芜湖市城市用地结构演变特征研究

A Research into Characteristics of Urban Land-Use Structure Evolution of Wuhu City

基于信息熵、均衡度等数学模型的基本原理,对安徽沿江开放城市——芜湖近10年的城市用地结构演变特征进行了研究,结果表明:早期工业用地比例过高,城市用地结构不合理;后期工业用地比例下降,城市绿地大幅度增加,城市职能与用地结构趋向吻合。该研究为今后城市土地的可持续利用与发展提供了参考价值。

On the principles of Shannon Entropy and equilibrium, this paper studies the urban land use structure evolution of Wuhu City,with the conclusion that greater proportion of initial industrial land-use resulted in an irrational structure of the land use of the city and that land-use structure of the later period of the city was regulated, conforming to the functions of cities.The research offers valuable reference for the sustainable utilization of urban land and the development of cities.
