煤矿为例，在对地物光谱特征深入分析的基础上，设计了大型露天矿区土地剧烈扰动下不同地物特征提取模型，提取了安太堡露天矿区植被高覆盖区、植被低覆盖区、剥离堆垫区、采煤运煤区及边坡区等不同地物信息。
