| Abstract |
This study was carried out for the purpose of creationg a restoration plan to improve ecological quality of Changwon and Nam streams. Based upon the results of comprehensive diagnostic assessment, restoration priority was given in the upstream reach, where conservation status is relatively superior. Restoration level was usually determined to practice active restoration as conservation, and the states of both Changwon and Nam streams were not so good. Restoration plans, by reach, were classified into “upstream”, “midstream”, and “downstream” were suggested in both terms of horizontal section frame and vegetation based on the result of diagnostic assessment and the reference information. “Upstream”, “mid-stream”, and “downstream” of Changwon and Nam streams were classified into “small-gravel- mountainous”, “small-sand-plain”, and “small-clay-plain streams”, respectively (based on scale, and substrate and slope of river bed). The spatial arrangement of vegetation was laid out in diagram form by reflecting micro-topography and the water level of the horizontal section of river. Information regarding species composition was recommended as dominant species, which appear frequently in three vegetation zones composed of herbaceous plant, shrubs and tree and sub-tree dominated zones divided by reflecting disturbance regime, depending on position on the horizontal section of river. Moreover, there have been prepared not only plans to improve the terrestrial ecosystems around the streams but also plans to create ecological networks, which can serve to improve ecological quality of the whole regional environment by serving to connect streams and terrestrial ecosystems, a process probably necessary and definitely recommended to realize true (genuine) restoration. Plans for ecological park and networks were prepared by mimicking species composition of Alnus japanica community, Zelkova serrata community, Carpinus laxiflora community, Quercus aliena community, and Q. serrata community. |
