Effects of Location and Soil Characteristics on the Vegetation Structure and Tree Vitality of Urban Park and Green Open Space

This study is conducted to analyze the change of location and soil characteristics effect on the condition of urban forest in Urban Park and Green Open Space The results of this study are as fallows; 1. Soil acidity is indicated pH 3.88 in Sasang park, pH 4.38 in Hwaji park, pH 4.40 in Daeyeon park, pH 4.68 in Sanseong amusement park, pH 5.15 in Molundae amusement park. 2. Species diversity indices of indicated Sasang park 0.9932, Hwaji park 1.1975, Daeyeon park 1.2160, Sanseong amusement park 1.3080, Molundae amusement park 1.3233 is due to location and soil environment in addition to air pollution effects. 3. The vitality of Pinus thunbergii 27.5ER in Sasang park, 24.9ER in Hwaji park, 24.5ER in Daeyeon park, 23.6ER in Sanseong amusement park, 21.0ER in Molundae park. This shows that tree vitality are impacted by location and soil characteristics. On the basis of the result above, vegetation devices are suggested : 1) Robinica pseudo-acacia management, 2) removing the hazard plants; Smilax china, Humulus japonicus, Pueraria thungergiana, 3) improving soil hardness and soil acidity.
