Abstract:

Measurements of urban land transition with multiple perspectives and multi-time are essential to identifying inherent driving forces of urban land transition, urban land transition control and neo-urbanization construction in China. Here,based on the definition of urban land transition a characterization framework was built. The characteristics of urban land transition,including amplitude,speed and equilibrium were analyzed using transition degree,transition dynamic degree,Lorentz curve and coefficient of variation in the Middle Yangtze River Economic Belt from 1990 to 2015. We found that the internal structure of urban land sources has changed markedly. The proportion of cultivated land in new urban land continuously decreased,while the proportion of forest and other construction land gradually increased. An indirect way that cultivated land is converted to urban land was found whereby cultivated land is firstly converted to other land then to urban land. From 1990 to 2015 a rapid and unbalanced transition process occurred in the Middle Yangtze River Economic Belt:urban land area increased 153.34%,the transition degree was 0.62,and the Gini coefficient of the new urban land area was 0.53. At the same time,the trend in increment,degree and dynamic degree of urban land transition underwent decrease-increase-decrease. A two horizontal lines and three vertical lines region with high transition degree was highlighted and formed by counties along main roads and railways. The distribution pattern of counties with high transition dynamic degree appeared as a H shape,with counties mainly located in marginal areas of the Belt. The transition degree decreased with an increase in elevation,the dynamic degree was increased at first and then decreased. Compared to non-metropolitan areas,the transition degree for metropolitan areas was higher,but the dynamic degree was lower.

Key words: urban land, transition, equilibrium degree, Spatiotemporal dynamic patterns, Middle Yangtze River Economic Belt
