城市更新是中国式现代化背景下城市发展模式转型的新着力点。以西方空间生产理论为核心线索，在中国语境下对存量空间生产过程中的三元辩证关系进行解读，并将其与城市更新演进历程相结合，系统揭示从“地本”到“人本”的城市更新价值取向演化逻辑，形成一套空间三元价值体系。在此基础上，从生命支持价值同化、政治经济价值异化和日常生活价值弱化三方面剖析当前城市更新发展面临的空间价值失序困境，并提出借在地化之势激活文化资本、凭数字化之力促进公平正义和用共同体之效恢复社会联结三条解决路径，以期为我国城市更新政策的制定提供参考。

Most current Global System for Mobile Communications （GSM） frequency planning methods evaluate the interference and assign frequencies based on measurement reports. Assigning the same or adjacent frequencies to cells close to each other will introduce co-channel and adjacent channel interference which will reduce network performance. Traditionally, man power is used to check and allocate new frequencies which is time consuming and the accuracy is not satisfactory. This paper presents an intelligent analysis method for optimization of co-channel and adjacent channel interference by exploiting cell configuration information. The method defines an interference evaluation model by analyzing various factors such as the base station layer, the azimuth ward relationship, and the cell neighborhood relationships. The interference for each frequency is evaluated and the problem frequencies are optimized. This method is verified by a large number of actual datasets from an in-service GSM network. The results show this method has better intelligence, accuracy, timeliness, and visualization than traditional methods.
