摘要
中国已经进入城市化发展的加速阶段,快速的城市化过程加大了对土地的高需求,土地集约利用直接影响到武汉城市圈土地利用和管理效果,关系到城市圈的城镇化进程。采用全排列多边形综合图示指标法对武汉城市圈2001—2010年间土地集约利用变化进行了量化评价。研究表明:(1)全排列多边形图示指标法可用于土地集约利用的评价,该方法系统整合了评价对象的多种因素,并减少了主观因素的影响,使评价更为客观科学;(2)单项指标显示,10a间,武汉城市圈土地投入强度、土地利用强度、土地产出效益和土地环境质量均有明显提高;(3)武汉城市圈土地集约利用综合指数总体呈增长态势,且前阶段的增长速度慢于后阶段,经济增长方式发生改变。因此,武汉城市圈在未来一段时间应把握住发展契机,通过增强土地利用的投资强度和产出绩效,不断提高土地集约利用水平;同时注重土地环境质量改善,优化城乡建设用地结构,提高土地的集约利用水平。
Nowadays, China has moved into the fast urbanization period. There is a high demand for land in the rapid urbanization process, and intensive land use has a great impact on land use and management of ag- glomeration. In this paper, entire-array-polygon evaluation model has been employed to quantitatively ana- lyze the changes of land intensity in Wuhan metropolitan agglomeration from 2001 to 2010. The result shows that： （1） the entire-array-polygon evaluation model can be used for evaluating the land use intensity, and it also has an advantage that it can take into account the systematic feature of the evaluated object and reduce the subjective effect; （2） in terms of the single indicator analysis, it indicates that economic growth is not only the main driving forces for construction land expansion, but also the key impact factor of intensive land use level improvement; （3） the comprehensive land use intensity of Wuhan metropolitan agglomeration was gradually increasing during the research period. However, the trend can further divided into two stages, i. e. , the former stage increased slower than the latter. So, Wuhan metropolitan agglomeration should seize the chance to develop in the future by increasing the land use investment and output efficiency so as to enhance land intensive use level. Meanwhile, it should lay more emphasis on better land environmental quality, optimize land use structure and increase land use intensity.
