Monitoring and analyzing of Poyang Lake wetland land use change based on RS and GIS

Abstract

Applying object-based image analysis and supervised classification to remote sensing images, this paper analyzes the land use and land cover change (LUCC) in low water period of Poyang Lake wetland from 2009 to 2014. Result shows that the wetland had restored in recent years. Area of lake and non-wetland increased remarkably due to natural factors and human activities; hydraulic projects are the main reason for the radical increase in non-wetland area from 2009 onwards; landscape indexes indicate the wetland landscape is in a lower level of fragmentation.
