METHODS OF RIPARIAN GREENSPACE ESTABLISHMENT FOR GEUM RIVER WATERSHED THROUGH ECOLOGICAL PLANTING MODEL AND TECHNIQUE

摘要

PURPOSE: A method of establishing a riparian green zone around watershed is provided to decide a species composition and the density of planting appropriate for a growth environment, and directly establish an ecological plant assembled with multilayer planting. CONSTITUTION: A riparian green zone is established in the protected lowland placed around Keum river watershed. Four units of pine tree, one unit of elm tree, one unit of snowbell, three units of Sapium japonicum, two units of Lindera erythrocarpa makino, and two units of Carpinus laxiflora Blume are planted are planted per a hundred square meter of a planting area. Two units of pine tree, two units of Carpinus laxiflora Blume, one unit of snowbell, one unit of zelkova, one unit of snowbell, one unit of queritron, and one unit of Acer pseudosieboldianum are planted per a hundred square meter of the planting area. One unit of white oak, one unit of Acer mono Max, two units of snowbell, two units of Lindera erythrocapa makino, two units of styrax obassia, two units of Acer pseudosie boldianum, two units of wild pear tree, and one unit of Sapium japoricum are planted per a hundred square meter of the planting area. Two units of Cornus controversa, one unit of Acer mono Max, one unit of Albizia julibrissin Durazz, two units of snowbell, two units of Lindera erythrocarpa makino, two units of Aphananthe aspera, and two units of Acer pseudosieboldianum are planted per a hundred square meter of the planting area. Five units of pine tree, two unit of Carpinus laxiflora Blume, one unit of oriental oak, three units of snowbell, three units of Acer pseudosieboldianum, three units of styrax obassia, and three units of Lindera erythrocarpa makino are planted per a hundred square meter of the planting area. Three units of pine tree, two units of oriental oak, two units of Lindera erythrocarpa makino, four units of Sapium japonicum, four units of fraxinus sieboldiana, two units of snowbell, two units of Carpinus laxiflora Blume, two units of Quercus acutissima Carruth, and two units of white oak are planted per a hundred square meter of the planting area. One unit of queritron, one unit of oriental oak, two units of Cornus controversa, two units of styrax obassia, two units of Acer mono Max, and two units of snowbell are planted per a hundred square meter of the planting area.
