Other Abstract	由于射电望远镜运行时对无线电信号的捕捉灵敏度高，所以，QTT无线电宁静区保护涉及范围广泛。为了确保新疆拟建的110米全可动射电望远镜（简称：QTT）运行环境安全，本文提出了一种预测限制区内的村庄及通讯基站干扰辐射的方法，从技术的角度分析了限制区内村庄和通讯基站对QTT的影响，结果表明，石河子二组、石河子三组、腰站子部分村庄不符合限制要求，与政府协商后期安排搬迁；通讯基站方面，江布拉克景区有三个大站不满足限值要求，对QTT的运行具有一定的影响。
Abstract	Radio telescope has the extremely high system sensitivity, the protect is very difficult. We proposed a prediction method to lower the electromagnetic interference in the radio quiet zone of QTT site. The influence of villages and communication base stations for QTT is analyzed from the technical point of the view, the results show that the group 2, Shi He-zi village, group 3, Shi He-zi village and Yao Zhan-zi village mentioned above do not meet the limit requirements. In consultation with the government, the villages that do not meet the limit requirements will be relocated to ensure a good electromagnetic environment at the QTT station. Through the simulated analysis of the radio wave propagation, it is found that three big power stations in the Jiang Bu-la-ke do not meet the QTT protection limit requirement.
