摘要
为了摸清新乡市傍河水源地浅层地下水资源状况,对浅层地下水资源总量进行了计算和分析。结果表明,利用均衡法计算得出现状年浅层地下水总补给量为13 289.85万m3/a,排泄量为13 260.05万m3/a,均衡差为29.8万m3/a。各均衡区计算水位与实测水位亦比较接近,表明计算所选参数比较合理,计算的补给量和排泄量可靠;采用均衡法、解析法和数值法对设计新增的地下水允许开采量35万m3/d进行了评价,结果表明本次评价的水源地地下水允许开采量的补给量是有保证的;水源地内浅层地下水水质较好,经适当处理后适宜饮用;通过建立水源地保护区和水源地开采监测来保证饮用水的水质安全。
To find out the status of shallow groundwater resources of the riverside water sources area in Xinxiang city,the total shallow groundwater resources are calculated and analyzed in this paper.The calculation results of equilibrium balance method show that the total shallow groundwater resources is 132.898 5million m3 per year,the excretion quantity is 132.600 5million m3 per year,the balance difference is 0.298 million m3 per year;the calculated water level is also close to the measured water level for each equilibrium balance region,indicating that the selected calculation parameters are reasonable,the calculated recharge and excretion quantity is reliable;the balance method,analytical and numerical methods are adopted to evaluate the new added groundwater allowable withdrawal quantity of 0.35 million m3 per year.The evaluation results show that the replenishment quantity for the added groundwater allowable exploitation quantity is assured;shallow groundwater quality within the water source is good and suitable for drinking after appropriate treatment;the water quality safety can be ensured through establishing water source protection areas and monitoring mining water quality.
