Based on two theoretical models of refractive index structure parameters, the influence on atmosphere turbulence optical parameters exerted by atmosphere turbulence in different heights are discussed, including coherence length, isoplanatic angle, tilt isoplanatic angle, Greenwood frequency, Tyler frequency, and log-amplitude variance. Coherence length and log-amplitude variance are mainly controlled by the lower atmosphere turbulence, but isoplanatic angle, tilt isoplanatic angle, Greenwood frequency, and Tyler frequency are controlled by the upper troposphere turbulence strongly. Considering the importance of isoplanatic angle, the contribution rates of three parts of atmosphere turbulence are studied. The contributions of the lower atmosphere turbulence are all less than 3%, and those of theupper troposphere turbulence are all greater than 25%.
