摘要
城市土地利用潜力水平与城市现实的集约水平密切相关,并且直接关系到城市未来的综合发展.分别从社会、经济、环境三个层面选取12个指标建立城市土地利用潜力评价体系,以中国20个城市为地域研究单元,对其进行全面测度和比较;运用主成分分析法,分析因子的贡献率和各因子载荷量,并进一步利用主成分分析的分类功能,根据所提取的主成分因子对评价单元进行潜力水平分类.结果表明,中国城市的土地利用潜力分为3个大类,6个细类,其中,北京、重庆归类为土地潜力利用水平较好;沈阳、武汉、太原、西安、昆明、天津、南京、哈尔滨、长春、大连、郑州、成都、济南、石家庄归类为土地利用潜力水平一般;青岛、杭州、广州、上海归类为土地利用潜力水平较差.
Urban land use potential level which is closely related to the intensive level is directly relevant with the comprehensive development of China cities, This paper develops an assessment system of the urban land use potentials （ASULUP） which includes 12 indicators settled in three layers： social, economical and environmental perspectives. The indexes of the ASULUP, including 20 cities in China mainland, are evaluated and compared thoroughly by developing the assessment system. The principal component analysis （PCA） is applied to rotate them by the method of varimax. Analyzing the component matrix, the principal components are extracted and named according to the comprehensive meaning of indexes. Moreover, utilizing the classification function of PCA method, the appraisement units are classified and ordered. The study shows that the ASULUP of the cities display with three kinds of levels. Beijing and Chongqing are divided into the better potential level; Shenyang, Wuhan, Taiyuan, Xi＇an, Kunming, Tianjin, Nanjing, Haerbin, Changchun, Dalian, Zhengzhou, Chengdu, Jinan and Shijiazhuang are categorized into the common potential level; Qingdao. Hangzhou, Guangzhou and Shanghai are subscribed to the less potential level of China.
