| 摘 要： | 目的]对天山北坡经济带12个主要城市的土地集约利用水平进行评价。方法]从土地利用的经济性、社会性及生态性3个内涵出发,构建基于过程的"压力—状态—响应"(PSR)评价指标体系,采用主成分分析法对评价指标进行赋权,按百分制分别测算土地集约利用水平和PSR系统协调度。结果]天山北坡经济带城市土地集约利用水平差异的主要影响因素一方面在于各城市的经济发展水平,另一方面在于人口密度、土地利用结构、经济增长等对土地集约利用产生压力的因素。将PSR协调度与土地集约利用水平进行相关分析,其Pearson相关系数达到0.886,二者显著相关,说明在总体上PSR系统协调度越高,城市土地集约利用的水平也越高。结论]为提高城市土地集约利用水平,在规划开发中一方面要结合城市土地集约利用的内涵,另一方面也要从各城市所处的发展阶段及发展目标出发,通过合理的产业转型,优化土地利用结构等方式,制定有效的引导措施来提高土地利用的综合效率。

| Abstract: | Objective] To evaluate urban intensive land use of 12 cities in the economic belt on the north slope of Tianshan Mountains.Methods] With the consideration of economic, social and ecological effects of land use, we established the pressure-state-response (PSR) procedure model as an evaluation system. By applying the principal component analysis method, the urban intensive land use level and the PSR coordination level were calculated according to percentile.Results] The main factors that affect the spatial variations of urban intensive land use in the study area is related to the urban economic development level, the pressure on urban intensive land use, such as population density, land use structure and economic growth, etc. According to the correlation analysis, there was a positive correlation between the PSR coordination level and the urban intensive land use level, and the Pearson correlation coefficient was 0.886.Conclusion] To improve the level of urban intensive land use, planning and development should both be combined with the connotation of urban intensive land use according to the development goal and stage. Reasonable industrial transformation, optimal land use structure can be taken as effective ways to improve the comprehensive efficiency of the land use. |
