摘要：Recent scientific developments are advancing to link land use and land cover (LULC) changewith ecosystem service (ES) potentials. Such links within peri-urban ecosystems are scantydue to methodological and expertise challenge, and data limitation. The study applies the ‘ESmatrix approach’ to spatially display potentials for regulating ES in mainly overlooked datascarce peri-urban areas, whereby LULC classes and qualitative ES values are the main datainputs. The LULC maps are based on LANDSAT satellite images from the years 1990, 2000 and2010. ES potentials were assessed qualitatively on a relative scale ranging between 0 and 5 byuse of interview data from local people. Results show that with exception of settlements, thearea for all LULC classes decreased between 1990 and 2010. The ‘matrix approach’ successfully generated ES potential maps for the different LULC classes. Grasslands, forests andwetlands have comparatively high potentials for regulating ES, whereas settlements and‘otherlands’ showed lower potentials. The main uncertainties of the study relate to studyarea selection, data accuracy and reliability, and ‘matrix approach’ adaptability. Resultsindicate that the potential of the area to provide regulating ES is declining over time. Torealize suitable and reliable results, it is necessary to conduct data accuracy-check during andafter the fieldwork exercise.
