遥感技术在安徽省地质灾害调查中的应用研究

APPLICATION OF REMOTE SENSING TECHNIQUE IN THE SURVEY OF GEOLOGICAL DISASTER OF ANHUI PROVINCE

利用遥感资料对安徽省进行地质灾害调查，查明了地质灾害的类型、规模、圈出灾害影响范围，为总结分析灾害发生、发展规律、进行灾害区划，预测灾害易发区段，防灾减灾，提供了科学依据。

The traditional geological disaster survey relies on field reconnaissance with a lot of manpower and expenditure. In the project of “Remote sensing for land resources in Anhui Province”, author uses TM images and tape data to survey the geological disaster for the first time. This method not only extends the limitation of field reconnaissance, but also is more suitable for studying lager scale surface disaster. With which, the quantitative and qualitative study can be used in the geological disaster, so its type, scale and extent can be surveied objectively, accurately and quickly. The result of survey can be utilized to analyze the causes of disaster and how it develops. Also it can be used to make disaster zoning, predict vulnerable area and offer scientific proof for disaster preparedness and relief.
