摘　　要：植被覆盖区遥感地质信息提取一直是国内外遥感地质领域的研究重点之一。介绍了利用间接证据链,通过追溯植被冠层温度-气孔阻力-植物水势-根系实际吸水-土壤供水-土壤水分含量,最终以土壤水分含量异常与断裂构造表观特征建立联系。使用TVDI、PDI、MPDI、SPSI遥感土壤水分反演模型提取福建大小矾山地区植被覆盖下的断裂构造信息。Geological information extraction by remote sens,ng in vegetation-covered areas was one of the research priorities in the fields of remote sensing geology. The authors introduced the use of evidence chain combined with geological structure information and remote sensing information. By monitoring the evidence chain of plant canopy temperature- stomatal resistance- plant water potential-ac- tual root water uptake-soil water supply-soil water content, the underlying soil humidity would be indirectly acquired from the apparent plant canopy temperature, which finally reflected the moisture abnormal of fracture structure areas. Finally, using the soil humidity in- version modes such as TVDI,PDI.MPDI and SPSI, the authors highlighted the fracture structure information under the vegetation-cov- ered areas in the Wuyi Mountains of Fujian Province.
