This awareness has led to increased study of lotic limnology, particularly with respect to the development of the potentials of river systems. The concern over deterioration of watercourses as a result of poor land utilization and their use as repositories for man‘s rejectamenta has stimulated research into the basic dynamics of the river environment and its biotic communities. Before any assessment of pollution effects can be made, or rational remedial action suggested, there must be a sound, detailed knowledge of the ‘natural‘ characteristics of regional water courses as a reference standard. This knowledge can result only from investigating the whole drainage area as a unit ecosystem (E VANS 1956) rather than just the specific conditions in the river itself (cf. SLACK 1955, HYNES 1969). Biotic data for any stream are of little value if divorced from consideration of the geology, hydrochemistry, land use and nutrient cycles of the watershed that generated | | 出版日期 | Book 1973 | | 关键词 | limnology | | 版次 | 1 | | doi | https://doi.org/10.1007/978-94-010-2692-5 | | isbn_softcover | 978-94-010-2694-9 | | isbn_ebook | 978-94-010-2692-5Series ISSN 0077-0639 Series E-ISSN 2215-1729 | | issn_series | 0077-0639 | | copyright | Dr. W.
