Study On Land Use Change And Its Driving Forces Of Datong

Research on land use change is the frontier and the hot spots in the global change research, and research on regional land use change and its driving forces is one of the most important parts. In the study area of Datong, with the Remote Sensing and Geographic Information System technological support, the spatial character of land use change are analyzed between 1996 and 2002; and the soci-economic driving forces are also analyzed by social science software SPSS 12.0 combining social-economic statistics of study area. The results show that:(1) Great changes of land use have been taken from 1996 to 2002. Land use change degree has a little increase and land use shows regional difference. The change of cultivated land, orchard/woodland, construction land and unused land is outstanding in land use change speed and extent. Cultivated land and unused land decreased while construction land, communication land and orchard/woodland increased in the quantitative. On the spatial distribution, the change of land use extent indicate that it is bigger in mountain region than in basin region and hilly region, land use indexes change of Cultivated land, orchard/woodland and unused land are main in the area where altitude is more higher while the change of construction land is acute around the country city.(2) The results of Canonical correlation analysis between land use change and its sod-economical driving forces show that the increasing of Total Population is the main driving force of construction land increase, the increasing of Total Rural Economical Income is the main driving force of orchard/woodland change, and the increasing of Larger Animals at Year-end and Percent Pure Income is the main driving force of cultivated land...
