9、9-2:2000(E) ISO 2000 All rights reservediii Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each membe
10、r body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Elec
11、trotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting
12、. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this part of ISO 8689 may be the subject of patent rights. ISO shall not be held responsible for identifying any or al

16、nt of pollution, classification of water quality, management of water resources, habitat restoration and conservation evaluation. In many countries, biological survey results are presented in the form of a coloured map, showing the distribution of differing biological qualities1,2,3,4. Many methods
17、of measuring biological quality exist, but for running waters many countries have developed systems based on the assessment of benthic macroinvertebrate communities1,2,4,5,6.The presentation system outlined in this part of ISO 8689 relates to the assessment of biological quality based on benthic mac
18、roinvertebrates and the detection of changes in the quality of running waters using benthic macroinvertebrate communities as indicator groups.

20、thic macroinvertebrates 1Scope This part of ISO 8689 gives guidance on the presentation of biological quality data relating to running waters from surveys of benthic macroinvertebrates. The guidance is applicable to the results of surveys using standard methods of sampling and using the classificati
21、on procedures given in ISO 8689-1. It is recognized that for a complete assessment of ecological status other elements of biological quality should be assessed. NOTEAn explanation of the comparison of different indices used in the analysis of surveys of benthic macroinvertebrates is given in ISO 868

For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreemen

30、ta, from surveys of benthic macroinvertebrates in running waters, is based on the production of a colour-coded map indicating the extent of different biological qualities of the watercourses surveyed. 5Sampling Sampling for benthic macroinvertebrates shall be in accordance with ISO 5667-3, ISO 7828,
31、 ISO 8265 and ISO 9391. 6Identification Sorting and identification of animals should follow the defined procedures appropriate to the indices to be used in the classification. 7Presentation procedure 7.1Survey design For the purposes of presentation watercourses should be divided, as far as possible
32、, into reaches such that within each reach the biological quality is consistent. Within each reach a sampling site should be selected that is representative of the reach as indicated by the benthic macroinvertebrate fauna. At this site the observed data will be collected. 7.2Classification A classif
33、ication should be set up in accordance with the guidance given in ISO 8689-1. 7.3Presentation Biological quality data should be presented in the form of a map showing the reaches surveyed, coloured according to the class of the representative sampling site. The names of watercourses should be clearl
34、y marked on the map. The upstream and downstream limit of each reach should be shown on the map, together with the location of the representative sampling sites and an indication of the direction of flow. Colours and class descriptions used on the map should be in accordance with Table 1. Copyright

37、le, to excessive toxicity. The use of this colour is not to be considered part of the classification. 7.5Reaches without data To allow information to be presented on all reaches surveyed, and show the whole study area, it is important that reaches that could not be surveyed are shown on the map. The
38、se reaches should be shown as a fine black line between upstream and downstream limit markers. 7.6Map An example of a map in accordance with this part of ISO 8689 is shown in Figure 1.
