Analysis of Land Use Change and Its Driving Mechanism in Coastal Region——A Case Study of Dalian City

The change of land use type and its driving mechanism have been a hot topic in the existing studies of land science.Based on the data collected through documentary research and field observation,land use change in Dalian city has displayed an important feature between 1996 and 2005,that is the decline of cultivated land and unused land,the increase of constructed land.Then the driving forces of land use change in Dalian City was analyzed.On the basis of the study,the driving mechanism of land use change in coastal cities was proposed,which is the outer driving mechanism(spacial-temporal effects driving) and the inner driving mechanism(nature-human driving),and their relationship between each other.It is necessary to use the thought of system when the driving force and driving mechanism of land use change is studied,so that the macro and meso analysis could combine with micro analysis in some area and achieve the combination of qualitative and quantitative research methods.
