Soil Environment’s Impact on Tree Vitality within Each Space in Urban Park and Open Space

The research illuminate the relationship between soil environment and tree vitality within urban green park areas and analyze soil environment’s impact on tree vitality in each space, designating soil hardness, soil moisture degree, soil PH, K, Na, Ma, Ca quantity as independent factors after performing Pearson relation analysis. Multiple return analysis was practiced in using the analysis data. The findings are as following. The soil hardness of entrance area and facility area showing much use density is higher than that of forest area in soil environment, which means that the interference and utility pressure of soil users have effect on tree vitality. The soil factors of entrance area and facility area have been found as Mg quantity, soil hardness, and Ca quantity, while the soil factors of forest area could not be found without statistical meaningfulness. Therefore it means that in the entrance area and facility area the increasing soil hardness resulting from mineral eruption and soil user’s pressure has effect on tree vitality.
