Land Use Change And Simulation Studies

The study of land use change in the current socio-economic research front and hot science research topics. With the rapid development of socio-economic, Qianjiang City, the land to support an important carrier of the region’s rapid economic growth and departments, and development of various industries based on the shortage of land resources has become increasingly prominent, and land resources supply and demand more further increase the trend. The study of Qianjiang City land use dynamic changes, sustainable development, utilization, protection and management of its limited land resources has important theoretical and practical significance of Qianjiang City to coordinate the development of social, economic, environmental harmony.Using remote sensing data of the three different stages in the year2000, Supermap and other technical analysis software, respectively obtained Qianjiang City in2000,2005and2010land use data and graphics, in the establishment of study on the basis of the starting year2010, Evaluation2010Qianjiang City land use status and to analyze regional land use transfer the changes obtained two transition probability from2000-2005and2005-2010, respectively matrix, and then analyzes the Qianjiang City in2010and2000during the land use structure change, and reveals the region’s land-use dynamic characteristics, and use Markov chain of land use change forecasting model to predict2020Qianjiang City land use structure the trend, combined with the final analysis of the results, the paper presents the Qianjiang City, sustainable land use policies and measures. So as to draw the following conclusions:Analysis showed that (1) From the land use status of Qianjiang City in2010, in the city’s domain the largest proportion of land area is arable land, waters and water conservancy facilities;(2) the main trend line by the Qianjiang City, the total change of land types land area of cultivated land, and water, and water conservancy facilities, a significant reduction in the town village and industrial land, forest land and transportation land area increased significantly;(3) we can see from the flow of conversion of land types in the region, Qianjiang City, around the class between the nearly all each other circulation changes;(4) through the forecast, Qianjiang City in2020, agricultural land (cultivated land, grassland), changes in the characteristics of other lands and waters and water conservancy facilities or tend to reduce, but tend to slow down reduction a lot; town village and industrial land, forest land and transportation land area is still performed in order to increase tends to increase the rate of change has slowed. This is the Qianjiang City, land use changes in structure and layout of a more rational and consistent with sustainable development strategy;(5) The paper concludes with the Qianjiang City, take the sustainable use of the development of countermeasures and suggestions for future land.
