摘要

Long-term monitoring has a substantial history in both the biological and physicla sciences. Over time the procedures and analytical methods involved in long-term monitoring have changed to impre the quality of data, but even over short time spans, differences occur that can make direct comparison of measurement eitehr difficult or impossible. In many instances the lack of strictly defined methods or practices means that data from one project cannot be used to enhance other projects with any degree of statistical rigour. This is amply demosntrated in the field of soil classification where improvement in soil definitions, refinement of cut-off points and changes in descriptive techniques between soils is such that in many cases direct comparison of old with new data is impossible.
