The quality of human life is closely related to the urban ecological situation. The research of evaluating ecological situation can provide reference for urban ecological construction and environmental protection. In order to understand and evaluate the ecological situation of Dongguan city in 2016,by using the Ecological index (EI) and Remote sensing ecological index (RSEI)based on the information source of Dongguan city's Landsat 8 satellite image in 2016,with the support of remote sensing and GIS technology. The results showed that there was no significant difference between Ecological index(EI) method's consequence and Remote sensing ecological index (RSEI) method's. So the method of Remote sensing ecological index could effectively reflect the ecological situation of Dongguan city. Dongguan city's RSEI index in 2016 was 0.584,its overall ecological environment was in good condition. The area of ecological conditions at moderate level was the large with a proportion of 54.35%. The area of good level was secondary with a proportion of 43.43%. The ecological situation was inequal in spatial distribution. The mountainous patch in the southeast region and hilly patch in south-central region were in better condition,compared with urban and water-rural areas.%人类生活质量与城市生态状况与密切相关,生态状况评价研究能为城市生态建设和环境保护提供参考.为了解东莞市的生态状况,以2016年东莞市Landsat 8卫星影像为信息源,在遥感和GIS技术支持下,用生态环境状况指数EI法和遥感生态指数RSEI法对比分析2016年东莞市的生态状况.结果表明:生态环境状况指数EI法和遥感生态指数RSEI法生态评价结果差异不显著,遥感生态指数RSEI法能有效地反映东莞市的生态状况;东莞市2016年RSEI指数为0.584,总体生态环境状况趋于良好,生态状况处于"中等"的面积比重最大,为54.35%,"良好"等级的面积次之,为43.43%;东莞市生态状况在空间分布上不均衡,东南部和中南部的山区片和丘陵片生态环境状况较好,市区片和水乡片较差.
