生物滞留设施研究进展

RESEARCH PROGRESS OF BIOLOGICAL RETENTION DEVICES

通过分析近年来生物滞留设施在土壤介质、气候与热冲击、生物多样性、生命周期成本等方面的研究内容得到,优化土壤介质可提高系统的处理性能。增加模型的兼容性与输入端控制可提高模型预测的准确性。小规模设施耐热冲击性能较好。生物滞留设施相比草坪、花园有更丰富的生物多样性,利用植物根系与生物多样性增强设施的性能还有待研究。通过主动性控制指导、加强施工段控制可降低设施的周期成本,成本模型预测的准确性还需加强基础资料的收集与资源的共享。

The studies on biological retention device in recent years from aspects of the soil medium,climate and thermal shock,biological diversity and life cycle cost were analyzed. The analyses results showed that： The optimization on the soil medium can improve the processing performance of the system; the increase in the compatibility of the model and the input control may improve the accuracy of model prediction; the small-scale facilities is characterized with good thermal shock performance; compared with the lawn and garden,the biological retention device has more abundant biodiversity. The cycle cost of the device may be reduced via initiative control guidance and the intensification of the construction section control,and it is required to strengthen the collection of basic data and the sharing of sources for the accuracy of cost model prediction.
