吉林市城市土地利用效率及其有序性分析

本文基于吉林市2008年社会经济统计数据及建成区城镇地籍更新数据,以吉林市城市土地利用作为研究对象,采用DEA方法,用Matlab软件进行数据处理,对吉林市城市土地利用效益进行定量分析和评价,同时运用信息熵对吉林市建成区的土地利用有序性进行了分析。研究结果表明:吉林市城市土地利用效率整体较高,船营区、丰满区和昌邑区的利用效率达到最优,龙潭区因存在土地产出不足,土地利用效率相对较低;吉林市土地利用结构有序性整体较低,昌邑区因建设用地比重大,有序性在各区中最低。建议严格执行土地利用总体规划和用途管制制度,强化土地利用总体规划与城市规划的实施,使土地利用结构向有序性转化,积极实施退二进三的政策,保证各用地类型数量的均衡协调。

JILIN URBAN LAND USE EFFICIENCY AND ITS ORDERLINESS

This paper, based on Jilin 2008 statistical data in economy, society and urban construction, based on case study on Jilin urban land, applies DEA method and Matlab software to evaluate quantitatively the urban land use profits, and uses information entropy to analyze the orderliness in Jiancheng district land use. The results indicate a relatively high in land use efficiency in Jilin city, optimal in Chuanying district, Fengman district and Changyi district, relatively low in Longtan district due to its deficiency in land output, and generally low in structural orderliness, lowest in Changyi district due to its big construction land quantity. This paper suggests to strictly implement the gross land use planning and control, to enhance the execution of the gross land use planning and urban planning, to concert land use structure in orderliness, and to actively carry out “seceded-2-acceded-3” policy to ensure a balance among all kinds of land quantity.
