Mapping ecosystem services using imaging spectroscopy data

摘要

Ecosystem services (ES) generate benefits to human well-being but quality and amount of their provisioning is threatened by environmental change. Remote sensing techniques allow assessments of ES at critical scales using combinations of remotely measurable ecosystem properties. In this contribution, we use an ES assessement approach suggested by Homolova? et al. [1] and extend it to estimate ES supply continuously for a heterogenous landscape across different Earth spheres using data of the Airborne Prism Experiment (APEX) imaging spectrometer. We further suggest a conceptional framework to combine ES maps to match the needs of different stakeholders. Our results show the heterogenuous supply of agronomic ES, carbon sequestration and cultural ES within the landscape and and its different ecosystems. Our proposed ES mapping approach and the conceptual framework developed for combining ES according to stakeholder requests, provide spatially explicit information on ES across heterogeneous landscapes and can therefore improve decision-making of stakeholders.
