Based on the water resources survey of Shanghai in 1999 and the 1:50 000 color infrared aerial photos obtained in early 2000, a case study of the upper Huangpu River was carried out. The exponential method, pair-sample t test, and remote sensing analysis are used to analyze water environmental characteristics and land use pattern in the river network plain. In order to explore response of water quality in the waterhead region to the changes in land use and its driving force, five land use patterns are selected and a new type of exponential is designed.

以黄浦江上游水源地为例，利用1999年上海水资源普查数据及2000年初成像的上海市1：50000彩红外航空像片，采用GIS空间分析技术、灰色关联分析技术，划分土地利用样带，设计水质改善指数，探讨平原河网地区水环境质量对土地利用结构的响应，以及水源水质对土地利用变化驱动力的响应。

And the equations are solved coupling iteratively whith PCG method for Laplace equation and Gauss—Seidel method for convective equation.So the distribution of piezometric tube waterhead and saturation can be obtained.And the seepace free surface will be captured automatically according to the distribution of saturation with the concept of VOF.

分别对饱和区的拉普拉斯方程采用预处理共轭梯度法、非饱和区的对流方程采用Gauss—Seidel方法进行耦合迭代求解，得到渗流场的测压管水头分布和饱和度分布，并引入VOF的概念，由饱和度的分布自动扑捉渗流自由面。

你的那一套办法对他来说没用。

Results Meliorative group : 1 case （ 2.5%） died, and 2 cases （ 5.0%） occurred with obstructive waterhead.

结果改良组1例（2.5％）死亡，2例（5.0％）发生梗阻性脑积水；传统组5例（12.5％）死亡，6例（15.0％）发生梗阻性脑积水。

It has important effects for the stability of water conservancy building,the using of groundwater resource,the pollution controlling,the exploitation of rock oil and natural gas.And the needs of projects for those fields are increasing home and abroad.So the research of seepage flow becomes focuse.In this article,a saturated and unsaturated seepage model has been established which includes double variables:piezometric tube waterhead and saturation.

渗流现象是多孔介质中普遍客观存在的运动规律，其对水工建筑物稳定性、地下水资源利用、污染控制、石油天然气开采等工程问题均具有重要的影响，随着国内外在上述领域中工程需求的增加，渗流研究日益成为热点问题。
