摘　　要：森林是人类赖以生存和发展的重要生态环境资源,对其时空格局进行监测和分析具有十分重要的意义。本文以全国生态文明示范区之一的江西省作为研究区,基于Google Earth Engine平台的Landsat时序数据,采用CCDC方法,对江西森林的面积和绿度变化进行了分析。其结果对森林时空格局的监测和分析具有一定的参考价值。Forests have an irreplaceable role in national economic construction and sustainable development,and it is very important to monitor and analyze changes in their spatial and temporal patterns.The continuous change detection and classification method are used to analyze the continuous change in the area and greenness of Jiangxi forests based on the Google Earth Engine platform.The results have certain reference value for monitoring and analyzing the spatio-temporal pattern of forest.
