中文摘要： 我国目前所处的快速城市化过程，在改善我们的物质生活的同时，也因强烈的人为活动造成了严重的环境污染，尤其是大气污染。城市化区域的景观格局特征是揭示景观格局与生态过程相互作用和机理，进而解决城市生态环境的关键。因此本研究选取我国典型的快速城市化区域和城市为研究区，以高、中和低分辨率遥感数据为主要数据源，以遥感信息反演、特征提取和GIS空间分析为技术手段，结合典型气象、环境和地面调查数据。从城市和区域两个尺度上,解析：1）定量化大气污染气溶胶和可吸入颗粒物（PMx）在城市和区域尺度上的时空分布格局；2）定量化城市和区域的景观格局；3）并以此为基础，探讨稳定气象条件下，城市和区域大气污染气溶胶和（PMx）与景观格局之间的关系。本研究可为量化城市化区域PMx的空间分布提供重要方法，对解析城市化区域PMx的时空分布与景观格局的相互关系，及提高城市的人居环境，促进城市的可持续发展具有重要的意义。

英文摘要： China's rapid economic growth has been accompanied by a rapid urbanization, which is essentially a geographical concentration of the population, the industry gathering as well as the change of landscape pattern. The proportion of the urbanized population in China has increased from 18% in 1978 to 47% in 2009, and it's expected that some 1 billion people will live in Chinese cities by 2030, and the urban size and urbanized region are also growing faster to suit the rapid population gathering. The rapid growth in such a short period of time has not only led to a improvement of material wealth and a higher standard of living, but has also caused severe environmental pollution, particularly air pollution in many urbanized regions of China. In this research, multi-resolution remote sensing images, meteorological records, environmental monitoring dataset, and ground survey records will be utilize at regional and urban scales (Beijing-Tianjin-Tangshan region and Beijing) 1) to quantify the spatiotemporal pattern of polluted atmosphere aerosol optical thickness and particulate matter（PMx）density; 2) to quantify the spatiotemporal pattern of landscape at both Beijing-Tianjin-Tangshan area and Beijing; and 3) to examine the effect of urban and regional landscape on atmospheric pollution. This research will contribute to t
