The discourse regarding place attachment (PA) has grown even more divergent, and an array of scholars and practitioners apply place attachment concepts in their work, drawing out associations between PA and environment-related behavior and revealing how an understanding of people’s attachment to place can influence research, policy, and design practice. In this paper, we use bibliometrics and CiteSpace software to quantify and visualize 528 publications of place attachment and environment-related behavior research (PAEBR) in the core collection database of Web of Science (WoS) from 1 January 2004 to 1 November 2022 and trace the main overview of the research from the number of published papers. First, we present the number of papers published, research discipline distribution, the core authors of articles, the fundamental condition of countries and research organizations, and the major journals of articles involved in PAEBR through bibliometrics. Second, we identify trending research topics in PAEBR using keyword co-occurrence analysis. The results show that the four research trending topics involved climate change, pro-environmental behavior, and environmental threat. All of these provide readers with a preliminary understanding of PAEBR, indicating that cooperation and analysis involving multiple disciplines, specialties, and perspectives will become the dominant trend in this field.

The relationships between spatial production, urbanization and sustainable development are becoming a focus of the international academic cycle. Urbanization dominated by spatial production driven by capital and power often produces and enlarges uneven development, which leads to multiple eco-environmental problems. Thus, the key to development lies in whether the pattern of urbanization is in harmony with the ecological environment. However, previous researches mainly concentrate on spatial production in developed countries or regions. The urbanization and sustainable development of less-developed regions, with complex and fragile ecological environments, are often overlooked. It is a new idea to explain the relationships and interactions between spatial production, urbanization and sustainable development based on less-developed regions by the theory of spatial production. The paper chooses the Hexi Corridor as a typical case, puts forward a conceptual framework and explores the process of spatial production from 2000 to 2017. The results reveal that urbanization in the Hexi Corridor is a multidimensional socio-spatial process: power and capital gave birth to a higher urbanization and accelerated the process of urbanization, however, the urban-rural gap between regions has not narrowed accordingly. Driven by comprehensive interests, local governments often take some extreme measures to forcefully promote the urbanization process, thereby violating the goals and requirements of sustainable development. At present, there is an urgent need to coordinate the relationship between urban and rural regions on different scales and transform the urbanization model from traditional spatial production to a new-type of urbanization with people-oriented and sustainable development.

【目的】城市网络结构韧性是城市空间组织恢复力与稳定性的重要保障，当前研究多采用单一要素流且聚焦发达地区，而结合多维要素流同时关注欠发达地区网络结构韧性的成果相对较少，因此，本文以欠发达的西北地区为研究对象，并基于多维要素流探究其网络结构韧性，以期弥补相关研究在地域上的留白，并丰富多维要素流视角下网络韧性的实证分析。【方法】以西北地区51个地级行政单元为研究对象，从经济、交通、信息3个视角入手探究2022年西北城市网络的结构特征，定量测度其层级性、匹配性、传输性和集聚性，进而利用计算机仿真模拟研究中断场景下西北城市网络结构韧性，据此提出优化策略。【结果】①西北51个地级行政单元的经济、交通、信息网络总体呈“东密西疏”的分布格局，网络具有“核心-边缘”特点，但3类网络结构存在明显差异。经济网络密度较小、核心节点间的粘性较大，呈现出“以强带弱”与“强强联合”共存的特征、“多组团”格局和“片态化”发展态势；交通网络联系较为紧密，城际联系惯性较强，呈现出“小世界”效应、“纺锤型”格局和“紊态化”发展态势；信息网络具有广覆盖性和强渗透性，呈现出协调性特征、“条带状”格局和“湍态化”发展态势。②3类网络的层级性和匹配性差异较大，传输性和集聚性差异较小。经济网络“马太效应”明显，呈现出核心强同配性和边缘弱异配性特征；交通网络趋于立体化发展，表现出小范围“健壮性”和大面积“脆弱性”；信息网络具有高异配韧性，表现出网络结构扁平化和联系路径多元化特征。③蓄意攻击对网络韧性的破坏力显著高于随机攻击，对比脆弱节点，核心节点遭受打击对网络运转效率具有更大影响。【结论】区域发展不均衡的问题在欠发达地区尤为明显，核心城市“权力”集中但辐射半径较短，位于边缘的城市发展动力不足。3类网络之间的韧性特征同中存异，不同攻击模式下网络韧性具有阶段性变化特征。为促进区域可持续发展，应针对区域特性制定应对政策。

As one of the core systems of a city, urban rail transit plays a pivotal role in ensuring the safe, rational, and efficient operation of the city. Therefore, it is of great significance to ensure the safe operation of urban rail transit network to improve the operation efficiency and economic level of the city. The prerequisite to ensure the safety of urban rail transit network is whether the risk situation of urban rail transit network can be reasonably and accurately evaluated. In order to evaluate the risk level of urban rail transit network reasonably and accurately, firstly, with full consideration of the characteristics of urban rail transit, the risk evaluation system of urban rail transit network was established in this paper based on the three levels of regional economy, social resources, and rail transit. Secondly, based on the entropy-TOPSIS-coupling coordination model, the single-factor influence and multifactor coupling influence in the index system are calculated and analyzed, respectively; thus the coupling coordination degree of urban rail transit system is obtained, so as to quantitatively evaluate and analyze the risk situation in urban rail transit network. Finally, based on the actual data of Shanghai from 2000 to 2016, the case simulation and analysis are carried out. The results show that the two indicators of regional economy and social resources are more likely to affect the safety state of urban rail transit. At the same time, the safety factor of urban rail transit coupling system is increasing year by year and gradually develops from disorder to order. This is more in line with current urban rail transit condition, demonstrating the rationality and accuracy of the entropy-TOPSIS-coupling coordination model proposed in this study.

The urban heat island effect is becoming more and more serious due to the continuous expansion of cities in China, and improving the urban thermal environment is an important prerequisite for creating a livable city. Based on the Landsat TM images of 2001 and 2011 and Landsat TIRS images of 2021, this study investigated the spatial and temporal distribution and evolution characteristics of the urban thermal environment in Lanzhou City in the last 20 years by using the radiation equation conduction method to invert the surface temperature of Lanzhou City. The results show the following: (1) The radiation range of the medium temperature zone in Lanzhou City spreads in an “extended” style from 2001 to 2021 until it covers the whole main urban area, the secondary high and low temperatures decrease, and the corresponding medium temperature zone increases over a large area. (2) The average temperatures of Lanzhou urban area and its arable land, forest, grassland, and water area within the urban area reaches 10–25 °C, and the heat island area decreases by 9.56% in 20 years, with the high-temperature zone decreasing by 42.32%. (3) The proportion of water bodies and the proportion of impermeable surfaces are dominant factors in the spatial differentiation of surface temperature, and the interaction and synergy of various influencing factors affect the spatial differentiation of surface temperature.
