| 摘 要： | 在阐述银川平原浅层地下水形成分布规律性的基础,首次在该地区采用三维地下水有限差分模型计算了地下水资源量、补排组构和可利用量。论证和提出用有害盐量取代以往惯用全盐量评价盐害和计算排引比的传统做法,通过水盐均衡计算指出30多年来灌区——直处在脱盐状态。论证和提出了银北灌区各类水量的宏观调控意见,动态模拟计算了不同规划水平年引、排水9套方案,提出了不同地区和采用不同方案引用黄河水量和开发利用地下水量的意见。

| Abstract: | On the basis of clarifying the laws of shallow groundwater formation and distribution, the 3-D finite definite model is firstly employed to calculate the volume of groundwater resources, recharge and discharge structure and available amount of water. The traditional means of evaluating salt damage and calculating drainage-division ratio with total salt are argued and replaced by the method of harmful salt. Through water salinity balance calculation, it is revealed that the irrigated area has been in a desalinization status in the past 30 years. The idea of regional water amount control in Yinchuan irrigated area is put forward. Nine division/drainage alternatives for different planning years are simulated. Suggestions concerning Yellow River diversion amount and groundwater exploitation in different areas with different alternatives are given. |
