Abstract: In this paper, autocorrelation, space correlation, and integral scale of turbulence were discussed, using theory of turbulence statistics and field observation data. On leeward side of windbreaks, near X=1H-5H, turbulent correlations were not close due to the small scale of turbulence. The time scale of eddy is about 2—3 sec. (1.5m) and 3—8 sec. (5m), and space scale is 10—20m. The turbulence correlations were higher with the distance from windbreaks and the scale of turbulence increased. The time and space scale of eddies are about 15—20 sec. and 70—80m at the range X=20H-X=30H, respectively. Meanwhile, autocorrelation of turbulence confirmed the 2/3 power law.
