Living with water linking spatial planning: A study in Tseng-Wen River Basin

The purpose of this article lies living with water linking spatial planning, how to analyses the interests of water environmental in Ecoregions land use strategies, also by using hydrology toolset and explore spatial analysis, a non-parametric benchmarking technique to assess water environment from land-using point of view. This study adopted Tseng-Wen River in Tainan as the study area. The analytical results demonstrated that changing of agricultural land-using and Land for Irrigation and Drainage into others have been decreased 5,658 ha for water environment efficiency and caused loss functions of water retention. As to the space, both upstream and downstream are the most serious affected areas which indicated that hilly land development influences the water runoff. This article further uses Ecoregions infiltration basin, percolation trench, and bioretention to construct water environment system's initial form. Those findings may serve as basis for establishing future land-use indicators and decision-making references for concerned government agencies.
