Abstract: Experimental measurements of the edge plasma rotation and electric field have been carried out on both SOL and the boundary of the HL - 1M plasmas for Ohmic, Neutral Beam Injection（NBI）, Ion Cyclotron Resonance Heating（ICRH）, Low Hybrid Wave（LHW） Injection and Electric Cyclotron Reso- nance Heating （ECRH） with a Mach/Langmuir probe array. The radial profiles of the poloidal flow rotation velocity V_pol, the radial electric field Er and the poloidal electric field E_o are measured during experiments of NBI, ICRH, LHW and ECRH, respectively. In experiments of HL - 1M tokamak, NBI, ICRH, LHW, and ECRH were used to study the confinement improvement, the edge fluctuations and the radial transport.
