本文提出了当前新城区规划编制、管理中一对普遍存在的矛盾:针对同一个地块,以集约利用土地等各种名义提高容积率(所谓经济性),同时又不断扩大各类退界距离减少可利用土地(所谓环境好)。文章对其基本成因作了剖析,并引发了对空间环境的专业发展和制度环境的内在机理的系统反思。 In this paper, we propose a common contradiction in planning and management of the new urban area: increasing the floor area ratio (so-called economic) under various names such as the intensive use of land for the same land parcel, and at the same time expanding the various types of exiting distances Reduce available land (so-called good environment). The article analyzes its basic causes and initiates a systematic reflection on the professional development of space environment and the inherent mechanism of institutional environment.
