| 摘 要： | 中国东部地区古河道广泛分布,古河道发育区的表层岩性纵横向变化较快,表层结构复杂.随着近些年东部地区工农业生产大量抽取地下水,导致近地表的水文系统人为改造严重,局部地区地下水大幅沉降,形成许多地下水漏斗区.同时工农业建设在地表进行了开挖、回填或堆积,进一步加剧了表层结构的复杂性.这种受人为改造的表层结构区对表层调查方法提...

| Abstract: | Paleochannels were widely distributed in the east of China,where rapid changes of surface lithology were induced laterally and surface structure was complex in the paleochannel developed area.In recent years,for the large quantity of underground water pumping for industrial and agricultural usage,hydrologic systems close to land surface have been reconstructed and changed severely.Underground water subsidence was induced locally and resulted in many underground hopper areas.At the same time,in industrial an... |
