城市河湖水质改善与保障技术研究

Study of water quality improwement and the protective technique of urban rivers and lakes

西北地区干旱少雨造成的水资源紧张及水环境恶化,已成为中国西部大开发中水环境治理的难题.本研究结合陕西省渭河宝鸡市区段生态治理工程,分析了生态治理工程对宝鸡市区河湖水质的影响,并在市区人工湖浅水区进行了芦苇带对湖水和渭河公园中湿地对河水水质改善效果的试验研究.试验结果表明,芦苇带和湿地对城市河流水质改善效果良好.根据实地调查和试验结果,提出宝鸡市在治理工程后的进一步改进措施,分析了在市区河湖进行生态修复的可行性.为城市河湖的水环境系统修复提供科学依据.

The shortage of water resources and water environment exacerbation caused by drought and little of rain in northwest China has become the main puzzle of water-controlling during the China＇s Western Development. Combining with the ecological restoration project of Weihe River in the reach of Baoji City, the,restoration project＇s effects on the water quality of rivers and lakes in Baoji City have been analyzed in this paper. The experiments of reeds＇ betterment to lake water quality in shoal area of artificial lake and wetland to urban river water quality in Weihe Park have been put to practice respectively. According to fieldwork and the results, based on the analyses of the feasibility of water quality ecological restoration in t;rban rivers and lakes, further improving measures after the restoration project in Baoji City have been brought forward, providing a scientific gist for the aquatic environment systematic restoration of urban rivers and lakes.
