【摘要】 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。更多还原

【Abstract】 On the basis of 1986-2007 year spring water current capacity series observed data,the paper in-troduced hydro-geological conditions in the region,elaborated the descending spring,the ascending spring of the region single year and multi-year dynamic change characteristics in detail,and provided the contrastive analysis measured area various quantities of spring water total quantity space and time distribution rule and the change characteristic in 1967,1984,2006.Using the existing diving two-dimensional current capacity mathematical model,then pilling hands over and establishing the mathematical model of using spring periphery node flood peak(water level) to forecast the spring water current capacity,and to measure that the area spring water total quantity 15 year change tendency has carried on the forecast in the future.The result indicated that the spring water re-sources will be at the steady state basically in the future the middle reaches of Heihe River trunk stream area under present situation saving water irrigation condition,because the amount increase of the stream flow flowing from the mountains and the groundwater exploitation decreasing.更多还原
