利用两种不同大气湍流结构常数模型，讨论了不同高度的湍流对大气湍流光学参数的影响。通过理论计算得出：相干长度和对数振幅起伏方差主要由低层大气湍流决定，而等晕角、倾斜等晕角、格林伍德频率和泰勒频率由对流层顶附近的高层湍流决定。分析了垂直高度30 km以下的3部分大气湍流对等晕角的贡献比例，在给定的不同强度湍流下，对流层顶附近的高层大气湍流贡献比例都大于25％，而低层大气湍流的贡献比例都小于3％。

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 the upper troposphere turbulence are all greater than 25%.
