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。

Taking a special position in China, the RUC has won the high recognition of the State and Government since its establishment. It was ranked into the national key universities for three times, i.e., in 1954, 1959 and 1960. It was ranked first in the top ten universities China shall build with focus in 1980. Following that the RUC was first listed in the key universities of the "211 Project".

The results show that a the variation of annual mean runoff of Huayuankou section exist an intrinsic dynamic mechanism, which is the results of joint action of affecting factor of periodicity and non-periodicity, having obvious chaos characteristic; b the correlation dimension of attractor of phase space is 5.09 and saturation inserted dimension is 14. It shows that to establish a mathematical model of the annual mean runoff system of Huayuankou at least requires 6 independent variables and the required saturation inserted dimension for rebuilding phase space is 14; c the steady estimate of Kolmogorov entropy is 0.14, showing the average predictable time of the annual mean runoff variation of Huayuankou is about 7 years and; d using nonlinear deterministic chaos model is more suitable to describe the variation of annual mean runoff of Huayuankou.
结果表明:①花园口年平均径流量变化存在着内在动力学机制,是由周期性和非周期性影响因子共同作用的结果,具有明显的混沌特性;②相空间吸引子的关联维为5.09,饱和嵌入维数为14,这说明要建立花园口年平均径流系统的数学模型,至少需要6个独立变量,重构相空间所需要的饱和嵌入维数为14;③Kolmogorov熵的稳定估计为0.14,说明花园口年平均径流量变化的平均可预报时间大约为7年;④用非线性确定性的混沌模型比完全的随机模型更适于描述黄河花园口年平均径流量的变化。
