遥感技术在西北生态脆弱区生态地质勘查中的应用研究

生态地质勘查正在成为煤炭地质勘查工作的主要发展方向。遥感技术作为“非接触式”勘查技术,在生态地质勘查中应有一席之地。通过阐述遥感技术在煤炭、天然气水合物、油页岩等资源勘查中的工作程序及勘查实例,认为在西北生态脆弱区资源勘查领域遥感技术具有独特的优势:通过不同比例尺的遥感煤田地质填图,可快速高效圈定含煤远景区;利用遥感图像的热红外波段数据可以快速获取与水合物相关的温度异常信息,圈定热异常分布区,为天然气水合物进一步勘探指明方向;通过对遥感图像的处理可直接提取与油页岩相关的成矿异常信息,圈定找矿远景区。在西北生态脆弱区应用遥感技术进行资源勘查具有好的经济效益和生态效益。

Application of Remote Sensing on Eco-geological Exploration in Northwest China Ecologically Vulnerable Area

Eco-geological exploration is a main development orientation in coal geological exploration.As a“non-contact type”exploration technology,the remote sensing should have a place in eco-geological exploration.Through expounding of remote sensing procedures and cases in coal,natural gas hydrate,oil shale etc resource exploration have considered the unique advantages of remote sensing in the Northwest China ecologically vulnerable area resources exploration domain.Through different scales remote sensing coal geological mapping,can fast and efficiently delineate coal-bearing prospect areas.Using remote sensing image thermal infrared band data can fast acquire temperature anomalous information related to hydrate,delineate thermal anomalies distribution,and point out further natural gas hydrate exploration orientation.Through remote sensing image processing can directly extract anomalous information related to oil shale ore-forming,delineate prospecting prospects.The application of remote sensing to carry out resource exploration has favorable economic and ecological benefits in Northwest China ecologically vulnerable area.
