摘　　要：焦作矿区岩溶水在闭矿和城市减采双向因素影响下,水位如何变化是焦作城市建设非常关注的问题。运用斜率灰色关联度分析法,研究了水位与降水量、开采量之间的关联程度。采用滑动平均法与Mann-Kendall非参数统计法,分析了1965年以来的岩溶水位、降水量和开采量的变化趋势,并在分析岩溶水位主要影响因素的基础上,利用多元相关分析法对岩溶水位进行模拟预测。研究表明:1965年以来焦作矿区的降水量并未出现明显下降趋势,岩溶水位的多年波动下降并非降水入渗补给量减少所致,主要与不断增长的城市开采量和矿井排水量有关;当开采总量降至4.1 m3/s时,最高水位将高出九里山泉口标高95 m,历史上的九里山泉群将会复涌。研究结果可为焦作在九里山一带建设山水园林景观提供依据。The change of water level of karst water in Jiaozuo mining area is a very important problem in Jiaozuo City construction under the influence of bi - directional factors of the closure of coal mine and the reduction of urban karst water exploitation. In this paper, the correlation degree of water level with rain- fall and exploitation was studied by slope grey relational analysis method. The moving average method and the Mann -Kendall nonparametric statistic method were used to analyze the change trend of karst water level, rainfall and exploitation since 1965. Based on the analysis of the main influencing factors of karst water level, the multivariate correlation analysis method was used to establish model to simulate and fore- cast karst water level. The results show that the precipitation in Jiaozuo mining area has not decreased ob- viously since 1965. The decline of karst water level is not due to the decrease of rainfall infiltration re- charge, but mainly related to the growing urban exploitation and mine displacement. When the total a- mount of exploitation is reduced to 4.1 m3/s, the highest water level will be 95 m higher than the Jiuli Mountain Spring mark elevation, and the Jiuli Mountain spring groups in the history would be poured back. The results of the study can provide the basis for the construction of landscape garden in Jiuli Mountain area in Jiaozuo.
