| 摘要: | 研究期間：10108~10207;In recent decades, the fast-growing industrial and commercial development in Taiwan, based on large-scale industrialization and urbanization, rapid change of land cover and global warming effects, leads to the changes of surrounding environment, such as landscape, climate, temperature, hydrology and humanity environment, etc. Among them, the land cover changes in the Taoyuan area is fast; the variation is more obvious especially in northern Taoyuan area, including the expansion of urban areas, reduction of the number of farmlands and ponds. However, urban expansion is involved in population density and lifestyle, but the area of agricultural land and the number of ponds is directly affected by urban development while the regional land cover change indirectly affects the thermal environmental of the overall area. Therefore, this project aims to explore the relationship between the regional thermal environmental in Taoyuan area (urban heat island, heat sink effect and temperature change) and the land cover change (number of ponds, area of agricultural land and urban expansion). It will combine the aerospace technology and the remote sensing technology and will apply a continuous multi-period and wide-range data of satellite observations in the three-year research, and lead in the technologies of spatial information, theory analysis and strategy management of Taiwan Global Earth Observation System of Systems (TGEOSS). By making use of the images of different periods to explore the changing relationship among land covers, to quantify the temperature changes of the whole area, and to simulate the effect of different changes of land cover on the regional environment, this project will contribute to understand the extent of land cover change of the overall area in order to plan priority level of retaining important land cover. Such research data and achievements, in addition to mutually support the various sub-projects, can provide a whole integration for the policy recommendations to promote in other regions of Taiwan in the future. |
