Dynamic Change and Prediction of Land Use and Vegetation Coverage at Zhuozi County in Inner Mongolia

Taking Zhuozi county the typical county of returning farmland to forest in Inner Mongolia as the research object,according to the TM images and other auxiliary materials of the two periods in 1999 and 2007,this paper analyzed the change of land use,regional difference and transformation between various types,and used markov model to predict the dynamic changing trend of the land use in 2015.The results showed that in the Zhuozi county of Inner Mongolia in the period of 1999-2007,due to the implementation of the project of returning farmland to forest,the area of forest land and grassland was greatly increased respectively,while the area of cultivated land and waters was greatly reduced respectively.Accordingly,it can be said that the cultivated land,forest land and grassland were the dominant types of land use change in this area,and they had widely mutual transformation with other types of land use.By 2015,the area of grassland will be increased continuously,while that of the forest land and cultivated land will be reduced.Forest land,cultivated land and grassland are always the dominant types of land use and transformation.Therefore,reasonable use and protection of the forest land,grassland and cultivated land resources are the necessary ways to construct the ecological environment in Zhuozi County.
