植被覆盖区1∶5万多光谱遥感找矿模式的研究——以内蒙古额尔古纳市大梁研究区为例

INVESTIGATION OF 1∶50000 MULTISPECTRAL REMOTE SENSING PROSPECTING MODEL IN THE VEGETATION COVERING REGION-DALIANG PROSPECTING AREA AT ERGUNA OF INNER MONGOLIA AS A EXAMPLE

地面植被的发育,在一定程度上,弱化、掩盖或屏蔽了岩石和土壤的光谱和空间信息。另一方面,植物的群落、分布和生长状态与下伏岩石土壤特性和构造之间常表现出具有一定的相关性,植被的毒化往往指示矿化的可能存在,植被空间分布和地貌影像特征揭示了构造的展布特征。构造分析和毒化植被的识别是植被发育区1∶5万多光谱遥感地质找矿预测的最佳模式。

Spectrum and space information of rocks and soils can be reduced, covered or shielded by growth of ground vegetation to a certain degree. On other side, biotope, distribution and growth of vegetation have some relations with underlying rocks, soils and structures. Poisoning vegetation might indicate possibility of mineralization. Space distribution of vegetation and topographic image imply structure distributing. Structure analyzing and poisoning vegetation identification are the best prospecting models in the vegetation covering region using muhispectral remote sensing.
