【摘要】 随着地质学信息量的不断增大以及对相关数据信息进行高效分析,计算机技术已经越来越多地应用到地质学当中。以先进的计算机软硬件、数据库技术和数学算法为手段的地质剖面数据库管理和自动成图系统,可以在实现剖面信息数据库管理基础上,根据用户需求提取相应的数据信息生成各类图件并进行相关分析,因而在地层学及相关研究中具有重要的科学和实际意义。随着实测地层剖面的逐渐增多,传统手工记录剖面数据的方式已越来越不适应研究者的保存和使用。使用数据库方法管理数据,可以保证这些数据的共享性、安全性和完整性,并极大地提高研究效率。本文基于对多年来逐渐积累的华南奥陶-志留系界线含斑脱岩地层剖面数据和现今数据库技术的分析,建立起了相关剖面的数据库,并利用ADO连接数据库,运用SQL语句初步实现了这些数据的新增、删除、修改、查询和分析等功能。传统上,地层剖面图和其他相关图件的绘制是在相关绘图软件支持下手工完成的,这样的绘制过程往往存在工作量大、时间长、精度有限等缺点,同时也不便于图件的进一步处理与分析。通过对已有技术的分析,本文进行了针对性更强的计算机程序设计和调试,初步实现了华南奥陶志留纪界线附近含斑脱岩地层剖面柱状图和斑脱岩岩层平面趋势分布图的计算机自动成图。前者是指研究者从数据库中提取华南某一剖面的数据,自动生成所需要的剖面柱状图。其技术关键主要涉及相关剖面岩性图例填充、地层系统与岩层的描述性文字处理、缓冲线、动态表格设置等;后者是指研究者能够从数据库中提取斑脱岩岩层数据,利用离散数据三角化算法、等值点追踪算法、插值和拟合等算法优化基础上的程序设计,直接实现斑脱岩岩层趋势分布等值线图的自动绘制。整个系统是在Windows系统平台下,基于Visual C++开发工具,以C++为语言进行开发工作的;同时采用GUI的设计原则和方法,较好的实现了交互式的系统界面。更多还原

【Abstract】 Being on the increase of the geological data and for the various efficient analyses of them, computer technology is more and more applying to geology. Geological section database and graph-auto-making system with the base of the advanced computer software, hardware, database technology and arithmetic, make the illustration of the different graphs and other works much more quickly and conveniently, it is more and more important in stratigraphy and the relevant researches.Considering the large number of the geological stratum sections, traditional method to note data by hand put the researchers to extreme inconvenience in the coming works. Oppositely, it can assure that they are shared, security and integrity, and raise research efficiency to manage the data with a computer database. The present research has tried to make the database management preliminarily of the K-bentonites-bearing sections (Late Ordovician-Early Silurian) in south China, which can add, delete, change, inquire and analyses about the data with the ADO technology and the SQL.Traditionally, the stratum section columns and other graphs are drawn on the graph-software manually. It is a hard work for everyone that needs much time, not very precise and bad for farther analyses. The present paper reports the initial achievements on the graphs-auto-making techniques of the K-bentonites-bearing sections (Late Ordovician-Early Silurian) and contour plot of the K-bentonites potential distribution in south China by design and debugging of the computer programs. The former one is the stratum section column auto-making program that can draw any section by the computer itself with the relevant data from the database of the K-bentonites in south China mentioned-above.. The key technologies mainly refer on the symbols and patterns filling of the lithological characteristics, the description of the stratigraphic chart systems and the lithological layers, the setting更多还原
