Abstract:	本研究之目的為從土地覆蓋變遷的角度切入，探討都市建地、綠地等土地覆蓋特性是否在空間、時間上與都市相關之公衛問題具有關連性。具體來說，本研究將透過台灣都會地區的實證研究，分析都市化進程與空氣汙染(PM2.5)以及都市熱島等問題之關係。依據內政部人口統計資料顯示，台灣都市化程度已高達80%。高能源機具的使用集中於都會區，使得都市熱島效應明顯，主要產生的問題為降低空氣品質並加大極端熱事件的影響，讓都市居民面臨更高的健康風險。過去不少研究已說明空氣汙染以及都市熱島效應此二者與土地覆蓋的類型與特性(如破碎度)具有高度關聯性，本計畫將應用土地利用模式，配合歷史衛星影像、土地利用調查、歷年各項社經發展等統計資料進行台灣六都之都市化的模式建構；同時分析都市建地、綠地等土地類別在面積、空間分布結構的變化歷程，並與空氣污染、熱島問題等資料進行空間與時間上的關聯，以探索、評估都市化過程如何形朔、影響都市之公衛問題，並能配合土地利用模式進行相關都市空氣污染以及熱島效應的情境預測。 ;Analyzing the correlation between land-use and land-cover change and public health issues in space and time domain is the main focus of this study. Specifically, this study will examine the relationships between historical land-cover change in major cities of Taiwan and their intensified conditions of air pollution and urban heat islands. Government reports and statistics have shown that the increase of residents of urban areas in Taiwan has a significant impact to the living environment, including the extension of impervious area and fragmentation of green lands. This change may cause a considerable risk for public health due to urbanization and industrialization which have been creating multi-driving factors to air pollution, urban heat islands, and other public health problems. To analysis their correlation in the time period of 2000 to 2017, satellite imagery will be used to map the historical landcover of six major cities in Taiwan, and then embedded into the development of a landcover change model for future projection. We expect the study results could be referred to authorities as useful guidelines when making policies for public health.
