Abstract:: Taking Wuchuan as the study area,using ArcGIS and Fragstats software to 1990,2000 and 2007 3 TM remote sensing image as based data sources,to establish the land use remote sensing image interpretation signs,to get all types of property landscape data and graphics data,a spatial information database,the dynamic landscape pattern change of Wuchuan county in recent 17 years were studied.The results showed that,farmland,woodland and grassland in the entire land landscape were relatively larger,the heterogeneity of farmland was the highest,that of residential and construction land were smaller,waters were minimum.Forest area increased year by year,the degree of fragmentation decreased,connectivity gradually enhanced,the ecological environment construction effect of Wuchuan county obviously was obvious under in returning farmland to forest and the role of Beijing and Tianjin sandstorm source control projects.Area of unused land was mainly sand and saline showed a continuous distribution of a large area,indicating that the area of land desertification situation was still very serious,we must continue to uphold the policy of returning farmland to forest and grassland,improve the ecological environment.
