摘要
采用佳木斯市区2001～2005年的地下水观测资料,对城区地下水的动态变化、影响因素及降落漏斗的现状与发展进行分析。结果表明,"十五"期间,佳木斯市城区地下水位埋深范围为6.64～10.85m,水位标高范围为70.92～74.66m。由于大气降水具有迟后补给作用,2001年降水量最小,为350.5mm,造成2002年地下水位最低;2003年降水量最大,为564.4mm,使得2004年水位最高。地下水的常年大量开采,使城区已形成约60km2的降落漏斗,并向南侧和东北侧略有扩展。
Using 2001-2005 groundwater information to analyze the groundwater actuality and development of Jiamusi city. The results show that the buried depth of groundwater levels varied between 6.64 and 10.85 m, and groundwater elevation ranged from 70.92 to 74.66 m. Due to the function of delayed atmospheric precipitation recharge, the rainfall was minimum in 2001, 350.5 mm, but the groundwater level was the lowest in 2002; and the rainfall achieved to maximum in 2003, 564.4 mm, but the groundwater level reached to peak in 2004. In the city zone, the land-surface subsidence caused by groundwater overexploitation was about 60 km^2, and it extended to south and northeast directions slightly.
