【摘要】：城市化進(jìn)程不斷的加快,城鎮(zhèn)人口不斷增加,帶來經(jīng)濟(jì)增長的同時,也引發(fā)了一系列生態(tài)環(huán)境問題,嚴(yán)重問題之一就是城市熱島效應(yīng)的加劇。研究城市熱島效應(yīng)的影響因素不僅對揭示城市景觀的生態(tài)過程有重要意義,而且對城市規(guī)劃、城市空間結(jié)構(gòu)的調(diào)整和城市環(huán)境的評價都有重要的指導(dǎo)意義。目前,對于城市熱環(huán)境影響因素的分析以單因子居多,缺少對于城市熱環(huán)境形成機(jī)理和地表能量過程的系統(tǒng)性研究。因此為了更充分的認(rèn)識城市熱島效應(yīng)的影響因素及影響因素之間的差異。本研究選取沿海經(jīng)濟(jì)發(fā)達(dá)地區(qū)的代表—福州市為研究區(qū),利用RS、GIS技術(shù)和城市景觀生態(tài)理論,開展了2002-2014年福州市景觀變化和生態(tài)分析、熱紅外數(shù)據(jù)的地表溫度反演及城市熱環(huán)境影響機(jī)理研究。將影響城市熱環(huán)境的因素分為土地覆蓋俐用類型、人類活動和景觀格局三大類進(jìn)行分析和研究,分析三者因素變化與城市地表溫度變化的相關(guān)關(guān)系,最終利用主成分分析方法(PCA),研究土地覆蓋/利用類型、人類活動和景觀指數(shù)對城市地表溫度影響的差異性和關(guān)系程度,分析城市熱島效應(yīng)的成因及其對生態(tài)環(huán)境的影響,提出改善城市熱環(huán)境的對策和措施。
[Abstract]:The process of urbanization continues to accelerate, the urban population continues to increase, bringing economic growth, but also caused a series of ecological environmental problems. One of the serious problems is the aggravation of urban heat island effect. The study of the influencing factors of urban heat island effect is not only important to reveal the ecological process of urban landscape, but also to urban planning. The adjustment of urban spatial structure and the evaluation of urban environment have important guiding significance. At present, the single factor is the main factor in the analysis of urban thermal environment. There is no systematic research on the formation mechanism of urban thermal environment and surface energy process. Therefore, in order to fully understand the influence factors of urban heat island effect and the difference between the influencing factors, this study selects the coastal economic development. The representative of the area-Fuzhou for the study area. The landscape change and ecological analysis of Fuzhou from 2002 to 2014 were carried out by using RS GIS technology and urban landscape ecology theory. Surface temperature inversion of thermal infrared data and study on the mechanism of urban thermal environment. The factors affecting urban thermal environment are divided into three categories: land cover, human activities and landscape pattern. The relationship between the change of three factors and the change of urban surface temperature was analyzed. Finally, the method of principal component analysis (PCA) was used to study the type of land cover / use. The difference and relationship between human activity and landscape index on urban surface temperature, the causes of urban heat island effect and its influence on ecological environment are analyzed, and the countermeasures and measures to improve urban thermal environment are put forward.
