黄河三角洲生态保护的地下水管理方案研究
首发时间:2007-04-03
摘要:地下水作为生态环境的重要组成部分,具有不可忽视的生态效应。理解和掌握地下水的动态变化规律是在一个地区实行水资源管理和土地利用管理的先决条件。在提出基于保护黄河三角洲生态环境的地下水管理方案基楚上,用MODFLOW对实施方案后地下水水位、地下水流动方向、补给和排泄条件的变化进行了预测。根据模型预测结果,故道输水、减灌排碱、湿地恢复方案的实施可以改善地下水水质、增加淡水补给、降低盐碱化程度,能有效地改善生态环境、提高生物多样性水平。

The groundwater management for Ecology Environment Protection in Yellow River Delta
Abstract:As an important environmental element, groundwater’s ecological affects can not be neglected. Knowledge of groundwater systems is a pre-requisite for up-to-date integrated land and water management. Groundwater-related management measures are brought in this paper such as flooding abundant river course, controlling irrigation and alleviating salinization, wetland artificial recover. The potential situation after implementing the measures is simulated by groundwater model. Changes in groundwater level, flow direction, recharge and discharge amount have been calculated. The results indicates that all measures will make good efforts on local ecological environment and enhance the level of biodiversity.
