Profile My speciality is urban ecological planning, in which urban ecology and ecological planning are integrated. In particular, I am conducting research on the planning, evaluation, and management of green infrastructure that balances the water cycle and the ecosystem, targeting watersheds and catchment areas. By integrating GIS and remote sensing, we analyze water flow, topography, and the structure and function of ecosystems.We also analyze the function and structure of green spaces in collaboration with the government and local residents for optimal green space layout and ecosystem management. Recently, we are also focusing on collaboration with companies and citizens for the maintenance of green infrastructure and the practice of citizen science.
Research Field(Keyword & Summary)
  1. (1) Green infrastructure planning

    We analyze and visualize the multifaceted environmental functions of urban green spaces such as urban roadside trees, parks, and private green spaces. In particular, we will analyze the difference in water infiltration and the effect of soil structure according to the arrangement and structure of green spaces, and clarify the conditions of green infrastructure that contribute to the water cycle and ecosystem.

  2. (2) Urban ecological network

    We are developing technologies to quantitatively evaluate and visualize urban ecosystem networks. We will compare the effects of greening on the ecosystem by simulation, and clarify the conditions for more effective ecosystem network formation and the conditions for conservation management.

  3. (3) Landscape management

    We will evaluate land use and landscape to achieve both ecosystem and disaster prevention in the basin. Recently, we have been focusing on research and analysis on green space management in catchment areas in order to achieve both urban flood mitigation and urban ecosystem networks.
