北京城区广场分布、辐射及其文化生产空间差异浅析

广场是城市文化活动的重要载体，是城市中重要的文化生产空间。文章首先选择北京城区广场作为研究对象，首先调查了三级广场的分布状况，结合人口分布对广场分布进行了评价；其次调查了北京城区一个典型剖面上的4个广场，用格林方法确定了4个广场之间的空间分割点，并依据对广场活动者的调查，确定了每个广场的空间辐射范围的平面形态，从而确定了这4个广场文化生产空间的大致范围；第三，调查了广场的文化活动类型，并将活动类型的差异与城市文化空间的圈层进行了比较，从而解释了广场文化产生差异的原因。结论是，城市广场的建设属于城市实体空间建设的一种形式，它是人们自觉的、理性的行动，本着公平的原则建设广场，将使城市各个地方的居民具有依托广场开展文化活动的可能，并借助广场创造城市新的多元的文化。
