| 公园绿化覆盖率对人群情感恢复起到重要影响作用，但关于情感恢复的具体结果及效果的细化研究较为匮乏。选取重庆市沙坪公园中的6处空间为研究样本，以归一化植被指数（NDVI）区分空间绿化覆盖率，结合生态瞬时评估（EMA）以精确测度人群情感的恢复结果，并分析两者之间的关系，结果表明：1）以硬质铺地为主、绿化覆盖率相对较低（0.38≤NDVI≤0.45）的公园空间，对人群外向情感恢复起主要影响作用；以软质绿化为主、绿化覆盖率相对较高（0.58≤NDVI≤0.72）的公园空间，对人群内向情感恢复起主要影响作用，且随绿化覆盖率提升，人群对应形成的外向或内向情感恢复效果均显著提升；2）公园绿化覆盖差异将诱导人群形成外向或内向2条情感恢复路径；3）在硬质铺地类空间中，丰富植被色彩及群落层次搭配，完善配置功能设施，有助于提升人群外向情感的恢复效果；在软质绿化类空间中，提升绿化覆盖率、植被丰富度，降低空间视野开阔度，有助于提升人群内向情感的恢复效果。研究结论可为公园恢复性环境理论体系的完善及实际项目建设提供思路借鉴。 |

| Abstract: |
| The green coverage rate in park space plays a major role in the emotional recovery of the crowds. However, detailed researches on the specific results and effects of emotional recovery are relatively scarce. In this research, six spaces in Shaping Park of Chongqing City are selected as samples, and the normalized difference vegetation index (NDVI) is used to distinguish the spatial green coverage rate. Combined with the ecological momentary assessment (EMA), they are applied to accurately measure the results of the emotional recovery of the crowds, and analyze the relationship between the two. The results show that: 1) The park space, mainly with hard pavement and relatively low green coverage rate (0.38≤NDVI≤0.45), has a major impact on the recovery of people’s outward emotions; The park space, with soft green space and relatively high green coverage rate (0.58≤NDVI≤0.72), mainly greening, plays a major role in the recovery of introverted emotions of the crowds. With the increase of the green coverage rate, the recovery effect of the extroverted or introverted emotion formed by the crowds is significantly improved. 2) The difference in park green coverage will induce the crowds to form two emotional recovery paths: extroverted or introverted. 3) In the hard paved space, enriching vegetation colors and community levels, and increasing the configuration of functional facilities are helpful in improving the recovery effect of the crowds’ extroverted emotions. In the soft green space, increasing the green coverage, vegetation richness and reducing the openness of the space are helpful in improving the recovery effect of the crowds’ introverted emotions. The research conclusions can provide a reference for the improvement of the park restorative environmental theory system and the actual project construction. |
