Study on Performance Evaluation of Intensive Land Use in Wuhan City:1998-2010
Based on the relevant data from 1998 to 2010 in Wuhan city,this paper evaluates the performance of intensive land use in Wuhan and 13 regions under its jurisdiction. The result shows that intensive land use has promoted the improvement of land yield and the development of economy in Wuhan,and also saved the quantity of lands to some extent. However,there are some differences among each region in the intensive land use performance. In the three stages,the intensive land use for land yield contribution of the main urban areas is significantly higher than that in the suburbs,while the increase of the main city areas slows down gradually and the growth rate in the suburbs is obviously increasing. As for the contribution to gross economic volume,the suburbs overtake the main urban areas in the third stage. In terms of land saving amount,the total land saving quantity is basically equal in each stage. But the land saving quantity of urban areas descends persistently,while the suburbs rise steadily at the same time. Rural-urban fringe zones such as Hongshan district and underdeveloped main city areas such as Hanyang district show that land saving quantity first increases and then decreases.
