| 1 | 1990-2010年长三角城市群城市扩展时空规律分析显示文摘随着城市化过程的深入,城市群建设已成为中国推进新型城镇化战略的重要举措之一,长三角城市群作为我国发育程度最高的城市群,研究其城市扩展的时空规律对于政策制定、合理规划具有重要参考作用.本文利用长三角城市群1990—2010年间5个时期的城镇建设用地监测数据,选取首位度指数、年均扩展量、土地利用效率等指标,对比分析不同城市扩展随时间变化的过程特征.结果表明:20年来该城市群内城镇建设用地面积增加量超过8 000km2,各时段中2005—2010年扩展最为剧烈;城镇建设用地首位度指数逐步降低,该城市群建设用地规模呈现多中心化的趋势且正在强化;各城市城镇建设用地年均扩展量及土地利用效率随时间的变化轨迹呈现出明显的省内相似性和省际异质性;绝大部分城市城镇建设用地利用效率呈现出先升高后降低的趋势,1995年以来各城市城镇建设用地利用效率普遍显著降低,说明粗犷低效蔓延仍是该地区城市用地扩展的主要模式. | 高啸峰 刘慧平 张洋华 吕颖 刘湘平 | 2016 | 北京师范大学学报(自然科学版)2016，52，5： | 13 |
| 2 | 长江中游城市群综合交通运输体系优化研究显示文摘《长江中游城市群发展规划》(2015)提出,要将长江中游城市群打造成为全国经济增长第四极。'经济发展,交通先行',综合交通运输体系优化是带动长江中游城市群发展的关键因素和重要保障。文章在深入研究长江中游城市群综合交通运输网络布局现状和问题的基础上,借鉴英国伦敦城市群、美国东北部大西洋沿岸城市群以及日本太平洋沿岸城市群等世界级城市群在交通运输规划、管制、枢纽衔接和政府合作等方面的经验,提出了加快制定长江中游城市群综合交通运输体系规划、提高城市群综合交通运输网络运行效率与衔接度、推动'互联网+综合交通运输体系、提高综合交通运输供需平衡度'模式的创新发展等对策建议,为长江中游城市群综合交通运输体系优化乃至全国综合交通运输体系优化提供了理论依据和经验借鉴。 | 周正祥 毕继芳 | 2019 | 中国软科学2019，0，8： | 12 |
| 3 | Extraction of Basic Trends of Urban Expansion in China over Past 40 Years from Satellite Images显示文摘If urban sprawl is to be avoided in China in the next ten years, it is not only crucial to understand the overall history, current status, and future trends of urban expansion there, but also these differences, and this is presently lacking. In this study, remotely sensed images with approximately 30 m spatial resolution were used to quantitatively assess the spatial and temporal patterns of urban expansion of 60 Chinese cities(1973–2013). Urban-expansion-process curves of the cities studied were drawn using annual expansion area as an indicator. Curve similarity analysis generated four basic process modes of urban expansion in China. These included cities that: 1) peaked around 2004 and then decelerated; 2) peaked around 2010 and then decelerated; 3) showed sustained acceleration, and 4) showed continued deceleration. Four basic process modes represented cities under different levels of development stage. Geographic location was found to be the most related characteristic to urban expansion process. Regional development policies at the national level in each region also showed highly temporal consistency with fluctuation characteristics of urban expansion process. Urban characteristic such as population size and administrative level were not found to be significantly related to urban expansion-process modes. Understanding the basic process-mode categories well is extremely important for future regional-balance planning and development of macroeconomic policies. | WEN Qingke ZHANG Zengxiang SHI Lifeng ZHAO Xiaoli LIU Fang XU Jinyong YI Ling LIU Bin WANG Xiao ZUO Lijun HU Shunguang LI Na LI Minmin | 2016 | Chinese Geographical Science2016，26，2： | 4 |
