A Research and Development of Integrated Analyzing System for Accounting of Environment and Progress in Coastal Zone in China

本研究以我国沿海经济特别发达地区为研究对象，旨在建立一个具有多种环境问题求解功能和分析结果汇总、积累、编辑功能的综合环境分析系统。该系统由编辑器、显示器和求解器3个子系统组成。该编辑系统集编辑功能和数据库功能于一体，积累了与城市环境问题相关的综合数据。系统要求用户将处理后的数据集转换为系统自己描述的任意格式，然后将这些格式的数据集捕获到系统内部。例如，原始数字数据和标准化数据作为统计数据，或图像（包括GIS中的地图数据），文献信息。显示子系统使用户能够根据他们的分析对象显示他们所需的数据，例如，数字，图形，地图。求解器子系统为用户提供了 关于我们 就是用数据库中的数值数据集进行分析。该系统采用聚类分析的方法（最短最长距离法、沃德法、类平均法等）进行城市分类。用户可以在数据库中选择几个城市和一些环境评价标准，聚类分析是连续的工作，然后城市分组为具有相似的环境特征类别。他们还研究了每个群体的环境属性。这样的程序可以在这个系统上一次完成，因此，改变目标城市或环境评价标准，重新计算，重新评价的工作周期将比以往任何时候都更有效。最后，本系统的图形用户界面是在Visual Basic 6.0平台上开发的，它统一了各子系统的功能，并对系统进行了控制，从而为用户提供了一个理想的、友好的工作环境，即使用户对数据库管理的细节或GIS的复杂操作不太了解

Focusing on the especially economical developing coastal areas in China, this research aims at building a integrated environmental analyzing system that contains a solver function for several environmental problems and also aggregating, accumulating, editing function for these analyzed results. This system consists of the 3 sub-systems, editor, display, and solver. The editor sut-system is a mix of editing function and database that accumulates the composite data related with urban environmental problems. The system obligates the users to convert the handled data set as arbitrary format style which described by the system itself, then captures these ones inside. For examples, raw numerical data and standardized data as statistics, or images (include map data in GIS), literatures information are available. The display sub-system enables users to display their necessary data as according to their analysis object, ex, numerically, graph, map. The solver sub-system affords users opportunit … More ies to analyze with the numerical data set in the database. A city-classification analytical method with the cluster-analysis (shortest and longest distance method, Ward method, category-average method, so on) is available in this system. The user may select several cities and some environmental-evaluation criteria in the database, the cluster-analysis is working successively, then cities are grouped as holding similar environmental characteristics categories. They also examine the environmental properties of each group. Such a procedure could be performed at once on this system, therefore, the working cycle of changing objective cities or environmental evaluation criteria, recalculation, reevaluation will go through in more efficient way more than ever. Finally, this system's GUI that unifies each sub-system's function and operates system control is built on Visual Basic 6.0, then offers users an ideal user-friendly working environment even when they are not so aware of database managing details or GIS's rather complicate operation Less
