摘要 长江流域基础地质遥感调查与监测,采用2000年左右获取的1∶25万Landsat ETM图像进行地貌、第四纪地质和新构造遥感调查与研究
。针对洞庭湖重点区,采用航片、ALOS、SPOT等高分辨率数据进行 1∶5万详细遥感调查。通过调查与综合分析认为: 江汉—洞庭盆地为一燕
山晚期至新生代形成的断陷盆地,总体处于沉降状态,盆地内部因差异抬升作用形成华容次级隆起,从而在山区广泛沉积了河湖相、冲洪积
相及山麓相的第四纪沉积物,盆地内部第四系基本为连续沉积。江汉—洞庭盆地周围隆起区则呈间歇性抬升。新构造运动主要表现为隆起与
拗陷、掀斜和断裂等几种形式,其构造沉降与周边山体隆升主要受盆地边缘和盆地内部断裂的控制。

Abstract: During the geological remote sensing investigation and monitoring of Yangtze River Valley, the authors carried
out the survey and research on geomorphology, Quaternary geology and neotectonic fracture at the 1∶250 000 scale by using
the Landsat ETM images acquired around 2000. Detailed remote sensing investigation at the 1∶50 000 scale was conducted in
an important area of Dongting Lake by using aerial photos, ALOS, SPOT and other high-resolution data. The investigation and
comprehensive analysis show that Jianghan-Dongting Basin is a rift basin formed in late Yanshanian-Cenozoic period. It was
on the whole in the subsidence state because of differential elevation causing the formation of the sub-Huarong uplift in
the interior of the basin, which extensively deposited river lacustrine facies, alluvial facies and foothill facies
Quaternary strata in mountain areas. Quaternary sedimentation within the basin is basically continuous deposition. The
upwelling areas around Jianghan-Dongting basin are characterized by intermittent uplift. Neotectonic movement mainly finds
expression in uplift, depression, tilting and fracturing. The structural subsidence and uplift of the surrounding mountains
are controlled by the fractures on the edge and in the interior of the basin. |
