My specialty is environmental green space science. We are conducting research on urban green space development for environmental restoration, disaster prevention and mitigation, and human health. Our laboratory promotes the study, planning sciences, and technical developments needed for the formation of urban environments within which human society and ecological systems can exist in harmony. To achieve these goals, our work and study methods aim at the creation of disciplines that combine sciences related to landscape and architectural planning, environmental greenery, and the preservation and promotion of health and hygiene in various ways. Our vision calls for the integration of the natural environment into all aspects of urban land use, including disaster prevention areas such flood and fire prevention, rainwater storage and circulation, and alleviation of the heat island phenomenon and the promotion of public health issues such as environmental cleanliness and recreation. Through study and experimental investigations, we will continue to advance the public interest in the functions use of natural environments. |
| Research Field(Keyword & Summary) |
- 1) Measure of heavy metal soil pollution utilized phytoremediation
During the session length, growing damage of a Chenopodium wasn't admitted. Elution amount of imitation polluted soil was below the detection limit. But the price near the initialization was detected by the Pb content of the soil. Pb absorbed amount of the Root of Chenopodium is indicated. Control was below the detection limit, 11.3mg/kg of 50mg/kg section, 53.3mg/kg of 150mg/kg section and 134.3mg/kg of 500mg/kg section in plant root analytical value by short-term（63day） growing. Next control was below the detection limit, 17.3mg/kg of 50mg/kg section, 79.7mg/kg of 150mg/kg section and 262.0mg/kg of 500mg/kg section in plant root analytical value by long-term（115day）growing. When an extended period made them grow, the Pb content increased. Pb absorbed amount of the leaf and stem of Chenopodium is indicated. Control and 50mg/kg section was below the detection limit, 21.3mg/kg of 150mg/kg section and 54.0mg/kg of 500mg/kg section in leaf and stem of plant analytical value by short-term（63day）growing. Next control and 50mg/kg section was below the detection limit, 16.0mg/kg of 150mg/kg section and 33.7mg/kg of 500mg/kg section in leaf and stem of plant analytical value by long-term（115day）growing. The difference in the contents wasn't admitted by the difference in the period of vegetation.
- 2) Study on the hot environment relaxation effect brought about by railway track greening
The surface temperature remained low in all the time zones except for the morning where the rainfall occurred, with respect to the non-greening section in the greening section. It is understood that the temperature of the greening section is also low at the height of 100 mm. Moreover, the temperature of the greening section continues to be low at night. It compared the cooling effect on the vicinity of the ground surface. Cooling time of 330 minutes at the greening section and 220 minutes at the height of 100 mm on the ground surface was
confirmed. Both the ground surface and the height of 100 mm showed that the greening section had longer cooling time than the
non-green section. It is a photograph taken by thermography. The greening plot was 7.2 degrees lower than the asphalt section and 4.4 degrees lower than the non - green section. The environmental temperature at 12 o'clock was 38.7 degrees.
