An Analysis and Simulation of Land Use and Landscape Pattern Change in Wuhan City

Applying remote sensing and GIS tools,this paper uses two Landsat TM images acquired respectively in 1994 and 2005 to analyze changes of land use and landscape pattern in Wuhan City,and then integrates the Markov process with cellular automata(CA) model to simulate the scenarios of land use in 2016.The results show that the predominant land use types were cultivated land, water-body,and land for construction.From 1994 to 2005,the investigated area experienced notable increment of land for construction and forest land and a great loss of cultivated land,grassland,and water-body,that most of the reduced cultivated land was used for construction,and that the reduced water-body,grassland and forest land were mainly converted into cultivated land.During the same period,the indices of landscape fragmentation and dominance increased while the indices of diversity and evenness slightly decreased. By 2016,cultivated land and water-body would be reduced greatly while land for construction and forest land would still increase.
