Study on Characteristics and Driving Forces of Construction Land Changes in Gansu Province

WANG Hai-hong,CHANG Yan-ni,DU Jing-shen,Qi Fei(School of Management,Lanzhou University,Lanzhou 730000 Gansu,China)  
According to statistical and datailed survey date of constructive land use from 1997 to 2004,the special-temporal changes of constructive land-use structure in Gansu Province during the last 8 years were analyzed.Based on which the driving forces of information entropy were discussed in this article.The results showed: the information entropy of the constructive land use structure in Gansu has been rising in general since 1997,in other words,the multiple of constructive land has been rising,land use structure tends to equilibrium.The driving forces were analyed,and the following conclusions were reached: population growth and urbanization are the most closely related to the information entropy of constructive land use structure,then followed by other economic factors.
