绿洲不同尺度地下水时空动态变化特征及成因分析
Study on the Characteristics and Causes of Temporal-spatial Variation of Groundwater on Different Scales in the Oasis of Qitai,Xinjiang
摘要
Abstract
[Objective]Improperly developing and using the underground water will cause a series of environmentally ecological problem.The scientific theory of the regular change of the underground water provides the important assurance and necessary premise for the effective development and management of the underground water in the arid area in the future.[Method]This paper analyses the characteristics and causes of temporal-spatial variation of groundwater in Qitai oasis on the northern slope of Tianshan Mountains on county and township scales.[Result] Groundwater level changing within the country range is deeply impacted by the factor of the population and the land factor produces a more deeper effect on the arable scale.On township scale,in the towns with a long history of agricultural development in west-east direction,the groundwater level declined rapidly in early period and then gradually slowed down.However,the area mainly developing animal husbandry in early period was the opposite.On south-north direction,the average decline speeds of groundwater level in different areas are in the following sequence:centre(0.47 m/a) ＞north(0.31m/a) ＞ south (0.13 m/a).[Conclusion] Although the most important cause of groundwater level variation is the increase of cultivated area,there are various reasons for the differences of groundwater level from south to north and from west to east on small scale.For the south-north direction,the reason is that the farmland of each township or town is different in position and geomorphology as well as hydrological conditions.For the west-east direction,the reason is that differences in agricultural development degree can cause different increase ratios of cultivated area in different periods.关键词
