城市河道生态修复技术研究进展

Research Progress on Urban River Ecological Restoration Technology

随着城市经济和社会的发展,城市河道受到了不同程度的环境污染,严重影响了城市人们的生活质量,并对城市下一步的可持续发展起到了严重的阻碍作用,近年来由于各界的普遍关注,有关城市河道生态修复技术的研究工作也取得了相应的发展。文章首先概述了城市河道的现状,并对城市河道生态修复的内涵进行了阐述,然后介绍了一些国内外有关城市河道生态修复技术研究的现状,并对城市河道生态修复技术中的物理修复、化学修复和生物修复技术进行了系统的分类阐述;在最后展望了未来城市河道生态修复技术的发展方向。

Urban rivers were polluted b different levels with the development of society and economy. It seriously affected the life quality of urban citizens and become an impediment to the sustainable development of cities. Due to the widespread concern from all walks of life, the researches on urban river ecological restoration technology have developed in recent years. The article first summarizes the present situation of urban river and expounds the connotation of river ecological restoration. The domestic and foreign research situation in this field is introduced, and the physical, chemical and biological remediation technologies are systematically introduced. Finally, the future development prospect of urban river ecological restoration technology is projected.
