近100年来,珠江流域洪涝灾害频繁。分析这些洪涝灾害,除气候异常、降雨集中外,珠江流域严重的水土流失加剧了洪涝造成的险情和灾情。依据珠江流域二十多年的治理成效论述水土保持在珠江防洪减灾中的作用与地位。指出水土保持是流域经济社会可持续发展的重要基础,是江河防洪体系的重要组成部分,是减少河流泥沙、维护河流健康生命的根本措施,对减轻洪涝灾害、提高防洪抗灾能力具有重要作用。针对珠江流域水土保持工作存在的问题,提出今后的总体工作思路和工作重点。
In the past 100 years, frequent floods and disasters in the Pearl River Basin. Analysis of these floods, in addition to abnormal weather, concentrated rainfall, the Pearl River Basin, severe soil erosion exacerbated the floods caused the danger and disaster. Based on the governance achievements in the Pearl River Basin for more than 20 years, this paper discusses the role and status of soil and water conservation in the Pearl River flood control and disaster mitigation. It is pointed out that soil and water conservation is an important foundation for the sustainable economic and social development of the basin and an important component of the flood control system of the river. It is an essential measure to reduce river sediment and maintain the healthy life of the river, and plays an important role in reducing flood disasters and improving flood control and disaster resilience. In view of the problems existing in the work of soil and water conservation in the Pearl River Basin, the general work ideas and work priorities in the future are put forward.
