The proper hydrology model on the gird cell plays an vital role in the Distributed Hydrology Model, In this paper, It is divided two parts in vertical section, they are up-ground and under-ground relating to rainfall, air temperature, evaporation and ooze hydrological model, At the same time, I integrate all indispensable data and found two databases which are geographical information database and hydrological information database, write program using computer language—VB to simulate process of isochrones of the watershed.

创建分布式水文模型的关建是建立一个合适的基于栅格单元的水文模型，本文将栅格单元在垂直方向上分为二层，即地表层和地下层，涉及到降雨、温度、植被截留、蒸散发、下渗等水文计算模型；并综合各类相关数据，建立了地信数据库和水文数据库，通过VB编程进行等时流线模拟计算。

Based on analysis and compare of all kinds of precept-sorting of feature of plastic product for the different structural plastic product, a 3D feature library of plastic product was built on the platform by integrating Feature-Modeling technique with parametric technique. The feature schleps its information of non-geometry by database-externed technique of the entity. After building the database of plastic material, the module of choice of plastic material is developed by technology of ODBC. The plastic product can be sculpted by calling of feature of plastic product and inputting parameters interactively.

针对不同结构类型的塑件，在全面分析、比较塑件特征分类的各种方案的基础上，采用三维特征建模技术和参数化技术，建立了注塑产品的三维特征库；应用实体扩展数据库技术，使特征携带非几何信息；再在建立塑料物性数据库的基础上，采用ODBC技术，开发了塑料材料选择模块；通过塑件特征的调用和人机交互输入参数的方法进行塑件三维造型，再把塑件的三维实体和塑件的非几何信息结合起来，生成塑件全信息模型。

The innovation of this paper can be explicated as the following:First, based on the spatial concepts of cadastral feature this paper presents "general block" and "general land parcel".Second, based on "general block" and "general land parcel" this paper presents the urban and rural integrative cadastral management model, and then combined with Geodatabase it introduces design of the urban and rural integrative cadastral database, and based on this the urban and rural cadastral data can be stored in the same database by the same way.

本文的主要工作集中在以下几个方面：第一，在基于地籍要素的空间概念支持下，提出了&广义街坊&和&广义宗地&的概念；第二，在&广义街坊&和&广义宗地&概念的支持下，提出了城乡一体化的地籍管理模型，并结合Geodatabase阐述了城乡一体化地籍数据库的设计，从而真正地实现了城乡地籍数据的统一存储。

We only consider the operation system, the applied software on client machine, net and other hardware etc., When tuning the database performance with traditional way. If we only tune the database's round environment, it just respited the situation, and could not resolve the problem at all.

传统的数据库性能优化主要从操作系统、客户端应用软件程序设计、网络及其它硬件设备等方面来考虑，这种方法只是调整数据库的周边环境，只能暂时缓解问题，而不能从根本上解决问题。
