| 摘 要： | 本文详细分析了山西辛安岩溶泉的水文地质条件,并通过对泉域岩溶水的补给、径流、排泄条件的分析,将辛安泉域概化为单输入单输出线性时不变集中参数随机系统的概念模型。利用24年的水文序列资料进行基流分割,获得泉多年月平均流量过程曲线,求得泉年平均流量和年平均补给量。在此基础上,应用滑动平均模型(MA),自回归—滑动平均模型(AR-MA)及泉流量调和分析—残差自回归等三个模型,对泉域地下水进行模拟,获得了满意的结果,不仅揭示了泉水动态特征,而且对泉流量动态进行了预报,为晋东南区域经济规划提供了有益资料。

| Abstract: | The Xin karstic spring is the largest spring in southeastern Shanxi. Its average annual discharge is 11.9 cu. m/sec, and the water quality is excellent. Because of the serious shortage of water resource in Shanxi, investigation of this spring is to be of great significance.
In this paper, based on the analysis of the hydrogeological conditions of the spring basin, a hydrogeological conceptual model linear, time invariant withsingle input and single output system-are presented. By using the principle of system theory and stochastic hydrology, the spring discharge is forecasted and the accretiooary groundwater resource is calculated as well, The modelling results are rery compatible with the observed data.
The models presented in this paper are applicable especially to the large spring basin where the longer observed data are available and spring appears to be concentrated. |
