| 摘 要： | 通过观测，理论计算和实验研究，探讨了固原地电台测区内搭建蔬菜大棚后北东及东西测道视电阻率测值快速上升的原因，定量解释了搭建蔬菜大棚对固原地电观测的影响，并研究和总结了这种影响的机制。从而认为，2008年3月下旬固原视电阻率出现的高值变化不属于地震异常，并为今后判断引起地电测值变化的原因提供了依据。

| Abstract: | Through observation, theoretical arithmetic and experimental study, we research the cause of rapid ascending on the NS and EW resistivity observation after the building of green house in observational areas in Guyuan Seismic Station. The influence of green house building on the apparent resistivity was interpreted quantitatively. The mechanism of the influence is also studied and summarized. In this paper, it was proved that the high value of apparent resistivity observation in late of March, 2008 is not an anomaly relative to earthquake. This result provides us the foundation to identify resistivity observation either the interference or abnormal variation about earthquake. |
