This document introduces the EPPS (Ecosystem Properties, Potentials, and Services) conceptual framework. It discusses how ecosystem properties describe the biophysical structures and processes of ecosystems. Ecosystem potentials are then derived from the properties to represent the potential for ecosystems to provide services. Finally, ecosystem services are defined as the benefits ecosystems provide to humans. The framework aims to better integrate ecosystem services into spatial planning by linking potentials and services. The document then applies the EPPS framework to analyze urban ecosystems, their properties, potentials, and services.
