【摘要】 本文以地理信息系统(GIS)理论和随机场理论为指导，进行了基于随机场的地理信息系统的结构与功能设计。研究内容分以下两个方面： 首先以某场地的岩土工程勘察信息为研究对象，通过计算其数字特征与检验其平稳性和各态历经性，证明了岩土参数具有平稳性随机场的特性。故可将士体看作齐次平稳随机场。在对其土性相关距离研究的基础上，分别就岩土参数的预测进行了较深入的探讨。 其次通过对GIS的目标、任务、用户需求和数据的分析，进行数据库的设计，经数据分类、编码等数据预处理，建立了一个包含文本、图形、表格等数据类型的数据库。运用GIS系统的空间分析和辅助决策功能，建立专业模块，在实现对原有地质资料信息管理的同时，可以利用这些信息资源对拟建区域的岩土参数进行预测。 最后以保定市岩土工程勘察地理信息系统为例，实现了对随机场与地理信息系统相结合的研制与开发。更多还原

【Abstract】 According to the geographic information system(GIS) and the the random field, this paper studied designing the structure and function on the geography information system based on the random field of soil parameter. The study divides below two aspect:First, that the soil parameter has the characteristic of stationary random fields is proved according to calculating its digital feature and testing whether this random fields is a stationary process and whether it is ergodic based on the geographical information of one area in Baoding. So the soil parameter is able to be looked as the stationary random field. The prediction of the soil parameter is discussed in-depth on the basis of studying the correlation distance.Second, the concept and logic of the database was designed by analyzing the object and mission of the GIS, the user’s demand and the source of data. After classifying the data and coding, a database including such data types as text, figures and tables was built. The professional module is established by the function of dimensional analysis and assistant decision-making of GIS, so while the useful geological information is managed, soil parameter of the unbuilt areas is predicted using these geological information.Last, given the Reconnaissance-GIS of Baoding for example, the development of the random and the GIS are combined is realized.更多还原
