为找出山西省太原市境内交城断裂晋祠段岩溶井水位在2009年7月后快速上升的主要影响因素,采用支持向量机建立水位动态模型,对比分析断裂带所处的晋祠泉域内不同地段不同时段的水位变化,并对水位变化进行识别和验证。结果表明,支持向量机模型合理可靠,模型预测值与实测值的相关系数可达0.998;降雨量增加、地下水开采量减少是井水位上升的主要因素,但在水位快速上升时段,模型误差较大,说明此时段还可能存在其他影响因素。
In order to find out the main influencing factors of rapid rising of karst well water level in Jinci Section of Jiachen Section of Jiaocheng Section in Jiaocheng Section of Taiyuan City in Shanxi Province, the dynamic model of water level was established by using support vector machine to compare and analyze the different sections Water level changes at different time intervals, and water level changes identified and verified. The results show that the support vector machine model is reasonable and reliable, and the correlation coefficient between predicted and measured values is up to 0.998. The increase of rainfall and the decrease of groundwater extraction are the main factors of well water level rise. However, in the period of rapid water level rise, , Indicating that this period may also have other factors.
