Monetary value of urban green space as an ecosystem service provider: A case study of urban runoff management in Finland

摘要: Abstract The predicted increase in the number of urban flood events can result substantial monetary losses to society. These costs may be alleviated by preserving ecosystem services, such as runoff management. We studied value this service applying replacement cost method six catchments with varying land-use intensities two cities Finland. economic analysis was based on metric data generation, provided automatic monitoring stations catchments. A hydrological model applied estimate evaporation from impervious surfaces, and simulate Our results suggest that leaving green space unconstructed significant savings. managing correlated intensity. (ESV) generally higher high intensity, low proportion space, Depending degree imperviousness, ESV ranged 90,000–270,000 € ha −1 . Further, our estimates generation are key factors for assessing ESV. study demonstrates how combination field analyses support regional planning cold climates.
