| 城市的高强度开发建设如何影响城市绿地的渗蓄效能值得研究，可解决现有研究由于原型观测量不足造成的参数误差，实现城市雨洪韧性管理的科学预测和精准调控。以沈阳市三环内主城区为研究范围，将土壤容重作为因变量，选取不同自变量例如绿地类型、容积率、建设密度、建筑高度、用地开发年限、地形高程、绿化覆盖率、下垫面硬化比例等用地开发强度的相关因子，进行多元线性回归分析，总结用地开发强度对城市绿地渗蓄效能的影响机制。结果表明，在城市开发建设过程中，相关工程做法等人工干预因素对城市绿地的渗蓄效能产生显著负向影响。拓展了交叉学科理论成果的创新性应用领域，提出有效提高城市绿地渗蓄效能的关键方法，为韧性城市的更新改造建设提供理论依据。 |

| Abstract: |
| How the high-intensity urban development and construction affect the hydrological storage efficiency of urban green space is worth studying. It can solve the parameter errors caused by insufficient prototype observations in existing studies, and realize the scientific prediction and precise regulation of urban stormwater resilience management. Taking the third ring road of Shenyang as the research scope, selecting soil bulk density as the dependent variable, and different independent variables such as green space type, floor area ratio, construction density, building height, land development years, terrain elevation, green coverage, and underlay hardening ratio, the related factors of land development intensity were analyzed by multiple linear regression analysis, and the influence mechanism of land use development intensity on the Hydrological Storage Efficiency of urban green space was studied and summarized. It reveals the significant negative impact of relevant engineering practices and other human disturbance factors on the hydrological storage efficiency of urban green space in the process of urban development and construction, and expands the innovative application fields of interdisciplinary theoretical results. The key method of applying design methods to effectively improve the efficiency of urban green space infiltration and storage is put forward to provide a theoretical basis for the renewal and reconstruction of resilient cities. |
