西安地下水位埋深变化分析及预测

Analysis and Forecast to Water Depth Changes of Xi'an in Recent Years

基于对近年来西安地区各地貌单元潜水和西安市区承压水埋深的分析,采用不同的模型,对水位埋深的变化情况进行了预测检验。并依据降水量和水文地质的分析,提出降水量和水位埋深相互照应的关系,地下水补给量减少的状况,可能对水位埋深变化产生的影响。结果预测,到2010年,西安地区各地貌单元潜水平均埋深将超过16.9m,2006年,2008年市区的承压水位埋深可能分别达到94.1,90.2。讨论认为持续的水位下降将可能导致严重的后果。解决水位埋深变化带来的问题需要长期的研究和努力。

Based on analysis to the geomorphic units of diving water and confined water in in Xi＇an area, using different models, examined the prediction in the changes of depths in water level. At the same time, based on analysis of precipitation and hydro--geological, it puts forward the relationship on taking care each other in precipitation and the situation of reducing groundwater recharged quantity, may bring some impact on water depth. The results predict the average depths to the water of different physiognomic units in the Xi＇an area will be more than 16.9m in the year of 2010. The depth of confined water level may reach 94. 1m,90.2m separately in 2006 and 2008. After the above discussion, think that the continuing decline in water level may lead to serious consequences in Xi＇an. It will take a Long--term research and efforts to solve the water depth of the problems.
