On the base of Pearson correlation coefficient indicate that the connection between IBI and CQHEI is higher than IBI and ISC of Juoshuei river basin. To the section of the upper and middle reaches, we suggest choosing simple and convenient SIAM to be the standard for environment in the future. But due to the type of ecosystem has a tendency to estuary ecosystem at the lower reach of Juoshuei river basin, SIAM is more unsuitable for evaluating at the reach. The correlation between each index is not notable, so we suggest seeking other assessment method as comparative environmental standards.

由指标相关性讨论可知栖地品质与生物完整性相关性较高(r=0.649)，水质状态与生物完整性相关性则较低(r=0.267)，对於中上游河段部分，建议日后进行河川生态环境调查时可选择简便易用的SIAM模式做为标准；下游近海河段则因河川型态渐转变为河口生态系的型态，故适用於溪流生态系的SIAM在适用性上较差，各指标间相关性并不显著，建议可寻求其他评估模式做为环境品质的判断标准。

松花江大顶子山航电枢纽工程河段具有Ⅱ级台地宽、两岸堤距大、河床覆盖层厚、河床质可动性及渗透性强等特点，该河段兴建低水头航电枢纽工程其总体布置是关键，利用正态物理模型(11∶00)及遥控自航船模等研究手段，对大顶子山航电枢纽工程预可、工可、初步设计及施工图设计等阶段枢纽总体布置进行了多方案比选，提出枢纽主要建筑物布置：自右岸依次为船闸、10孔泄水闸、电站、28孔泄水闸及土坝。

The first kind is 0-equation model. It only includes mass and momentum conservation equations. Great progresses have been made in improving this model. It has successfully been applied to many natural rivers with complicated boundary geometry. The second kind is κ-ε model. The κ equation and ε equation are needed, besides mass and momentum conservation equations. Many researchers have studied the depth-averaged mathematical models of turbulence in recent years. However, the models were used mostly in regular artificial canals or natural water areas with simple boundaries.

对于宽浅型河流，采用深度平均法进行流场计算时，用得较多的有两类模型：一类是不增加任何脉动量的偏微分方程的模型，这类模型已在适体坐标下运用得较多且较成功；另一类是κ-ε二方程模型，它是近几十年来广泛应用的一类湍流模型，并发展了许多具体的形式，但大多数只对顺直河道进行了研究，对弯曲较大的河道研究不多，本文运用适体坐标，采用正交交错网格及非正交交错网格，把此模型运用到了弯曲较大的河段及具有汇流的河段，取得了较大的成功。

Based on the routine quality monitoring data of 2004 from the section of Baifa and Baise ,the present situation of water quality in Baise reach of Youjiang river is evaluated by the method of single factor pollution index, and we draw a conclusion through the trend analysis of water conditions from 1999 to 2004 using Spearman's rank correlation coefficient method.

根据百法、百色断面2004年常规水质监测资料，采用单因子污染指数法对右江百色城河段的水质现状进行分析评价，并根据该河段1999年至2004年的监测资料，利用Spearman秩相关系数法进行水质变化趋势分析。

It can be concluded that the periodic variation of tidal range and water level has both typical semidiurnal and diurnal and semi-monthly period of tide, and 64.8 d period of river runoff, which indicates that water level of the Zhujiang Delta is controlled by tide and river flow.

不同河段潮差及各分潮波振幅与径流量的大小具有明显的反相关关系，径流量越大，潮差越小，三水站潮差随流量以-0 0002的速度减小，网河区下游河段则减小得较慢。上游径流量越大，因克服径流的阻碍作用而消耗的能量越大，潮汐作用强度迅速减弱，各分潮潮波振幅和潮差沿程减小越快。

Through investigation of paleoflood deposits on the Xiaolangdi reach of the Yellow River, and by use of the field mark system for deposits judgement , identified are three types of the paleoflood deposits with four characteristics,and four geomorphologic types for the valid kind of slack water deposit.

通过分析古洪水沉积的环境及应用沉积物识别的野外特征指标体系，指出黄河小浪底河段的古洪水沉积分为 3种类型，具有 4个特点，其中赋存古洪水平流沉积的地貌类型有 4种。这一研究成果为在野外寻找及判断黄河小浪底河段的古洪水沉积提供了科学依据，对古洪水研究具有普遍指导意
