The intense femtosecond linear and nonlinear effect can affect the propagation of intense femtosecond laser pulse in oxygen. The high⁃order Kerr effect plays an important role in these effects. The numerical simulation of a 2⁃D axisymmetric la⁃ser propagation model was performed for the propagation of intense femtosecond laser pulse in oxygen. The impact of the varied nonlinear refractive index of high⁃order Kerr effect on the femtosecond laser pulse′s propagation in oxygen is investigated.%强飞秒线性和非线性效应会影响强飞秒激光脉冲在氧气中的传输，非线性高阶克尔效应对其影响尤为重要。针对在氧气中的飞秒激光传输基于一个二维轴对称激光传输模型进行数值模拟，研究了激光在氧气中传输受到高阶克尔效应非线性折射率变化的影响。
