【摘要】 近年来，随着互联网、3S技术及智能定位设备的迅速发展，LBS数据越来越广泛地被应用在活力研究领域，文章通过基于LBS数据的百度热力图，对聊城市主城区绿地空间的时空特征进行了探讨。结果表明：(1)聊城市主城区绿地使用活跃度较低，空间分布不均衡；(2)公园绿地使用活跃度水平较为稳定，与早晨相比居民更喜欢晚间访问绿地。在此基础上，提出了一些建议与对策，为今后城市绿地的规划发展提供了一定的参考。更多还原

【Abstract】 In recent years, with the rapid development of the Internet, 3S technology and intelligent positioning equipment, LBS data has been more and more widely used in the field of vitality research. The paper discusses the spatial and temporal characteristics of green space in the main urban area of Liaocheng through Baidu heat map based on LBS data. The results show that:(1) the green space in the main urban area of Liaocheng City is relatively low in use activity and uneven in the spatial distribution.(2) The activity level of the use of green space in the park is relatively stable, and residents prefer to visit the green space at night compared to the morning. On this basis, some suggestions and countermeasures are put forward, which provide certain reference value for the planning and development of urban green space in the future.更多还原
