Urban trees prevent significant runoff, offering crucial ecosystem services. Landscape structure, particularly patch shape, influences these services, guiding urban planning for better runoff reduction.
Area of Science:
- Urban Ecology
- Environmental Science
- Geographic Information Science
Background:
- Urbanization and climate change exacerbate stormwater runoff challenges.
- Trees provide vital runoff reduction ecosystem services (RRES).
- Urban landscape modifications can disrupt RRES sustainability.
Purpose of the Study:
- To analyze the relationship between landscape structure and RRES in Tabriz, Iran.
- To develop a predictive approach for RRES based on landscape patterns.
- To inform urban management strategies for sustaining RRES.
Main Methods:
- Estimating RRES using the i-Tree Eco model.
- Quantifying landscape structure using FRAGSTATS metrics (land use and cover - LULC).
- Assessing relationships via stepwise regression analysis.
Main Results:
- Urban trees in Tabriz prevented 196,854.15 m³ of runoff annually.
- Regression models showed RRES is predictable by circumscribing circle metric (r² 0.889–0.954) and shape index (r² 0.983) of LULC patches.
- LULC patch shape regularity impacts functions and RRES provision.
Conclusions:
- Landscape metrics serve as effective proxies for predicting tree-based RRES.
- Optimizing landscape metrics and management guidance can sustain urban RRES.
- Understanding landscape structure is key for effective urban runoff management.
