2.1. Multiple benefits of blue-green spaces
Urban green space and water bodies have multiple functions and can meet
the diverse requirements of urban development, such as human-centered,
organism-centered, and economic construction-centered functions. Among
these functions, anthropocentric functions mainly include health
functions, entertainment functions, etc. Organism-centered functions are
mainly ecological service functions, such as habitat provision, climate
control, and pollution control(Rehachova and Pauditsova, 2004). Economic
construction-centered functions include increasing urban and resident
wealth (Chiesura, 2004). These functions are classified into three
aspects: ecological, mental health, and economic benefits.
