| 摘要: | 隨著人類的發展活動，以及經濟政策的發展，土地利用的型態從過去的農牧使用改變為現今工商使用，各地區也有不同的區位發展，進而產生不同的都市景觀。本研究以臺北市為研究對象，並依照臺北市的十二個行政分區作為樣區的劃分。
在不同的都市景觀結構下，各種土地使用類型分佈不同，產生不同都市溫度的溫差，針對臺北市的十二個行政分區做土地使用類別、土地覆蓋及地表熱演算的方式，作為景觀分類的依據，計算景觀指數。藉由景觀指數統計分析其相關的關係後，探討土地覆蓋的分佈形式與熱環境的結構型態有何種關聯。
利用遙測監視判釋方式分類土地覆蓋種類，並利用LANDSAT地表熱演算計算出地表溫度之後，依照人體舒適度間距做溫度分級，個別計算出景觀指數後，利用統計分析方式來探討地表覆蓋及熱環境之間的相互關係。
經統計分析及疊圖分析後，確認土地覆蓋的種類、分佈密度、大小、形狀及占總面積比例，均對熱環境會有一定強度的影響。而土地利用的型態不同所也會對環境產生不同的熱環境強度。
本研究成果可提供未來規畫特定的土地利用區域，藉由調整土地覆蓋的型態減緩都市熱環境的產生。
With the development of human activities, and the development of economic policy, land-use patterns changed from agriculture and animal husbandry in the past to today's commercial use also has different regional development in various regions, and different urban landscape. This research focuses on studies in Taipei City, and in accordance with the 12 administrative districts in Taipei as a division of the sample area.
Landscape structures in different cities, different types of land use distribution, resulting in a different city temperature difference, according to Taipei City's 12 administrative districts, land cover and land-use category thermal calculation of the Earth's surface, as the basis for classification of landscape, landscape index calculation. Through statistical analysis of landscape metrics after their relationship, discuss the distribution of land cover associated with the morphology of the thermal environment.
Use of telemetric monitoring interpretation mode classification of land cover types, and using LANDSAT ground thermal calculations to calculate the surface temperature, temperature classification according to human comfort spacing individual landscape after the index is calculated using statistical analysis of ways to explore the interrelationship between land cover and thermal environment. Statistical analysis and iterative analysis and validation of land cover type, density, size, shape, and proportion of total area, on the effect of thermal environment will have certain strength.
Land-use patterns in different environments may also produce a different strength of the thermal environment.
The results of this study may provide future regional planning, a specific land-use, through the adjustment of land cover type to slow down production of urban heat environment. |
