1 水资源开发利用及降落漏斗发展情况随着经济、社会的迅速发展,三门峡市区人口不断增加,工业产值持续增长,年用水量从1964年的180万m~3增至1999年的2636万m~3,预测到2010年需水量将达到7000万m~3,需水量与日俱增,供需矛盾日益突出。三门峡市市区地下水资源量2235万m~3,可开采量为1726万m~3。1995年以前,三门峡市供水全部由地下水供给,年开采量2561万m~3,大量超采地下水,造成地下水位持续下降,到1996年降落漏斗已由1989年的25km~2扩大到33.2km~2,降落漏斗中心水位标高最低为
1 Development and Utilization of Water Resources and Development of Landing Funnel With the rapid economic and social development, the population of Sanmenxia urban area continues to increase and the industrial output value continues to grow. The annual water consumption has increased from 1.8 million m3 in 1964 to 26.36 million in 1999 It is predicted that water demand will reach 70 million m ~ 3 by 2010, water demand will increase day by day, and the contradiction between supply and demand will become increasingly prominent. Sanmenxia City groundwater resources 22350000 m ~ 3, recoverable amount of 17260000 m ~ 3. Before 1995, Sanmenxia city water supply by the groundwater supply, the annual exploitation of 25610000 m ~ 3, a large number of over-exploitation of groundwater, resulting in The groundwater level continued to drop. By 1996, the size of the funnel dropped from 25km 2 to 33.2km 2 in 1989. The lowest water mark in the center of the funnel fell to
