Abstract:

According to the landuse statistics and the socioeconomic data from 1999 to 2007,the dynamic evolution of Liangping County’s landuse structure was exemplified based on the information entropy principle and Markov transfer matrix model.The results show that the information entropy 〖WTBX〗H〖WTBZ〗 of Liangping County’s landuse structure has gone through three stages,that is,1999～2002 continual rising stage and 2002～2003 sharply decreasing stage and 2003～2007 fluctuating stage.Meanwhile,the disorderly development tendency of the landuse structure is not obvious;the change in the degree of balance and dominance is similar to information entropy.The types of land have been mainly transferred from cultivated land to woodland,land for traffic,land for residential settlements and industry mining.The political and economic policies,which have an effect on the evolution of landuse structure in Liangping County,have been analyzed qualitatively.The main driving factor to economic society has been discussed by means of the principal component analytical method.Through the above analysis,it would be concluded that the main driving forces affecting the dynamic evolution of the county’s landuse structure are political and economic policies and economic development.Finally,a future development orientation for Liangping County has been made,referring to the analytical results,that is,distinctive agricultural county,focusing on the development of agriculture and forestry products processing as well as cultural ecotourism.
