Abstract The transition of coal-exhausted city (CEC) has been a worldwide problem, the transition planning of the CEC is a synergetic procedure. When we look into the transition problem of a larger CEC, the difficulties for the city planner come from the synchronicity, otherness and complexity of the “Mine-City” system. Xuzhou City is the largest CEC in the world and has the most complex “Mine-City system”. The researches on the transition of Xuzhou would be a good example to the complex “Mine-City” system planning in the world. The bio-city is the best transition target for Xuzhou city. Based on this understanding, a “Classification-Strategy” method for Xuzhou city's eco-transition is proposed. The “Mine-City” system of Xuzhou is classified into 3 basic types: urban type, rural type and suburban type. The corresponding practical strategies are proposed. The “Classification-Strategy” method has the advantages of simple and practical, and can give the city planner a more comprehensive consideration of the planning elements during the eco-transition of the “Mine-City” system.

“矿山-城市”系统生态转型的“分类-策略”方法——以徐州市为例

摘要 煤炭枯竭城市（CEC）的转型是一个世界性的难题，CEC的转型规划是一个协同过程。当我们研究一个更大的CEC的过渡问题时，城市规划者的困难来自于“矿山-城市”系统的同步性、差异性和复杂性。徐州市是世界上最大的CEC，拥有最复杂的“矿山-城市系统”。徐州转型研究将为世界上复杂的“矿山-城市”系统规划提供一个很好的范例。生物城是徐州市最好的转型目标。在此基础上，提出徐州市生态转型的“分类策略”方法。徐州的“矿山-城市”体系分为城市型、农村型和郊区型3种基本类型。提出了相应的实践策略。“分类-策略”方法具有简单实用的优点，可以让城市规划者在“矿山-城市”系统生态转型过程中更加全面地考虑规划要素。
