Thus the conventional method for the delineation of hydrologically homogeneous regions is not an excellent method.

因此传统水文均一区的划分方法并不是一个良好的方法。

For facilitating the delineation of hydrologically homogeneous regions, the purpose of this thesis is to develop a method that combines cluster analysis and discrimination analysis.

本文的目的在於发展一整合群集分析及识别分析的方法，以改进水文均一区划分的方法。

Therefore, the substance of the conventional method for the delineation of hydrologically homogeneous regions is first described.

本论文首先说明划分水文均一区的本质。

The delineation of hydrologically homogeneous regions is the major task.

其中，水文均一区的划分是区域化中极为重要的工作。

The conventional method for the delineation of hydrologically homogeneous regions consists of three complicated statistical techniques (principal component analysis, cluster analysis, and discrimination analysis).

过去，水文均一区的划分是透过三种复杂的统计技术（包含主成分分析、群集分析及识别分析）的结合而完成。

Result showed that using digital map and ANUDEM software can generate hydrologically correct DEM of meso-scale in the loess hilly region.

随着科学技术的发展，虽然DEM可以通过遥感数据直接提取，但迄今为止，最为成熟、经济可行的方法是利用数字地形图插值建立DEM。

Among these three methods, principal component analysis is not necessary; a large amount of severe problems (such as the determination of the number of clusters) encountered in the delineation of hydrologically homogeneous regions arise in conventional clustering methods and the employ of discrimination analysis is not intuitional.

在这三种统计技术中，主成分分析并非划分水文均一区必要的步骤；大部份关於水文均一区的划分的问题则存在於传统的群集分析方法中；而识别分析在水文均一区划分中的用法则并不直觉。

Result showed that using digital map and ANUDEM software can generate hydrologically correct DEM of mesoscale in the loess hilly region.

基于极限平衡理论，综合考虑土质边坡上林木根系的力学加固土壤作用和水文增加基质吸力效应，以及林木附加自重对边坡稳定的负面效应，建立了一个用来评价造林土质边坡浅层平面滑坡的分析模型。

The first is how to adequately define topographicst ructure morphol- ogically or hydrologically, and the second is how to design algorithms for the defined topographic structure. From the improving the approachs of the filling depressions and making gradient of plain in DEM, the extraction efficiency and result accuracy are better than existing methods and better fit to deal with the mass data of DEM.

通过对DEM中的洼地和平原区域处理算法的改进，使效率和结果准确性等方面都有了明显的改进，从而更加适合于对大范围流域的DEM数据进行处理与信息提取。
