1.1 本指南涵盖了根据研究目标、探索性数据分析和空间变异分析选择适当克里格方法的建议。 1.2 本指南考虑了常用的克里格法，包括普通克里格法、简单克里格法、对数正态克里格法、通用克里格法和指示克里格法。不讨论多元、时空和其他不太常用的克里格方法；然而，这并不是为了反映对这些方法有效性的任何判断。 1.3 本指南描述了克里格方法不适用的条件以及应使用地质统计模拟方法的条件。 1.4 本指南不讨论克里格的非地统计学替代方法，例如样条或反距离技术。 1.5 本指南不讨论克里格法的基本原理。 地质统计学和克里格法的介绍可以在许多文本中找到，包括参考文献 ( 1- 3. ) . 2. 参考文献对克里格方法进行了综述。 ( 4. ) . 1.6 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.7 本指南提供了有组织的信息收集或一系列选项，并不推荐具体的行动方案。本文件不能取代教育或经验，应与专业判断一起使用。并非本指南的所有方面都适用于所有情况。本ASTM标准不代表或取代必须根据其判断给定专业服务的充分性的谨慎标准，也不应在不考虑项目的许多独特方面的情况下应用本文件。 本文件标题中的“标准”一词仅表示该文件已通过ASTM共识程序获得批准。 1.8 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 4.1 本指南旨在鼓励在环境、岩土和水文地质现场调查中应用克里格方法的一致性和彻底性。 4.2 本指南可用于协助进行克里格研究的人员，或为可能正在审查或审计该研究的合格非参与者解释程序。 4.3 本指南鼓励使用特定于现场的信息来选择适当的克里格方法；然而，任何克里格方法的选择都无法改善或补偿数据质量、采样密度和场地覆盖率。 4.4 本指南描述了推荐使用克里格法或特定克里格法的条件。然而，如果没有遇到所述条件，这些方法不一定不合适。 4.5 本指南应与指南一起使用 D5549 , D5922 和 D5924 .

1.1 This guide covers recommendations for selecting appropriate kriging methods based on study objectives, exploratory data analysis, and analysis of spatial variation. 1.2 This guide considers commonly used forms of kriging, including ordinary kriging, simple kriging, lognormal kriging, universal kriging, and indicator kriging. Multivariate, space-time, and other less-frequently used kriging methods are not discussed; however, this is not intended to reflect any judgement as to the validity of these methods. 1.3 This guide describes conditions for which kriging methods are not appropriate and for which geostatistical simulations approaches should be used. 1.4 This guide does not discuss non-geostatistical alternatives to kriging, such as splines or inverse-distance techniques. 1.5 This guide does not discuss the basic principles of kriging. Introductions to geostatistics and kriging may be found in numerous texts including Refs ( 1- 3 ) . 2 A review of kriging methods is given in Ref. ( 4 ) . 1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.7 This guide offers an organized collection of information or a series of options and does not recommend a specific course of action. This document cannot replace education or experience and should be used in conjunction with professional judgment. Not all aspects of this guide may be applicable in all circumstances. This ASTM standard is not intended to represent or replace the standard of care by which the adequacy of a given professional service must be judged, nor should this document be applied without consideration of a project's many unique aspects. The word “Standard” in the title of this document means only that the document has been approved through the ASTM consensus process. 1.8 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 4.1 This guide is intended to encourage consistency and thoroughness in the application of kriging methods to environmental, geotechnical, and hydrogeological site investigations. 4.2 This guide may be used to assist those performing a kriging study or as an explanation of procedures for qualified nonparticipants that may be reviewing or auditing the study. 4.3 This guide encourages the use of site-specific information for the selection of an appropriate kriging method; however, the quality of data, the sampling density, and site coverage cannot be improved or compensated by any choice of kriging method. 4.4 This guide describes conditions for which kriging or particular kriging methods are recommended. However, these methods are not necessarily inappropriate if the stated conditions are not encountered. 4.5 This guide should be used in conjunction with Guides D5549 , D5922 , and D5924 .
