摘 要:以2006年TM、SPOT4及QuickBird遥感影像为信息源,在地理信息系统与遥感技术的支持下,结合野外调查及其它辅助数据,运用生态环境状况评价技术规范,对北京市2006年的生态环境质量进行评价,并对2000年与2006年北京市生态环境变化进行动态分析。结果表明:2006年北京市生态环境质量评价指数为59.707,处于良好等级;2000-2006年间,北京全市生态环境状况稳定保持在“良”的状态,总体变化不大,但北京市耕地面积减少了339.09 km^2,城镇建设用地增加了285.24 km2,水域面积减少了118.98 km^2,其主要原因是降水量的减少、城市化扩张以及人为因素影响。Supported by GIS and RS technology and combined with field investigation and other accessory data, the authors evaluated the ecological environment quality of Beijing by using remote sense images of TM, SPOT 4, QuickBird and the Ecological Environment Quality Evaluation Criteria. The monitored variations of Beijing' s ecological environment from 2000 to 2006 were also analyzed. quality evaluation index of 2006 was 59. 707, remaining in the The results show that the ecological environment rank of" fine". From 2000 to 2006, the ecological environment was steadily in the rank of" fine". Nevertheless, the area of plantation was decreased by 339,. 09 km2, the area of town building was increased by 285.24 km2 and the area of water was declined by 118.98 km2, which may be attributed to such factors as reduction of rainfall, urbanization and human activity.
