中文摘要：

环首都贫困带是围绕首都形成的贫困区域，该区域的发展状态与首都形成了巨大反差，这个贫困带就像一个“破围脖”围住了首都。这种状况是由首都和环首都区域之间不对称发展所造成的。为了将这个“破围脖”换成“金项链”，必须在首都与环首都地区之间构建“软区划”，通过“三Q＋三C”模式的城市体系建设，让首都与环首都地区进行融合发展。在这种前提下，环首都区域与北京这个大都市之间就可以实现平等对话。在京东城市群构建过程中，要重点强化遵化、宽城、唐山、卢龙等几个次级城市团，并且在京东城市群内部要着力构建一小时城市圈，在这种思路下京津冀之间统一的“血液循环系统”也就形成了。

英文摘要：

The ＂poor belt around the capital city＂ （PB） refers to the poor areas around the capital city, which reflects the huge contrast between the development status of PB and the capital city. PB circles capital city like a broken scarf. This situation is caused by the unbalanced development between PB and the capital. In order to turn this ＂broken scarf＂ into ＂gold necklace＂, the idea of ＂soft administrative division＂ must be shaped, and through constructing the urban system of ＂3Qs ＋ 3Cs＂, the capital and PB can be integrated together. Under this premise, an equal dialogue between Beijing as a metropolis and the area around the capital （AAC） can be made. During the process of constructing JingDong urban agglomeration, some secondary cities such as Zunhua, Kuaneheng, Tangshan and Lulong should be strengthened, a onehour-city-circle in this way can be shaped in the JingDong urhan agglomeration, and then the unified ＂blood circulation system＂ can be constructed as well.
