基于低影响开发(LID)理念的雨水花园规划探索——以福建农业职业技术学院攻关桥南侧地块改造为例

Exploration on the Planning of Rain Garden Based on the Concept of Low Impact Development(LID)——Taking the Reconstruction of the Plot on the South Side of Gongguan Bridge in Fujian Vocational College of Agriculture as an Example

【目的/意义】对福建农业职业技术学院攻关桥南侧荒废地块进行基于LID理念的雨水花园改造设计,为构建低影响开发理念下的集雨水利用、水质净化、休闲游憩于一体的雨水花园景观提供参考依据。【方法/过程】在充分分析研究地块现状和水文条件的基础上,通过植物配置、LID基础工程建设等措施,利用植物的阻滞、吸收、过滤作用;土壤的吸收、渗透、蓄含功能;LID基础工程的截留、收集、分散等效能构建雨水花园。【结果/结论】通过科学运用LID工程技术和景观营造手法,构建生态休闲区、雨水景观池、环形木栈道等基础设施,有效解决了地块水循环能力差、生态环境恶劣、自然景观恶化等突出问题。

【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.
