【摘要】：為定量分析降水、徑流和開(kāi)采對(duì)西安地區(qū)潛水流場(chǎng)影響程度,應(yīng)用小波變換、最小二乘相關(guān)分析等研究方法,對(duì)區(qū)域平均地下水位,水源地漏斗中心水位及漏斗面積與降水、徑流和開(kāi)采變化之間的特征進(jìn)行了研究。結(jié)果表明:1986—2010年期間,平均地下水位隨降水量的增大呈線性函數(shù)遞增趨勢(shì),降水量每增加100 mm,平均水位上升0.77 m,漏斗中心水位變化速率隨降水量的增大呈直線下降趨勢(shì),年均降水量每增加100 mm,漏斗中心水位上升0.7 m(灞河水源地)、0.27 m(灃皂河水源地)和0.14 m(渭濱水源地);1986—2010年期間,徑流量每增加1×10~8m~3,區(qū)域平均水位上升0.9~1.98 m,漏斗中心水位上升0.32~2.36 m,漏斗面積減小0.019~13.2 km2;1998—2010年期間,地下水開(kāi)采量每增加0.1×10~8m~3,區(qū)域平均水位降幅達(dá)1.14~5.37 m,水源地漏斗中心水位降幅0.94~5.76 m,漏斗面積擴(kuò)大0.44~27 km2;關(guān)聯(lián)度分析表明,降水、開(kāi)采是西安地區(qū)潛水流場(chǎng)變異的主導(dǎo)因素。
[Abstract]:In order to quantitatively analyze the influence of precipitation, runoff and mining on the groundwater flow field in Xi'an area, the research methods of wavelet transform and least square correlation analysis are used to study the regional average groundwater level, the central water level and the funnel area of the funnel in the source area and the precipitation. The characteristics between runoff and mining changes were studied. The results show that the average groundwater level increases linearly with the increase of precipitation during 1986-2010. The average water level increases by 0.77 m for every 100 mm of precipitation, and the variation rate of central water level of funnel decreases linearly with the increase of precipitation. For every 100 mm annual precipitation, the central water level of the funnel rises by 0.7 m (Bahe water source) 0.27 m (Fengzaohe water source) and 0.14 m (Weibin water source) during the period 1986-2010. For every 1 脳 10 ~ (-1) m ~ (-1) increase of runoff, the regional average water level rises by 0.9 ~ 1.98 m, the central water level of funnel increases by 0.32 ~ 2.36 m, and the area of funnel decreases by 0.019 ~ (13. 2) km ~ (2) ~ (2) during the period 1998-2010. For every 0.1 脳 10 ~ (8) m ~ (3) increase of groundwater exploitation, the regional average water level decreases by 1.14 ~ 5.37 m, the central water level of the funnel decreases by 0.944 ~ 5.76 m, and the funnel area is increased by 0.44 ~ (27) km ~ (2). The correlation analysis shows that precipitation and exploitation are the leading factors for variation of groundwater flow field in Xi'an area.
