【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 base of hydro -geological conditions describing and summarizing,with the help of 1986 -2007 observed dada on spring water current capacity,this paper was presented to elaborate annual and inter - annual dynamic change characteristics of descending springs and ascending springs in this region in detail,the contrastive analysis method was used to describe the temporal - spatial distribution regularities and change features of 1967, 1984 and 2006’s spring water volume and their total volume of each spring area Using the existing two - dimension ’s mathematical model for groundwater flow,a mathematical model was researched and put forward,which could be used to forecast the spring flow volume according to spring periphery node flood peak(water level),and to carry out the forecast of changing tendency of next 15 -year’s spring total volume.The result indicated that under the condition of saving water irrigation at the present,the spring water resources will be at the steady state basically,because of the amount increasing in the stream flow from the mountains and the decreasing in groundwater exploitation.更多还原
