Research on Rain Garden Design of Pocket Park Based on Sustainable Development
This paper takes the rain garden project of a city pocket park as an example to deeply explore the design and construction of rain gar-den.The research results show that the project successfully utilized 150 m2 of space,achieved 85%rainwater collection rate and 90%rainwa-ter utilization rate,took 3 days to complete the soil improvement work,and increased the soil organic matter content to 3.5%.At the same time,the project biodiversity index reached 2.8 and the ecological balance index reached 85%,exceeding the expected requirements.But there is still room for improvement,especially in terms of further improving rainwater harvesting rates and ecosystem optimization.
