摘要
利用GMS(Groundwater modeling system)软件建立了鄂尔多斯市浩勒报吉水源地的地下水流数值模拟模型,评价了多年平均条件下的地下水补给资源量,对水源地规划开采方案下的地下水位动态变化进行了预测,并分析了水源地开采条件下可能引起的环境问题。结果表明,在规划开采方案下,预测期内水源地的地下水位降深在允许范围内,预测末水位达到稳定。水源地的大规模开采,会对生态造成一定破坏,但同时也会使低洼地带盐渍化现象得到改善。
Groundwater flow numerical model of Haolebaoji source field in Ordos City was built with GMS （Groundwater modeling system） software. Based on this model, the amount of multi-year average groundwater recharge resources was evaluated and the dynamic of groundwater level was predicted under the planning exploitation plans. What＇s more, the environmental geological problems may arise under exploitation was also analyzed. Results show that, under designed exploitation plan, water level drawdown was lower than allowable during prediction period and water level trends stable at the end of prediction. Large-scale exploitation of source field would cause some ecological damages, but the phenomenon of salinization of low-lying areas will be improved.
