Recognition of environmental importance on soils in urban area is insufficient in Japan due to her policies. The policies only highlight the improvement of production capacities of agricultural soils and environmental conservation of agricultural areas. Therefore, it is essentially needed to provide information on characteristics and function of urban soils for urban planners to improve their planning technique supported by scientific findings. The main purpose of this study is to discuss the methodology for evaluation of potential affluence of urban soils by adopting biodiversity and grading method. For this purpose, parks, field athletic areas and university campus in Kanagawa Prefecture were investigated. Soil samples were collected from these areas to examine soil pH, total carbon content, CN ratio, water content, man-made rubbles and soil animal composition. Analysis results together with soil compactness investigated in each field indicated significant difference among the following terrains: bare land, grassland, shrub and forest. It proved that soil animal biodiversity and direction of soil transition were regulated by the condition of vegetation management (by mowing and trimming) and nature of soil at initial stage.
