Abstract Objective To explore the effect of plant impact on electric and magnetic field distribution of 110 kv overhead power transmission lines. Methods The health hazards of 50Hz EMFs,research Status of 50Hz EMFs distribution of 110kV are elaborated, and 50Hz EMFs of 110 kV Overhead Power Transmission Lines in no vegetation area, lawn, shrubs, tall trees area were measured and analysized PMM8053A. Results Plants can weaken the 50Hz electric fields obviously,but do the little work on the 50 Hz magnetic fields. The regression rate of electric fields is from 6.1%~99.9%. Furthermore,the regression rates of electric fields in lawn, shrubs, tall trees area were 6.0%~13.6%、32.4%~37.1%、98.3%~99.9%. At the same time,the regression rates of magnetic fields were 6.0%~10.6%. Conclusion Plants Impact on 50 Hz electric fields and 50 Hz magnetic fields was different. Significant on the 50 Hz electric field. The regression rate of electric fields in tall trees area was over 90%.
