摘要
随着中国城镇化率超过60%,城市发展开始由过去大规模的增量建设向存量提质改造和增量结构优化并重转变,城市更新在这个过程中发挥着重要作用。城市更新从一种技术手段,向综合的政策转变。在当前实践中,城市更新的模式选择仍缺乏一定的客观性,呈现粗放化的态势。通过对城市更新动力的分解,发现更新模式的选择与主导力量之间存在直接关联。本文以研究区域内地块所受的主要动力作为更新类型的评判标准,构建评价指标体系。以丹江口市老城区为例开展实证研究,依据评价结果对更新单元进行类型划分,并根据不同的类型提出针对性的更新模式选择建议。研究表明,基于动力差异评价得到的单元更新类型,是客观选择更新模式的重要依据,对城市更新的精细化发展、促进更新规划的科学实施具有重要意义。
With China’s urbanization rate exceeding 60%,urban development has begun to shift from large-scale incremental construction in the past to a simultaneous focus on quality improvement and renovation of stock and optimization of incremental structure.Urban renewal is an important means of solving urban problems and promoting healthy and sustainable urban development,and is a strategic hand for promoting high-quality urban development.By combing through the literature on the relevant aspects of urban renewal,it can be found that although there have been more studies on the transformation of urban renewal mode and the rational choice of renewal mode.However,in the current practice,the choice of urban renewal model still lacks a certain degree of objectivity,mostly focusing on economic interests,and lacks a comprehensive consideration of how to balance the interests of all parties and realize multi-dimensional goals.Due to the lack of in-depth analysis of the motivation for regeneration and objective basis for the selection of regeneration mode,the efficiency of regeneration work is low,and the process of regeneration loses sight of the other side and contradictions occur frequently.Therefore,analyzing the main drivers of urban renewal,proposing the selection of renewal modes,and improving the objectivity of the selection of renewal modes are important issues that need to be resolved urgently in urban renewal.Through organizing and analyzing the studies on the drivers of urban renewal,it is found that urban renewal is mainly driven by three forces:public force,government force and market force.At the macro-level,these three forces often act on the land parcels in a dynamic way of superposition,penetration,interaction and balance to promote the renewal;at the meso-level,although each land parcel in the city is subjected to the three forces at the same time,there exists a clear difference,and the one with the greatest intensity is the dominant force of the land parcel;and at the micro-level,the superimposition of the
