摘　　要：分析了我国地面电视频谱使用情况,提出了研究人为噪声的重要性和紧迫性,归纳了地面数字电视系统中的人为噪声容差和最小中值等效场强的计算方法,为我国地面数字电视覆盖网规划计算和将采米波频段的数字化规划提供了技术参考。In this paper, terrestrial television spectrum usage in China is analyzed. The importance and urgency of man-made noise research are also put forward. The methods of man-made noise allowance and equivalent minimum median field strength for coverage calculations are studied. This paper provides a technical basis and reference for the coverage planning calculation and the digitization of VHF Digital Terrestrial Television Broadcasting System.
