农村河道生态治理模式研究

随着社会经济的发展，农村河道侵占严重，水面积锐减，河道淤积导致水利生态功能弱化，河道坍塌导致植被生态弱化，水环境受到很多污染源的影响，特别是农村面源污染。对农村河道的治理应该从水环境治理和河道结构治理两方面着手。河道水环境模式有循环利用生态治理模式、整体优化生态治理模式、多尺度相结合的生态治理模式、多技术集成的生态治理模式。河道结构治理模式包括自然生态型河道治理、工程生态型河道治理以及景观生态河道治理三种治理模式。

Ecological Treatment Model of Rural River

With the development of economy, many rural rivers have been occupied, and have been badly polluted so that ecological functions of these rivers have been destroyed. So it is important to use ecological method to treat water environment and structure of these rivers. Treatment models of water environment include recycling treatment model, optimizing treatment model and multi-scaling treatment model. Treatment models of structure have natural treatment model, engineering treatment model and landscape treatment model.
