中文摘要：

为进一步了解国民休闲状况，本文基于徐州居民利用绿地开放空间的调查问卷数据，从时间距离（行程时间）和空间距离两个方面展开，并结合不同交通方式下的空间距离分布，对居民利用绿地开放空间的空间结构特征进行了较为详细的分析；同时，对绿地开放空间的使用偏好和影响因素进行了统计分析。结果显示：时间距离上，休闲者行程时间通常大于30分钟；空间距离上，5km是人们日常休闲活动空间临界值，当小于5km时，人数呈波动状态，当大于5km时，人数呈现距离衰减趋势；在不同的交通方式下，空间距离呈现明显的圈层分异；休闲者在选择空间过程中偏好滨水型及带有游乐场的绿地开放空间。研究结果对绿地开放空间的规划、设计与建设具有一定的参考性。
