摘要
利用北京一号小卫星数据和Landsat TM/ETM+数据进行生态环境效应遥感分析。首先,对3期遥感影像进行解译得到土地利用状况图,并分析了其变化情况;然后,应用GIS技术,结合景观生态学的方法分析了景观结构变化;利用RS技术分析了密云县植被及地表温度;最后,分析了不同土地利用和不同生态区划的NDVI和地表温度的变化特点。综合上面的分析,指出了RS与GIS方法在城市生态环境分析方面的优势。
Using Landsat and Beijing - 1 satellite images, the authors obtained several eco - environment factors with the help of RS and GIS technologies. This paper has dealt with the land use maps of three terms and, on the basis of land use, analyzed vegetation coverage and landscape indexes to disclose the variation. In addition, land surface temperature was calculated from the ETM ^＋ image of 1999. The above factors detected in 1999 and their relationships are also discussed for different ecological regions.
