Tradition has it that many,many years ago,there lived on the yellow river a river god known as he bo.one day ,he bo stood on the riverbank and watched the turbulent waves from the west surging forward to the east.he said both excitedly and conceitedly:how big the yellow river is !
相传很久很久以前,黄河里有一位河神,人们叫他河伯。何伯站在黄河岸上。望着滚滚的浪涛由西而来,又奔腾跳跃向东流去,兴奋地说;黄河真大呀,世上没有哪条河能和它相比。

In order to draw a circle around coarse sand concentrated coming area in sediment-laden and coarse sand area of the middle Yellow River,the paper makes macro analysis on the factors of geological structure,lithology of stratum,category of landforms and hydrometeorology of the sediment-laden and coarse sand area in the middle Yellow River and regional difference related with coarse sand production.
为在黄河中游多沙粗沙区确定粗泥沙集中来源区,从黄河中游多沙粗沙区地质构造、地层岩性、地貌类型、水文气象等因素与产粗泥沙关系的区域差异对粗泥沙集中来源区进行了宏观判析,认为在黄河中游多沙粗沙区范围内,吴旗—志丹—延安—延长一线以北、东胜—准格尔—清水河一线以南、吴旗—榆林—神木—大柳塔一线以东至晋西北黄河沿岸的范围是侵蚀最为严重的地区,也是粗泥沙集中来源区的宏观待选范围。

According to basic analytical methods of environmental quality standards for surface water in China(GB3838-2002),we used the 2002-2006 monitoring data to evaluate and characterize water quality condition of Lanzhou reach of Yellow river,based on the Nemerow index and variance analysis of the mean square deviation.
根据2002-2006年黄河兰州段水质监测数据,按照《地表水环境质量标准》GB3838-2002中Ⅲ类水质标准,确定污染物的污染程度,选用内梅罗水污染指数法,运用方差分析,对黄河兰州段水质现状进行评价分析,结果表明:(1)黄河兰州段水体的主要污染物是粪大肠菌群和总氮;(2)大量未经处理的生活污水排放是黄河兰州段的主要污染源;(3)针对黄河兰州段生活污水污染现状,提出源头治污思路。

Based on the unique characteristics of the Yellow River and previous research on its ecological water requirement, the present paper recommends that the water requirement for transport in the flood season and base ecological flow in non-flood season should be both included in the ecological water requirement. The water requirement for transport is 80 × 108-120 × 108 m3 per year if the bankfull discharge carries the largest sediment and contaminant load over a long period of time. The base ecological flows in non-flood season at Huayuankou and Lijin stations are 80 × 108-100×108 m3 and 50 × 108-60 × 108 m3, respectively.
通过分析黄河下游1958~2000年实测生态可用水,探讨生态需水量内涵,根据黄河特殊性及黄河生态需水量的研究现状,将维持和保护河流功能的黄河下游生态需水量分为汛期输运水量和非汛期生态基流量,在平滩流量输运能力最强的前提下,估算黄河下游汛期输运水量为80~120亿m3,根据实测资料估算作为黄河下游水量控制断面花园口水文站和作为河口地区水量控制断面利津水文站的非汛期生态基分别为80~100亿m3和50~60亿m3。

Based on the detailed water quality monitoring data of about 317 hydrometric stations from 1960 to 2000 and water quantity data of 20 hydrometric stations between 1919 and 2000 included in the Hydrological Yearbooks, which were all published by Yellow River Conservancy Commission, and socio-economic data related to the Yellow River, the characteristics of water quantity, major ion chemistry, organic contamination and their mechanisms, and integrated watershed management issues of the Yellow River have been systematically studied in this work.
本文在全面分析黄河流域300余水文站过去40年(1960—2000)水质资料和干支流20余水文站过去近50年(1950—2000)径流量资料的基础上,研究了:(1)、黄河水量的基本特征和近40年来的变化,重点讨论了黄河下游&断流&现象的发展及原因:(2)、黄河天然水质的基本特征、区域分布和影响因素;(3)、黄河天然水质40年来的变化趋势及原因;(4)、黄河水系氮污染和有机污染的特征、近40年来的发展,及其与社会经济发展的关系;(5)、黄河下游水质变化与水量变化的关系;以及,(6)、黄河水质水量管理中的制度安排问题。

Taking the sediment discharge of the Lijin Hydrometric Station as input, increment of area and migration of shoreline of the present subdelta as output, by using the model of linear control system which is individual input and individual output, the author built the dynamic prediction model on the development and evolution of the present subdelta, and then predicted its development and evolution, and analyzed the influences of sediment discharge of the river on its development and evolution.
首先,以黄河利津站的来沙量为输入、现行黄河亚三角洲的面积和岸线增长为输出,采用单输入、单输出的线性控制系统模型建立了现行黄河亚三角洲发育演变的动态预测模型;然后,利用该模型对现行黄河亚三角洲的发育演变进行了预测,并据此分析了黄河来沙量对黄河亚三角洲的发育演变影响。
