在简述区域水文地质条件的基础上,依据1986～2007年泉水流量系列观测资料,详细论述了区内下降泉、上升泉的年内和多年动态变化特征,对比分析了1967年、1984年、2006年测区各泉域泉水量和泉水总量的时空分布规律和变化特征。利用已有的潜水二维流水量数学模型,推递并建立了利用泉点周围节点水头(水位)预报泉水流量的数学模型,并对测区泉水总量未来15年的变化趋势进行了预报。结果表明,在现状节水灌溉条件下,由于出山径流量的增加和地下水开采量的减少,未来黑河干流中游地区的泉水资源基本处于稳定状态。
Based on the brief description of regional hydrogeological conditions and based on a series of observation data of spring water flow from 1986 to 2007, the characteristics of the dynamic changes of the downward and upward springs in the area during the year and years are analyzed in detail. The characteristics of dynamic changes in the years of 1967, 1984, 2006 Spatial and Temporal Distribution Regularities and Variations of Spring Water Volume and Spring Total Water Volume in Various Spring Regions. Based on the mathematical model of two-dimensional flow of submersibles, a mathematical model for predicting the flow of spring water using the head (node) of the nodes around the springs was deduced and established. The forecast trend of total spring water volume in the next 15 years was predicted. The results show that under the current water-saving irrigation conditions, spring water resources in the middle reaches of the mainstream of the Heihe River are basically stable in the future due to the increase of mountain runoff and the reduction of groundwater exploitation.
