Base on the systematically geological investigation and study, we choose to use aremote sensing data source,the geography control data source(1:50,000relief map of Qiaojia and measured GPS ) as the data source of this research, adopt"Digital Landslide"processing image data, and carry on time-space analysiscombining geological investigation and related data. Application aerodynamicist theories, some important conclusions that obtained from the wind-tunnel experiment,and according to the time –space analysis result, we analyzed the landslide dammingmovement mechanism, presumed the movement format of this high-speed landslide,studied the formation mechanism and the movement characteristic of this landslide ,calculated it's movement equation, applied VC language to write calculationprocedure of each stage of the landslide, computed movement speed and displacement,and made sure its possible stop district.

本文在前人研究的基础上，选用遥感数据源、地理控制数据源(1：5万巧家幅地形图及实测GPS点)为本研究的数据源，采用"数字滑坡"技术处理图像数据，结合野外实地考察及相关资料对石膏地滑坡进行了时空分析；运用空气动力学理论，采用胡厚田等人在风洞实验中得出的许多重要结论，根据时空分析结果分析滑坡的运动机理，推测高速滑坡的运动模式；研究石膏地滑坡的形成机理、运动特征及运动方程，并用C++语言在VC开发环境中编写滑坡各阶段的计算程序，计算滑坡的流动速度及运动位移，确定其可能的停止区域。

A data gathering scheme MADG(movement-assisted data gathering),which makes use of the mobile base station for data collection,is presented.In this scheme,the base station moves in a stationary annularity area exploited for data buffering.The gathered data.are firstly forwarded into the buffering area and then collected by the mobile base station.

提出了一个利用移动基站协助数据收集的模式(movement-assisted data gathering，简称MADG)，它将基站移动区域设置为缓冲区，首先将数据沿最短路径传输到缓冲区内，然后在基站移动的过程中进行数据收集。

To design a basic evaluation model of attribute data in GIS, using various theory of data quality, this paper makes a deep analysis of quality control and evaluation of attribute data and brings forward a effective measure against error in attribute data. A good method is presented to improve precision of attribute data in this paper.

为了给出一个GIS属性数据质量评价的基本模型，结合已有的数据质量理论，本文对属性数据的质量控制与评价进行了深入分析与研究，给出了GIS属性数据质量控制的有效措施，并提出了提高属性数据存储、操作精度的方法。

In GIS, data quality is one of the key aspects.The Recent studies of data quality in GIS most focus in the error of spatial data. The error study on attribute data is very weak. Most studies centralize in precision analysis of attribute data from remote sensing and introduction of new method. The studies of attribute information quality stored in RDB are very weak.

近年来，GIS数据质量的研究集中在位置数据的误差上，而对属性数据误差的研究较少，多年来的研究主要集中在遥感分类属性数据的精度分析和一些新方法的引入上，而关系数据库存储的属性信息质量方面的研究相对比较薄弱。

The tradition data base Management Information System can not be made full use of, the analytical data base is hit by build-up large amount of data , the data excavates with data storehouse technology to be able to resolve this one problem very good.

传统的数据库管理信息系统不能够很好地利用、分析数据库中积累的大量数据，数据挖掘与数据仓库技术可以很好地解决这一问题。

Don not attempt to do something which you can not to do.

不要企图做那些办不到的事情。
