The Study On Land Use Change And Driving Factors At Country Scale

The research of land use change is the important foundation for the ecological change research, which is also the policy-making basis for regulating the human behavior. Based on the widely review of related research on land utilization change and its human driving forces at home and abroad ,this paper takes the sifting data and the correlation data, the statistical data of minqing land utilization as the research foundation, and takes the land resource sustainable use theory as the instruction. The research unifies the specific geographical environment and social conditions in minqing, uses the method which unifies the quota and the qualitative analysis, has analyzed the temporal and the spatial variation situation about land utilization in minqing from 1996 to 2005. By selecting suitable humanity driving influence factor, discusses human driving factors that cause the land utilization change in minqing and promulgates the minqing land utilization change rules.According to the analysis, this paper draws the following conclusions:Land utilization variation rate in minqing is quick and the annual variation rate has achieved 0 .12%; The land mass variation is remarkable also exists obvious region diference; From 1996 to 2005 years, minqing's land use degree rate is -0.001,which shows that this country's land use was being in adjusting period for this 10 years, land use degree quantity is developing to be recessionary, but utilize degree rate is not too great.A qualitative analysis shows minqing land use change is mainly afected by population growth, economic factors, urbanization, industrialization, the political and technology development factors conjunctly;Quantitative analysis shows that economic development and the improvement of pepole's consuming level is the most influential factors which affect the land use change.At the same time, taking the land utilization change and the driving factors research as the foundation and unifying the minqing actual situation, some constructive suggestion about minqing land utilization is given in the end.
