【Abstract】 The Chaiwobao basin of Xinjiang is a Mesozoic-Cenozoic intermountain basin. It belongs to the Bogeda anticlinorium of the Tianshan geosyncline fold belt. The basin is characterized by abundant ground water, which makes it the major water supply place in Urumqi. The whole outline and structure of the Chaiwobao basin are strictly controlled by tectonics, while terrain and microgeomorphy are mainly controlled by river drainage system. The paper mainly discusses the relationship between neotectonic movement and groundwater. The basin is divided into three hydrogeological regions independently according to neotectonic pattern, in which ground water possesses many features. At the same time, the authors indicate that the rise, uplift and subsidence of the neotectonic fault block have controlled not only the thickness and lithology of Quaternary sediments in Chaiwobao basin, but also the recharge, runoff and drainage of groundwater. The tectonic pattern formed by different tectonic movements is the key to reserve groundwater in abundance at the alluvial edge of the piedmont depression belt, and the groundwater can well permeate, enrich, and lead in the neotectonic fault belt which renders possible important reserving concourse and movement channels of groundwater. The formation and distribution of groundwater, shifting and storage of groundwater, the hydrogeochemical characters as well as their variation are well controlled by the neotectonic movement.更多还原
