深圳市移动通信基站专项规划环评中站址布局合理性研究

采用电磁辐射预测模式对不同制式、不同载频数时单幅天线的辐射水平及达标距离,以及单家运营商及多家运营商多种制式共存时的辐射水平及达标距离进行了预测。并以2G站和3G站单个制式的最大达标距离15 m作为最小防护距离,以三家运营商共址时的达标距离30 m作为最大防护距离,研究出一套基站站址适宜性分区的方法。研究结果表明,该方法能直观的划分出规划地块的适宜建设区、不适建设区及中间区,为基站的布局合理性提供判据。

Study on the Reasonable Layout of Shenzhen Mobile Communication Base Station selected in the Specific Planning Environmental Impact Assessment

This article used the electromagnetic radiation predicting model to estimate the radiation level and compliance distant of single antenna with different mode and different set frequency, also the radiation level and compliance distant of co-existence modes provided by operators. And the maximum compliance distance (15m) of single 2G and 3G style like as the minimum protection distance, while compliance distance (30m) with three operators using the same address like as the maximum protection distance. Meanwhile, a method on classifying a suitable base station was build up. The results indicate that the method can directly divide different areas among suitable and unsuitable building area, and intermediate areas for the planning block, and this could provide reasonable criteria for the base station layout.
