white-space: normal; box-sizing: border-box;"><br style="box-sizing: border-box;"  /></p><p style="clear: none; white-space: normal; box-sizing: border-box;">进一步的研究还表明，经济越发达，多中心性越明显。</p><p style="clear: none; white-space: normal; box-sizing: border-box;"><br style="box-sizing: border-box;"  /></p><p style="clear: none; white-space: normal; box-sizing: border-box;">清华大学团队的这篇研究文章，刊登在近期出版的《上海城市规划》杂志上，4名作者有3人来自于清华大学建筑学院。他们以全国658个城市为研究对象，所使用的基础数据包括一份电子地图在某个周三下午3时15分许的市民多项活动，数据粒度精细到个人，“以市民借助互联网的活动为出发点来重新定义城市中心。”</p><p style="clear: none; white-space: normal; box-sizing: border-box;"><br style="box-sizing: border-box;"  /></p><p style="clear: none; white-space: normal; box-sizing: border-box;">研究人员对获取的数据进行处理后，计算各个地区内聚类的人群密度和人流速度，综合计算出聚类地点的活跃程度。计算结果用不同的颜色和亮度反映人流量的空间差异：颜色越趋近于红色表示人群密度相对越高，越趋近于绿色表示人群密度相对越低，从红到绿连续变化，从而筛选出一个城市的（潜在）中心节点。</p><p style="clear: none; white-space: normal; box-sizing: border-box;"><br style="box-sizing: border-box;"  /></p><p style="clear: none; white-space: normal; box-sizing: border-box;">文章的第一作者、清华大学建筑学院博士研究生李娟告诉成都商报记者，成熟型多中心城市中，成都的中心面积总和为38.36平方公里，仅次于广州、深圳、上海、北京，位居第五；从中心数量上看，成都则以17个和重庆、上海并列第八。</p><p style="clear: none; white-space: normal; box-sizing: border-box;"><br style="box-sizing: border-box;"  /></p><p style="clear: none; white-space: normal; box-sizing: border-box;">李娟介绍，近年来伴随着城市化进程的推进，中国的城市空间结构有朝向多中心发展的趋势：如天津、上海等地的城市空间结构从最初的同心圆，逐渐演变为多中心模式。</p><p style="clear: none; white-space: normal; box-sizing: border-box;"><br style="box-sizing: border-box;"  /></p><p style="clear: none; white-space: normal; box-sizing: border-box;">研究人员认为，正是空间结构的改变，使城市由单中心发展到多中心，中心数量逐渐变多，面积也逐渐增大，呈现遍地开花的景象。李娟认为，在城市规划中，对于城市空间结构的设计，多中心既要作为城市的主要标签创造吸引力，也要承担发挥城市凝聚力的职能。</p><p style="clear: none; white-space: normal; box-sizing: border-box;"><br style="box-sizing: border-box;"  /></p><p style="clear: none; white-space: normal; box-sizing: border-box;">研究还发现，包括成都在内的上述12个成熟型多中心城市，其就业人口、人均GDP与中心数量的高相关性证明：经济越发达，多中心性越明显。对于行政等级较高、经济实力较好的城市，往往能够与多中心发展形成良性互动的关系。</p></section></section></section></section></section><section style="width: 15px;
