摘要:
 为了解珠江三角洲城市群的生态状况，基于珠江三角洲城市群2006年和2016年的Landsat卫星影像，对比、分析EI法与RSEI法对珠江三角洲城市群生态状况的评价，分析珠江三角洲城市群的生态状况及动态变化。结果表明，EI法与RSEI法评价珠江三角洲城市群生态状况结果差异不明显，RSEI法能有效反映城市群的生态状况。2006年珠江三角洲城市群生态状况主要受湿度指标影响，2016年生态状况主要受绿度指标影响。2006年珠江三角洲城市群生态状况以良为主，2016年以良和优为主。2006-2016年，珠江三角洲城市群生态状况不断改善，有向优、良转变的趋势，生态状况改善的地区主要分布在城市群边缘、植被盖度较高或高海拔的地区，占总面积的48.71%；生态状况变差的地区主要分布在城市群中部发展较快的、密集居民区和工业基地等人类活动频繁的地区，占总面积的6.42%。
Abstract:
 Since the reform and opening up,the Pearl River Delta Urban Agglomeration (PRDUA) has developed rapidly,and the negative environmental effects have changed constantly.Based on the Landsat satellite images of the PRDUA in 2006 and 2016,this paper compared and analyzed the EI (ecological index) method and RSEI (remote sensing ecological index) method to evaluate the ecological status of PRDUA,and analyzed the ecological status and dynamic changes.The results showed that there was no obvious difference between the results of the EI method and the RSEI method,and the RSEI method could effectively reflect the ecological status of the PRDUA.In 2006,the ecological status of the PRDUA was mainly affected by the humidity index,while in 2016,by the greenness index.In 2006,the ecological status of the PRDUA was good,and 2016 it was dominated by good and excellent.From 2006 to 2016,the ecological status of PRDUA had been constantly improved,with the phenomenon of excellent and good transformation.The areas with improved ecological status were mainly distributed in the edges of the urban agglomeration,the high vegetation coverage or high altitude,accounting for 48.71% of the total area.The areas with deteriorated ecological status were mainly distributed in areas with rapid human activities such as densely populated areas and industrial bases in the middle of the urban agglomeration,accounting for 6.42% of the total area.
