【摘要】：人多地少、土地资源稀缺是我国的基本国情,采用建设占地少、利用效率高的用地方式是国家长期坚持的一项根本方针,集约用地评价对于集约用地具备重要指导作用。本文以长江经济带主要地级市2000~2014年间相关建设用地数据、社会经济数据为基础,从建设用地投入水平、利用程度、产出水平和可持续性4个方面构建建设用地利用评价体系。用主成分分析法,对2001~2005年、2006~2010年和2011~2014年三个时段的建设用地集约水平进行评价并赋分,利用Arcgis软件空间化显示,结果表明:(1)在时间上,长江经济带的城市土地集约利用水平整体呈现上升趋势;(2)空间上,经济带东部城市建设用地集约节约水平总体高于西部;(3)城市建设用地集约水平与经济发展水平呈现明显相关性。对建设用地集约水平评价分析将有助于了解城市土地集约利用空间分异和变化趋势,为未来城市土地优化利用和可持续发展提供依据。
[Abstract]:The basic condition of our country is to have fewer people and less land and scarce land resources. It is a fundamental policy for the country to adopt the method of land use with less construction and high efficiency. The evaluation of intensive land use plays an important role in guiding the intensive land use.Based on the relevant construction land data and social economic data of major cities in the Yangtze River economic belt from 2000 to 2014, this paper constructs an evaluation system of construction land use from four aspects: input level, utilization degree, output level and sustainability of construction land.Using principal component analysis method, the paper evaluates and marks the intensive level of construction land in three periods from 2006 to 2010 and from 2011 to 2014. The results show that: 1) in time by using Arcgis software spatial display.The level of intensive urban land use in the Yangtze River economic belt is on the rise as a whole.The intensive saving level of urban construction land in the eastern part of the economic belt is generally higher than that in the west of China (3) the intensive level of urban construction land has obvious correlation with the level of economic development.The evaluation and analysis of the intensive level of construction land will be helpful to understand the spatial differentiation and change trend of urban intensive land use and provide the basis for the future urban land use optimization and sustainable development.
