河流是一个有机的生态系统,多种生物相互依存。长期以来,水土流失现象不断加剧,生态环境持续退化,河流的生态系统健康受到威胁,已经产生了严重的生态危机。采取行之有效的水土保持措施,减少泥沙及污染物向下流河流输移,是改善河流生态系统环境,维持河流生态系统平衡的有效措施。
The river is an organic ecosystem in which multiple organisms are interdependent. For a long time, the phenomenon of soil and water loss is aggravating, the ecological environment continues to deteriorate, and the ecosystem health of the river is threatened, which has already caused serious ecological crisis. Proper measures of soil and water conservation to reduce sediment and pollutant transport to downstream rivers are effective measures to improve the ecological environment of rivers and maintain the balance of river ecosystems.
