선진 하천환경 평가체계의 사례검토

This study was carried out to suggest principles & guidelines necessary for setting up of the assessment system applied in Koreanstream. The work was based on the review and discussion of advanced stream assessment techniques and its adjustment for Koreanstream condition and management status. The results obtained from this study were summarized as follows: Firstly, stream assess-ment system has been developed from the fact that geomorphological structures and chemical qualities forming stream system in thehierarchy, were closely correlated to the biological diversity through temporal and spatial scales. Therefore, Korean stream assess-ment system must be developed with a sufficient consideration on the characteristics of stream conditions as well as actual status ofstream management. The other side, those advanced and standardized assessment system, which has been originated from a longexperienced lessons on stream management, interdisciplinary knowledge and techniques, represented much logic consistence in viewof basic components such as aims for assessment, establishment of assesment indicators and criteria, selection of reference condi-tions. Accordingly, our assessment system must be also progressed towards scientifically oriented and integrated system which reflectsour real stream surroundings and also includes some principles and process and techniques reviewed in advanced system.
