陕西渭河流域主要环境问题及其治理

Analysis on the Main Environmental Problems in the Weihe River Basin in Shaanxi Province

日益恶化的环境问题已成为制约陕西渭河流域社会经济可持续发展的重要因素。通过历史统计资料分析和对研究区环境现状及研究成果的回顾与总结,得到如下结论:①水资源紧缺、水质污染、水土流失、洪涝灾害频发是研究区主要环境问题。②改善环境的有效手段是制定以资源环境科学研究为基础,以流域综合管理为目标,以结构调整为主线,以科技进步为动力的流域综合管理规划,通过实施洪水资源化、降低潼关高程、依法进行水污染治理、加强流域水土保持等措施,实现流域水资源合理开发利用、减轻洪灾损失、改善流域环境。

Environmental problems have become more and more serious and as the factors restricting the sustainable economic development in the Weihe River Basin in Shaanxi Province.After analyzing the historical statistical data and reviewing the research achievements,some conclusions were got.The main environmental problems in the drainage basin are the shortage of water resources,water pollution,water loss and soil erosion and frequent flood.It was recognized that the effective ways of solving the environmental problems are to regard the integrated management as the target,take the restructure as main line,and make scientific and technological progress as the power.Of course,all these are based on the research on environment and resources.In order to achieve the rational development and utilization of water resources,reduce flood disaster and improve ecological environment,the effective measures are to utilize floodwater,decrease the Tongguan elevation,control water pollution and strengthen soil and water conservation.
