ANALYSIS OF SPATIAL STRUCTURE OF URBAN LAND FOR CONSTRUCTION IN EASTERN COASTAL OF ZHEJIANG PROVINCE

Based on the urban land-use data about Ningbo,Taizhou and Wenzhou in China Urban Construction Statistics Yearbook(2008),we introduced the concept of Location entropy,Lorenz curve and Gini coefficient to analyze the difference of the spatial distribution of urban land for construction in eastern coastal of Zhejiang province qualitatively as well as quantitatively.The results indicated that,on the one hand,the regional advantages of distribution of the urban construction land for residence tended to be in all county-level cities in eastern coastal of Zhejiang province;the urban land for industry,warehouse and transport tended to be near the core urban area of Ningbo,Taizhou and Wenzhou;in addition,Taizhou's urban land for public facilities and also utilities held an advantage;and the core urban area of Wenzhou's land for street and square,greenbelt and special use shown by the regional advantages were very obvious.On the other hand,the spatial distribution of urban land for construction in degree in eastern coastal of Zhejiang province showed that,the most unbalanced land type was for special use(which Gini coefficient was above 4.0-the international alert line);but the distribution of the land for greenbelt and utilities were relative reasonable;the warehouse land was rather evenly distributed;and land for residence,public facilities,industry,transport,street and square were more evenly distributed.It is concluded that the regional advantages of distribution of the urban construction land and its spatial distribution characteristics reflect the economic,social,demographic and other dimensions of economic performance well.The result can be helpful for the structural optimization of urban land use in coastal area.
