碩士 === 國立臺北大學 === 都市計劃研究所 === 96 === The attention of global environmental change has triggered the research on urbanization and ecosystem change in peri-urban areas. Since the establishment of “International Geosphere Biosphere Program—A Study of Global Changes” in 1986, the recently launched “Global Land Project (GLP)” identified many issues on the implications of land use change and how ecosystem services are linked to human well-being. Taiwan’s natural environment is dominated by sub-tropical island ecosystem, which is very sensitive to climatic change. And, the urban sprawl in the peri-urban areas of major cities in Taiwan has already threatened the cities’ life-supporting environments. To study the impact of land use change in the Taipei-Taoyuan’s peri-urban areas on their ecosystem services during 1971-2006, this study employed ecological energetic analysis to valuate the worth of natural environment to the socioeconomic system in the region. The results of emergy syntheses indicate that the agricultural area in the study region played important food provisioning services before the effect of urbanization on peri-urban land use. The emergy synthesis of 2006 also shows that mountainous forest provides services of water supply and water regulation services to urban system. The pattern recognition of ecosystem components via impact matrix shows that the water contained in forest and upstream water resources are correlated with the water regulation; they are the most critical components of the study region.
