大汶河生态型河道综合整治研究 作者： 班级： 指导老师： 摘要：本文结合我国平原河道的水质环境与生态环境现状，以大汶河泰安段为研究对象，分析了大汶河河道生态环境和工程措施治理中所面临一些问题以及产生这些问题的原因。本文将从河道生态治理角度，以人与自然和谐共处为治河理念，对大汶河河道整治进行研究，同时，对大汶河泰安段水污染控制与水质预测进行了初步研究，分析了产生水污染的原因，选择合适的水质模型，进行纳污能力计算及水质预测。“南水北调”东线工程比较突出的问题就是水质污染问题，大汶河水质直接影响其供水质量。按照规划水平年规划的水质目标，预测了治理后的结果，并结合实际提出了一些水污染控制措施，对指导工矿企业排污、城市规划布局、水资源合理开发利用与保护、以及国民经济和社会可持续发展等方面具有重大科学意义。 关键词：生态河道；水质预测；河道整治；护岸材料 The comprehensive improvement of Dawen River to become ecological river Author: Major: Instructor: Abstract:Considering the water quality and the status of ecological environment of the plain rivers in China,this paper takes the part of the Dawen River around Taian as the study object and analyses the problems roused from the management of Dawen River channel ecological environment and the engineering measures and the reasons of these problems. The paper will make a research about the Dawen River improvement from the angle of river ecosystem management and the river regulation philosophy of man-and-nature harmonious coexistence .At the same time,the paper also undertakes a preliminary study about Dawen River’s pollution control and water quality prediction ,and analyzes the reasons of water pollution by choosing proper water quality model and the right calculation of dirt assimilative capacity and water quality prediction.The comparatively salient problems of the the eastern route of the “south-to-north water transfer” are water pollution,which directly affects the quality of the water supply.According to the water quality objective of target year of water conservancy planning,this paper gives out the prediction of the the result after the improvement. It also put forward with some measures to control water pollution based on the reality.，which has great scientific significance in many aspects, such as the guidance of industrial and mining enterprises’ pollution discharge,the layout of urban plann
