摘要:
随着环首都经济圈迅速的发展,该区域的生态环境退化严重。以 TM 遥感影像为主要数据源,利用遥感和地理信息系统技术,获取研究区2001年、2006年和2011年环首都经济圈的生物丰度指数、植被覆盖指数、土壤水分指数和水网密度指数,并根据生态环境质量评价模型计算生态环境质量指数,分析环首都经济圈10年间的生态环境质量变化情况。环首都经济圈各土地利用类型都出现了不同程度的增减变化。2006年相对于2001年生态环境质量整体变差,2011年相对于2006年和2001年生态环境质量整体转好,且变化的区域基本一致。生态环境质量动态评价为环首都经济圈的生态环境治理和恢复提供依据。

Abstract:
With the rapid development, the eco-environmental quality in the capital economic circle is declining. Using the remote sensing image as data sources, the biological abundance index, vegetation index, soil moisture index, and water network density index in the capital economic circle in 2001, 2006, and 2011 were obtained using the remote sensing and geographic information system technology. The ecological environment quality index was calculated using the eco-environmental quality evaluation model. The change of the ecological environment quality in the capital economic circle in 10 years was analyzed. From 2001 to 2011, the land use types in the capital economic circle appeared to be changed at different levels. The whole ecological environmental quality in 2006 was worse compared to that of 2001; however, the overall ecological environmental quality in 2011 was better than that of 2001 or 2006 and the change appeared to be in the same areas. The results of the dynamic assessment of eco-environmental quality would be used for restoration and improvement of the eco-environment in the capital economic circle.
Key words:  capital economic circle  eco-environment quality  dynamic evaluation  RS  GIS
