| 1 | Urban Agglomeration Formation and Its Spatiotemporal Expansion Process in China: From the Perspective of Industrial Evolution显示文摘Urban agglomeration research has received increasing attention in China’s national development strategies, and has become a hot topic in academic research. This study develops a theoretical framework that explores the formation mechanism and expansion process of urban agglomerations from the perspective of industrial evolution, and identifies the development issues and their causes by taking Yangtze Delta and Beijing-Tianjin-Hebei urban agglomerations as case studies. In the process of urban agglomeration formation within a free market, as has happened in Yangtze Delta region, the central city develops first, its secondary industry is then transferred to its neighboring cities, and the work division and cooperation with the neighboring cities is gradually established. However, in the 1990 s, aiming to become an international metropolis, Beijing implemented a series of administrative policies to encourage the reduction of the secondary industry and the development of the tertiary industry, before its secondary industry were fully developed and transferred to its neighboring cities. This delayed the integration process and the development of the Beijing-Tianjin-Hebei urban agglomeration. This study builds a good foundation for the construction of the theoretical system’s urban agglomeration study, and provides references for decision making in an urban agglomeration development. | NIU Fangqu YANG Xinyu WANG Fang | 2020 | Chinese Geographical Science2020，30，3： | 2 |
| 2 | A study on urban economic vulnerability evaluation system显示文摘中国城市面对高、很快增加的暴露到灾难。减少灾难危险是为灾难管理和风险减小的一项直接、有效的反措施,它要求对社会和经济的危险的首先客观的评价。对经济危险的评价是在风险评估,为有效灾难预防计划的一个前提和为紧急情况管理的一个重要的底的重要的步。这份报纸为估计经济危险开发一个模型,它各种各样的工业部门和经济密度的企业,危险和重要性的尺寸考虑。基于模型,这份报纸开发一个城市的经济危险评估系统并且在北京把它用于 Haidian 区域,结果帮助鉴别在它的 647 ,块在哪儿高度并且很高度以经济脆弱,并且它为灾难前预防计划提供有用、实际的信息,灾难有准备和紧急情况管理。在这研究开发的经济危险评价模型和系统使让政府快速评估一般经济危险并且识别特定的脆弱的区域可能,做对灾难管理信息系统和决定支持系统的贡献。 | YUAN Haihong NIU Fangqu GAO Xiaolu | 2015 | Journal of Geographical Sciences2015，25，10： | 2 |

| 4 | Urban Metabolism Based on Emergy and Slack Based Model: A Case Study of Beijing, China显示文摘The key to studying urban sustainable development depends on quantifying stores, efficiencies of urban metabolisms and capturing urban metabolisms′ mechanisms. This paper builds up the metabolic emergy account and quantifies some important concepts of emergy stores. Emphasis is placed on the urban metabolic model based on the slack based model(SBM) method to measure urban metabolic efficiencies. Urban metabolic mechanisms are discussed by using the regression method. By integrating these models, this paper analyzes the urban metabolic development in Beijing from 2001 to 2010. We conclude that the metabolic emergy stores of Beijing increased significantly from 2001 to 2010, with the emergy imported accounting for most of the increase. The metabolic efficiencies in Beijing have improved since the 2008 Olympic Games. The population, economic growth, industrial structures, and environmental governance positively affect the overall urban metabolism, while the land expansion, urbanization and environmentally technical levels hinder the improving of urban metabolic efficiencies. The SBM metabolic method and the regression model based on the emergy analysis provide insights into the urban metabolic efficiencies and the mechanism. They can promote to integrate such concepts into their sustainability analyses and policy decisions. | SONG Tao CAI Jianming XU Hui DENG Yu NIU Fangqu YANG Zhenshan DU Shanshan | 2015 | Chinese Geographical Science2015，25，1： | 1 |
| 5 | Review of and prospects for China's human and economic geography显示文摘The 'High-Level Forum of the Development of China's Human Geography Under the Background of Change' was held in Beijing on January 22-23, 2016. More than 30 professors attended this forum. At this conference, they discussed the major progress made towards developing China's human geography, as well as the existing problems, limiting factors, opportunities, international collaborations, emerging directions, and prospects in the development of this discipline. In recent years human geography has boomed, generating many important opportunities for its development. Establishing an academic community for joint research on major research issues and collaborative innovation is a promising and important route to take. We should embrace both domestic and international characteristics, to promote China's human geography onto the world stage. Meanwhile, the cultivation of various scholarly talents is also of great value to enrich and advance the discipline. | CHEN Mingxing LONG Hualou WANG Chengjin HUANG Jinchuan NIU Fangqu | 2017 | Journal of Geographical Sciences2017，27，12： | 1 |

| 7 | Novel approaches to the multiscalar display of vector data显示文摘There are many challenges to achieving quality multiscalar displays of vector data in geographical information system(GIS).Acknowledging and making use of the differences between traditional cartographic generalization and multiscalar display in GIS,this paper focuses on novel approaches to the definition of small objects and the establishment of scale sequence.The ease of implementation and efficacy of the solutions proposed are exemplified and analyzed.Possibilities for further research into the multiscalar display of vector data in GIS are thereby suggested. | NIU Fangqu CHENG Changxiu | 2012 | Geo-Spatial Information Science2012，15，4： | 0 |
