2000年6月，国家确定了170个大 中城市要在2003年6月底前在城市建设 工程中逐步限时禁止使用实心粘土砖， 湖南省的长沙、株洲、湘潭、娄底，益 阳、衡阳、郴州等7个城市名列其中。几 年来，湖南省“禁实”工作取得了较好 的成效，新型墙体材料发展迅速，但在 湘潭等地，“禁实”工作进展却不尽如 人意。 In June 2000, the government determined that 170 large and medium-sized cities should gradually ban the use of solid clay brick in urban construction projects by the end of June 2003, and Changsha, Zhuzhou, Xiangtan, Loudi, Yiyang, Hengyang and Chenzhou in Hunan Province 7 cities are among them. In recent years, Hunan Province has achieved good results in banning real-estate work. New wall materials have been developing rapidly. However, in Xiangtan and other places, progress in banning real-estate operations has been unsatisfactory.
