摘要

PURPOSE: A method of establishing a riparian green zone around Nakdong river watershed is provided to secure an original function of the riparian green zone reflecting the ecological succession of riparian buffer, and to minimize the managing costs of natural resources after planting. CONSTITUTION: A riparian green zone is established in the protected lowland placed around Nakdong river watershed. Five units of pine tree, three units of ginger tree, three units of Acer pseudosieboldianum, three units of queritron, and two units of Stewartia pseudocamelia are planted per a hundred square meter of a planting area. Three units of pine tree, two units of Carpinus laxiflora Blume, three units of oriental oak, one unit of Fraxinus rhynchophylla Hance, three units of snowbell, and three units of queritron are planted per a hundred square meter of the planting area. Two units of Alnus hirsute, two units of queritron, two units of pine tree, one unit of willow tree, three units of Lindera erythrocarpa makino, three units of snowbell and two units of Cornus controversa are planted per a hundred square meter of the planting area. Two units of Celtis sinensis, two units of Platycaria Strobilacea, two units of queritron, three units of oriental oak, and two units of dentata oak are planted per a hundred square meter of the planting area. Seven units of pine tree, one unit of Quercus mongolica, two units of ginger tree, four units of queritron, three units of snowbell, three units of Lindera erythrocarpa makino, and three units of Acer pseudosieboldianum are planted per a hundred square meter of the planting area. Two units of pine tree, one unit of Carpinus laxiflora Blume, three units of queritron, one unit of Albizia julibrissin Durazz, three units of wild cherry tree, two units of Picrasma quassioides, and two units of Lindera erythrocarpa makino are planted per a hundred square meter of the planting area. Three units of queritron, three units of pine tree, three units of oriental oak, three units of snowbell, and two units of Styrax obassia are planted per a hundred square meter of the planting area. Three units of queritron, one unit of Fraxinus rhynchophylla Hance, three units of Magnolia Sieboldii, three units of Acer pseudosieboldianum, three units of Meliosma oldhamii, and three units of Acer mono Max are planted per a hundred square meter of the planting area.
