- Abstract:
- Urbanization means urban expansion and the diffusion process of urban culture,urban lifestyles and values in the rural areas.Farmland conversion is an inevitable phenomenon,changes in land resources reflect certain social and economic development processes.This paper analyzes the variation characters of cultivated land in the context of urbanization;then with the basic cultivated land,socio-economic demographic data in 1990-2008 of Hexi corridor,using principal component analysis and gray relational analysis method,the human driving force on changes of cultivated land was verified and analyzed.The results show:(1) In last 20 years,changes of cultivated land in the Hexi Corridor had experienced a wavelike process of change as ’increase-drastically reduced-dramatically increasing-slowly decreasing-smoothly increasing’;(2) Economic growth and farmland conversion existed an approximate ’kuznets’ curve type relationship;(3) Human driving forces made significant effect on cultivated land change of urban areas which are represented by urbanization level,social economy and agricultural technology.
