The major achievement of this paper is: Based on characteristics of the traffic data distribution, execute pattern recognition operations on traffic condition on two dimensions by clustering, then use BP neural network to describe and forecast traffic flow aiming at each pattern. Making use of classic flow-occupancy inverse "V" model, implement polynomial fitting using least-squares algorithm and statistics method on flow curves to detect outliers which are proved to be not accord with practice through the actual implement, then use the moving average model to recorrect the outliers and absent. Make correlation analysis on muti-direction flow queues of the intersection and ones of upriver intersections, choose flow queue with high correlation as assistant one to improve the error tolerance of the prediction system, at the same time we can use the method to give an estimation of flow in intersection with out sensors. We design and implement an SOA(Service-Oriented Architecture)-based UTDD(urban traffic data mining development) with high expansibility and performance, which implement unified management and call of the data-mining application though defining a XML-based description of data-mining process and a common interface to call data-mining process, finally we build traffic flow prediction application model on UTDD.

根据交通流量数据分布的特征，提出基于k-means的二次聚类方法，对交通流量在流量大小和时间上进行模式划分，进而对各个交通流模式进行基于BP神经网络的描述和预测，从而提高模型对流量预测的精度； 2）根据流量/时间占有率倒&V&字形曲线分布模型，提出基于最小二乘法的三次多项式曲线拟合和统计方法的异常检测方法，实际应用表明该方法能够有效识别异常数据，然后根据移动平均算法对异常数据进行修正； 3）基于序列相关性分析，分别对预测方向的交通流量数据序列、上游路口相关序列以及预测路口其它各个方向上的交通流量序列进行分析，选择相似性流量序列，作为辅助序列提供其他没有检测器路口的流量估计； 4）设计和实现了基于SOA（Service-Oriented Achitecture）的高性能、可扩展的智能交通数据挖掘系统UTDD，该系统通过定义基于XML的数据挖掘过程描述和通用的过程模型接口，实现数据挖掘应用的统一管理和调用，最后在UTDD上建立了基于路口流量预测的应用模型。

Relation Between Control in Loess Plateau and No-flow in the Yellow Rever;2. Watery changes of each year and each month induce some no-flow characters.

With respect to physiology ability character, we still can expect to grow along with the age and increase vigor and staying power ceaselessly, is not lie down is in easy chair. 1984, when Jackie Lalun already when 70 years old of advanced age, still be in surfy surface upper reaches 1.5 miles.

就生理能力而言，我们依然可以期待随年龄增长而不断增加活力与耐力，而不是躺倒在安乐椅中。1984年，当杰克·拉伦已经70岁高龄时，仍在波涛汹涌的水面上游了1.5英里。

National Oilwell Varco is a worldwide leader in the design, manufacture and sale of equipment and components used in oil and gas drilling and production, the provision of oilfield inspection and other services, and supply chain integration services to the upsteam oil and gas industry.

It is suggested that attention be given to quality of incoming water from the upper reaches while strict measures be taken to control the intensity of land exploitation in hydraulically sensitive areas and build up a ring-structure land use pattern in the waterhead region by means of land use and socio-economic driving forces.

建议在开展平原河网地区水源保护工作中，应在关注上游来水状况的同时，从土地利用及其社会经济驱动两方面控制水文敏感区域土地开发强度，构筑水源地圈层土地利用格局。

In order to calibrate the model, data of six typhoons such as the flood peak and the peak time are collected to compare with the result of the simulations. The result shows that the difference of the inflow hydrograph between them is very close. The average error of the flood peak is 5.21%. Furthermore, the error of the peak time is less than one hour but Wenny Typhoon is an exception by more than two hours. Therefore, the model could be applied to simulate the rainfall event at Shih-men watershed.

为验设模式模拟精确性，本研究以具代表性之六场台风降雨模拟，针对石门水库入流历线之观测流量与模拟值比较，结果显示模拟之水库入流历线与观测值差异不大，其尖峰流量误差绝对个平均为5.21%；另在预测洪峰到达时间方面，除温妮台风迟迟2小时外，其余均在1小时内，显示本分析模式可应用於石门水库上游集水区暴雨事件模拟。
