Abstract	The Qi Tai telescope (QTT) is a steerable 110 m radio aperture telescope that will be built in Xinjiang province, China. In this paper, we calculate the interference level limits, in dB(Wm(-2)Hz(-1)), at the feed aperture relevant for the science requirements and the technical parameters of the QTT. These flux densities are converted into field strength units, in dB mu V/m, for evaluation of the actual emission levels. Additionally, the side lobe gains of the receiver system will be determined from these key site locations. Based on high-resolution terrain data, a terrain model was constructed for the preliminary layout of the QTT site, in order to analyze the expected propagation losses from key locations to the telescope using the Longley Rice and Two Ray propagation models. Finally, the interference level limits for key activity areas are quantified accurately based on the limits of the feed aperture, the side lobe gains, and the propagation losses.
