| 摘要: |
| 快速的城市化过程导致城市内绿地面积迅速减少，绿地所具有的拦截、渗透和存储降雨径流的滞蓄功能逐渐被削弱。城市内部绿地的滞蓄能力大小及其空间分布特征成为城市雨洪管理的重要研究内容。计算了绿地的滞蓄能力，并根据相关标准中50年一遇的降雨量评估了沈阳市绿地的滞蓄效能，得出绿地滞蓄能力对滞蓄效能有显著影响。然后分析了不同绿地滞蓄能力存在差异的原因及剩余的滞蓄潜力。最终结合沈阳市绿地滞蓄潜力的空间格局提出了绿地优化的建议。 |

| Abstract: |
| The rapid urbanization process leads to the rapid reduction of urban green space area, and the function of green space for interception, infiltration and storage of rainfall runoff is also gradually reduced. The storage capacity and spatial distribution characteristics of urban green space become an important research content of urban stormwater management. In this study, the storage capacity of green space was calculated, and the detention and storage efficiency of Shenyang green space was evaluated according to the 50-year rainfall in relevant standards. Then, the reasons for the differences in the storage capacity of different green lands and the remaining storage potential were analyzed. Finally, combined with the spatial pattern of the potential of green space storage in Shenyang City, the suggestions of green space optimization were put forward. |
