黑龙港平原区地下水利用水位水量控制指标分析

Controlling indexes of water level and pumped groundwater in Heilonggang plain area,Hebei Province

选取河北省黑龙港地区平原地下水开采区——沧县为典型示范区,在了解该区域基本情况的基础上,介绍了浅层和深层地下水开采量监测的几种方法,即:统计法、典型点法以及水电转化法;对运用这几种方法来计算工业、农业和人畜生活等地下水开采量的过程进行了分析研究。在分析过程中,借助于SPSS软件进行了多元回归分析;并建立了月水位变化与月开采量相关关系、年水位变化与年开采量相关关系,定性地确立了水位与埋深的相关关系。与此同时,根据典型示范区的实测地下水埋深等数据资料,与地下水开采量指标进行了拟合。分析结果可为水位控制和取水总量控制提供技术支撑和科学依据。

Cangxian County,in Heilonggang plain area,is selected as a typical demonstration area of groundwater exploitation.The basic situation of the area is briefly described.Several methods for monitoring shallow groundwater exploitation are introduced,such as statistical method,typical point method and power consumption calculation method,to briefly analyze the process of calculating groundwater exploitation in industry,agriculture,human and livestock.By using SPSS software,the correlations between water level variation and mining amount in monthly and annual level are established respectively,and the correlation between water level and buried level is established qualitatively.At the same time,the relation between groundwater level measured in the typical area and groundwater mining amount is fitted to provide technical support and scientific basis for water level control and water flow control.
