中文摘要:

通过对塔里木河下游断流河道2000—2006年8次生态输水期间9个地下水监测断面40口监测井潜水埋深变化监测数据的分析,探讨了生态输水以来潜水埋深变化的规律。结果表明:在8次输水的影响下,潜水埋深总体有显著抬升。运用SPSS统计软件对监测数据进行的回归分析表明,近年来塔里木河下游地区潜水埋深抬升是生态输水作用的直接结果,且抬升幅度与输水持续时间和输水量大小成显著正相关关系,横向和纵向上还表现出潜水埋深抬升幅度随距输水源距离改变而变化的正相关关系。塔里木河下游地区地表水是地下水的主要补给来源,且地表水补给地下水主要是以线型渗漏补给,这是输水以来潜水埋深变化呈现上述规律性的主要原因。输水对潜水埋深的影响具有累积性和滞后性,随着输水的继续进行,潜水埋深变化的规律性会越来越明显。

英文摘要:

The lower reaches of the Tarim River is from Qiara to Taitema Lake and with 428 km in length, also called "Green Corridor". Since 1970s, the watercourse from the Daxihaizi Reservoir has been dried up. Consequently, the vegetation relying on groundwater in this region almost dies out, the forests of Populus euphratica are degenerated in the large areas, wind erosion and land desertification become more serious, the ecosystems are seri- ously damaged. In order to save the "Green corridor", the emergency ecological water transport project in the lower reaches of the Tarim River was carried out from July, 2000, and the water reached Taitema Lake finally. After six years emergency ecological water transport, the situation in the lower reaches of the Tarim River has a great change. The regulations of variation in risen amplitude of the groundwater level after ecological water transport in the lower reaches of the Tarim River are analyzed based on the monitored data of the eight times of stream water conveyance to the river section where the stream flow has been cut-off for more than 30 years and of the nine groundwater-monitoring sections and forty monitoring wells in the lower reaches of the Tarim River from 2000 to 2006. The results show that the groundwater level of the groundwater-monitoring sections has been lifted obviously since eight times' stream water conveyance. Statistical analysis on the variation of risen amplitude of the groundwater level by regression analysis method with sPss 13.0 reveals that the lifting of the groundwater level is closely related to the ecological water transport in the lower reaches of the Tarim River and there is positive correlation between the risen amplitude and the duration and quantity of the ecological water transport. The surface water is the main supply source of groundwater in the form of linear leakage in the lower reaches of the Tarim River. This is the main reason why the regularity of variation in risen amplitude of the groundwater level is related with eco
