With the increase in aperture and observation frequency of radio telescopes, there is a growing demand for enhanced pointing accuracy. However, telescope is operated at the field station, and the influence of wind disturbances on telescope pointing accuracy cannot be ignored in high frequency observation. Due to the time-varying characteristics of wind disturbances, the existing wind resistance methods cannot guarantee the effective observation time of large aperture and high pointing accuracy telescope in high frequency. Therefore, a method to improve the wind environment of the site based on the precise arrangement of wind barriers is proposed. The wind barrier simulation model is built, and the average error of the two porosity wind barriers is 3.7% and 6.1% respectively by comparing the simulation results with the measured data of the wind tunnel, which ensures the reliability of the wind barrier model. The QiTai radio Telescope (QTT) site in Xinjiang is taken as an example. The computational domain model is developed based on the slope terrain of the QTT site, and a series of wind field simulation tests are conducted to investigate the impact of different heights and porosities of a single wind barrier on downstream wind protection effectiveness. The parameters for simulating the north-south wind barrier are determined based on an appropriate height and optimal porosity. The results indicate that combining the determined height with a porosity of 0.1-0.1 yields the most effective wind reduction in the antenna area, with south winds experiencing a decrease in speed by over 75%.
