摘　　要：在已有研究区水文地质资料的基础上,进行基于ASTER数据的岩溶地下水天然出露点信息的提取与识别。根据研究目标,以ASTER数据为信息源和调查工具,制定相应的图像处理和分析流程,增强与岩溶地下水天然出露点信息相关的影像特征;应用热红外遥感理论和技术,以ASTER数据热红外波段为信息源,借助岩溶地下水天然出露点与其他地物的温度差异,探索它们之间的可分性;结合ASTER数据可见光/近红外、短波红外波段的解译成果,进行岩溶地下水天然出露点信息识别。On the basis of the existing hydrogeological data in the study area,extraction and recognition of information on natural outcropping points of the karst groundwater system based on ASTER data are carried out.According to the research target and taking the ASTER data as information source and investigation tools,the corresponding image processing and analysis process are formulated,and the related video features of the information on the natural outcropping points of the karst groundwater system are enhanced.With the ASTER data thermal infrared bands for information source,thermal infrared remote sensing theory and technology are applied,and the difference in temperature between the outcropping points of the natural karstic groundwater system and the features of other objects is taken into account.The separability between them is also explored.Combined with the ASTER data of near infrared and visible/shortwave infrared bands,information on the natural outcropping points of the karstic groundwater system is identified.
