【摘要】 自动化监测仪在地下水水位监测中已经广泛应用,但数据冗余、经费限制、资源不合理利用等问题使人们必须重视自动监测仪器采样间隔的科学性。本文采用时间序列分析方法,建立采样间隔与监测精度间的关系,得出华北平原地下水监测点大致分成三类:采样间隔不宜过小,人工监测宜能满足;采样间隔、监测手段宜因需调整;采样间隔很小,宜采用自动化监测。更多还原

【Abstract】 Automation monitoring instruments have been widely used in groundwater level monitoring,but scientific sampling interval of the instruments should be paid attention to because of data redundancy,lack of money and waste of resources.In this paper,the relation between sampling interval and monitoring precision is build by using time series analysis method.And three suggestions are made for the groundwater observation wells in the Huabei Plain as follows: 1) Sampling interval should be large enough for manual monitoring;2) Sampling interval and monitoring measures should be adjusted according to necessity;3) Sampling interval should be small enough for automation monitoring.更多还原
