在整理分析大量河道变化基础资料的基础上,总结了影响渭河下游生态环境改善和社会经济可持续发展的5个主要问题,即:潼关高程居高不下,泥沙淤积及河床抬升速度加快,渭河尾闾段及12条南山支流河口淤塞严重,防洪工程隐患多、抗洪能力低,渍涝灾害及河道水环境问题突出。结合对相关问题成因及区域现状的认识,提出了以渭河综合治理为契机,全面实施“下排、上拦、中固疏”的治理思路,总结了降低潼关高程、完善防洪除涝工程体系、建设拦沙减淤及水沙调控工程、加强河务统一管理等4条治理和管理建议。
Based on the analysis of the basic data of a large number of river changes, five major problems that affect the ecological environment improvement and social and economic sustainable development in the lower reaches of the Weihe River are summarized. They are as follows: the high elevation of Tongguan, siltation and speeding up of the riverbed, The tailrace section and 12 Nanshan tributary estuaries have serious silting up, many flood control projects have hidden dangers, low flood resistance capability, waterlogging disaster and river water environment problems. Combined with the cognition of the causes of the related problems and the status quo of the region, this paper put forward the idea of harnessing the comprehensive management of the Weihe River as a turning point and comprehensively implementing the governance idea of “laying down, stopping and changing solid” to summarize the measures to reduce the elevation of Tongguan and improve the flood control and waterlogging prevention works System, construction of sediment reduction silt and sediment control project, strengthen unified management of river four governance and management recommendations.
