本文在系统分析江汉平原水文地质条件的基础上，将研究区主要含水层划分为三层，由上到下依次为：浅层[Q_4]孔隙潜水含水层、上部[Q_(2+3)]孔隙承压含水层和下部[Q_1+N]裂隙孔隙承压含水层。

Jianghan plain, located in the middle-south of Hubei province. Its ground water resources degree of development and utilization are high. The primary exploitation layers are the upside pore confined aquifer and the underpart cranny and pore confined aquifer. With the rapidly development of urbanization and economic,the water consumption is increasing.That have coused the local ground water table decent.In someplace,the excessive exploitation have induced the groundwater table fall and collapse.

江汉平原位于湖北省中南部，其地下水资源开发利用程度较高，主要开采的为上部[Q_(2+3)]孔隙承压含水层和下部[Q_1+N]裂隙孔隙承压含水层中的水，随着区内城市化建设和经济的迅速发展，用水量增加，区域地下水位已有一定幅度的下降，局部地区因过量开采已形成地下水降落漏斗和地面塌陷等现象。

Results During the period of 1992 to 2004, a number of 41 acute sulfureted hydrogen poisonings occurred in Shanghai with 132 workers poisoned and 46 workers died (34.8%); acute sulfureted hydrogen poisoning showed an increasing tendency, which mostly occurred during the work of sewage pipe dredging in the city planning projects; 68.3% of acute sulfureted hydrogen poisonings occurred in the confined spaces, which was 2.2 times of that in the non-confined spaces.

In other model calculations, the quarks are assumed to be always confined separately in two distinct baryons. The real situation is quite possibly neither completely merged nor always separately confined, but, rather, in between, i. e., partially deconfined due to the interaction of two baryons.

For each strategy, a corresponding exploitation plan of groundwater was designed. Then each designed exploitation plan (except scheme 3) was put into the model for calculation and simulation. The analysis on the forecasting results every plan indicates that:(1) Shuting down the self-provided wells is the most direct and effective method, playing an important role in the land subsidence prevention.(2) The resumption of compressed soil by groundwater artificial recharge is limited. So the artificial recharge can\'t provide essential effect for the resumption of land subsidence, unless the artificial recharge is much more than the groundwater withdrawal.(3) The method of "adjusting the exploitation stratum of groundwater to the shallow" has an obvious effect on the land subsidence prevention.(4)"Sand wells" can increase the leakage recharge for confined aquifer, and thus can slow and prevent the development of the land subsidence.(5) For the groundwater exploitation in Xi\'an, emergency self-provided wells should be managed according to the well spacing of 1600m, 2000m and 1600m, respectively, in the river terrace area, alluvial-proluvial fan area and loess tableland area to exploit the first confined groundwater. Corresponding individual well yield can be set as 2500m~3/d, 1500 m~3/d and 200 m~3/d. Make emergency self-provided wells pump in the dry year and stop pumping groundwater to restore and conserve underground water sources in average years and wet years. In this way, groundwater withdrawal of 162000m~3/d can be obtained to provide for the supplement of water supply in Xi\'an. As a result, the water supply stress can be released in dry years. The groundwater depression formed in the exploiting year can resume in 3-4 years. At the same time, this exploitation manner will not lead to obvious land subsidence.

本文利用所建的模型预测了现状开采条件下未来20年的地下水位和地面沉降的变化，在此基础上，提出了防治西安市地面沉降的五个地下水开采方案，利用所建的地面沉降模型对各个设计方案其进行了模拟和预报，对预测结果的分析表明：①封停自备井是防治地面沉降最为直接和最有效的对策，对防治地面沉降起着最为积极的作用；②采用人工回灌方法使被压缩的土层得到的恢复是非常有限的，对地面沉降不能起到根治作用，只有回灌量明显大于开采量时才能有一定的效果；③&调整开采层次，在浅层取水&对防治地面沉降的效果十分明显；④布设&砂井&可以增加对承压含水层的越流补给量，从而可以有效地缓解和控制地面沉降的发生和发展；⑤对西安市的地下水开采，可在河流阶地区、冲洪积扇区和黄土塬区分别采用1600m、2000m、1600m的井间距布置应急自备井，分别采用2500m~3/d、1500 m~3/d和200 m~3/d的单井开采量，开采第一承压水，在平水年或者丰水年不开采，涵养地下水源，在枯水年启动这些应急自备井开采，在输出分析范围内共可获得162000 m~3/d(5913万m~3/a)开采量，可以有效地补充西安市的供水水源，缓解供水紧张局面，开采年开采导致的下降的水位可在停采3～4年后得到基本恢复，同时，这种开采方式不会造成大的地面沉降量。
