Abstract: 【Objective/Meaning】The transformation design of rain garden based on the concept of LID was carried out on the waste plot on the south side of Gongguan Bridge in Fujian Vocational College of Agriculture, thus to provide reference for the construction of rain garden landscape which integrated the rainwater utilization, water purification and leisure & recreation under the concept of low impact development. 【Methods/Procedures】Based on the full analysis of the status quo and hydrological conditions of the plot, and by means of the measures such as plant configuration and the construction of LID foundation engineering, the rain garden was built by utilizing the blocking, absorption and filtering functions of plants, the absorption, infiltration and storage functions of soil; and the interception, collection, decentralization efficiency of LID foundation engineering.【Results/Conclusions】Through the scientific use of LID engineering technology and landscape construction means, the infrastructures including ecological leisure areas, rain landscape pools and circular wooden trestle were constructed, effectively solving the prominent problems such as the land's poor water circulation capacity, poor ecological environment, and the deterioration of natural landscape.
