There have been a great changes for the land use and land cover in Tianjin Binhai new area and Caofeidian region since 1980s.Based on four years (1984,2000,2006 and 2009) Landsat images,this paper analyzed land use change characteristics for the past 26 years in the two study areas.This study adopted the maximum likelihood classification and post-classification change detection methods to monitor the land use dynamic variation characteristics,which clarified the regional differences of land use change,and provided valid decision for sustainable land use.The results indicated that:① The pond was the major land use type in the two areas,especially in Caofeidian,where the pond area covered 60%~70% of the total land area.The total land area showed an increasing trend with land reclamation from sea area since 1980s;② the reduction of cultivated area and the increasing of construction sites are the main features of land use change in two areas,especially after 2000;③ in the Binhai new area,the center of land trend for construction sites had mores towards southwest,whereas the other land use types had migrates to northeast.In Caofeidian region,the center of land use types had obvious southward trends.

Key words:  Land use classification      Change detection      Spatial-temporal analysis
