도시 수목식재와 미기후 개선의 상관성 구명

초록

The purpose of this study was to investigate the performance of porous grass block. For the investigation, Festuca arundinacea and Zoysia japonica ‘Zenith’ were planted, and the volume of evapotranspiration and remains were examined based on different materials in the water tank. In the experiment of Festuca arundinacea, the volume of water storage of treatment with perlite (10.84l/m2) was higher than that with drainage (7l/m2). The difference between the two was 3.84l/m2. The drainage treatment without water storage capacity showed the higher degree of dryness in turf grass. The volume of evapotranspiration of treatment with perlite was the highest (21.57mm/week). The volume of evapotranspiration of treatment with sand was 19.57mm/week, and with treatment with drainage was 18.24mm/week. Based on the measured volume of daily evapotranspiration of 2.60～3.08mmd-1, it was determined that the unit with water storage capacity would store water of one to two days usage compared to unite without such storage capacity. In the experiment of Zoysia japonica ‘Zenith’, the volume of water storage of treatment with perlite was 10.77l/m2 which was similar to the former experiment. The volume of evapotranspiration of treatment with perlite and sand were 21.64mm/week and 20.64mm/week, respectively.
