洪山泉流量动态及影响因素分析

Discharge Dynamics of Hongshan Spring and Its Analyses on Influence Factors

以39年洪山泉流量观测资料为基础,对泉水稳定性、变化特征及影响因素进行了探讨分析,结果表明洪山泉39年的泉水流量动态曲线出现了4个高峰、4个低谷,峰谷交替时间间隔周期为8年左右。大气降水是洪山泉水的主要补给来源,对泉水补给存在着8年的滞后期,是控制着泉水的流量的主要因素,随着多年降雨量的减少泉水流量呈下降趋势,采煤及地下水超采改变了地下水的补经排条件,影响了洪山泉水量水质,也是洪山泉流量减少的重要原因,今后应加强洪山泉的保护,进行合理开发以达到可持续利用的目的。

Based on the discharge observation informations of Hongshan spring during 39 years, probe and analyses on stability? features of change and influence factors of spring water, showing that discharge dynamics curve of Hongshan spring during 39 years has appeared 4 peaks and 4 valleys, and the alternate time interval of peak and valleys about 8 years. Atmospheric water is main recharge source of Hongshan spring and there are 8 years of lagging period for recharge of spring water, it's main factor control on discharge of spring. The discharge of spring has emerged drop of trend along with decrease of rainfall in the many years. Coal mining and over mining of ground water have changed the conditions on recharge? watershed and drain of ground water, and influenced quantity and quality of water of Hongshan spring,it's also important reason on discharge increase of Hongshan spring .From now on, ought to strengthen protection of Hongshan spring and carry out reasonable exploitation, and to reach the purpose of sustainable utilization.
