| 1 | 兰西城市群土地利用/覆被变化模式特征——基于强度分析框架显示文摘【目的】基于土地利用转移矩阵提出土地利用/覆被变化(LUCC)强度分析框架,从绝对和相对强度两个角度分析地类之间的转换趋势及其对土地利用/覆被结构的影响。【方法】构建土地利用/覆被变化强度图谱以直观展现区域LUCC关键模式,并以兰西城市群为例进行实证研究。【结果】土地利用/覆被变化强度图谱融合绝对和相对强度信息,既可反映如耕地倾向于转化为建设用地、水域向林地转化的强度较低等LUCC的区域共性规律;也能较好地揭示兰西城市群作为西部生态脆弱区中城市化重点区的特异性变化模式,如2010—2020年期间,兰西城市群在未利用地向水域、草地向耕地及建设用地向未利用地的转化过程中均表现出倾向性的变化模式,但受气候变化、占补平衡政策及土地整治项目管护不周等因素影响,分别表现为系统倾向性、绝对倾向性及相对倾向性的变化特征。进一步与转移矩阵及桑基图对比解析可知,绝对强度和相对强度间不存在直接关联性,所构建的强度分析框架及图谱受地类比例和区域整体LUCC强度的影响相对较小。【结论】本文提出的强度分析框架具有可行性,可为识别及解析区域LUCC关键模式及规律,优化土地资源管理政策提供科学支撑。 | 李帅呈 龚健 杨建新 陈光 张重 张木茜 | 2023 | 资源科学2023，45，3： | 3 |
| 2 | Identifying interlinkages between urbanization and Sustainable Development Goals显示文摘Urbanization and Sustainable Development Goals(SDGs)are important global issues in the current“Anthropocene”.Climate change and the COVID-19 pandemic have exacerbated global urban problems and hindered the ability to meet SDGs on time,while the broad interlinkages between urbanization and the SDGs remain poorly understood.This study shows that among the interlinkages of urbanization with 17 SDGs,synergies are observed with 151 targets(89%),among which 67(40%)have stronger synergies,and trade-offs are observed with 66 targets(39%),among which 31(18%)have stronger trade-offs.Furthermore,the synergies and trade-offs between urbanization and the achievement of SDGs are specifically analyzed based on four fundamental interaction fields:(a)public health and social welfare equality;(b)energy consumption and economic growth;(c)natural resource use and ecological/environmental impacts;and(d)international cooperation for development.Finally,based on these analyses,we propose four recommendations for sustainable urbanization,including(a)shared well-being and spatial justice for urban and rural residents;(b)guiding green and low-carbon urban development;(c)building resilient cities;and(d)promoting multilateral cooperation in cities,which can contribute to the achievement of SDGs by 2030. | Mingxing Chen Liangkan Chen Jiafan Cheng Jianhui Yu | 2022 | Geography and Sustainability2022，3，4： | 2 |
| 3 | 城市与气候变化领域国际研究态势分析显示文摘[目的/意义]随着全球气候变化的加剧及城市化进程的加快,城市与气候变化研究已成为全球关注的热点。[方法/过程]基于Web of Science核心合集中的SCIE和SSCI数据库,利用文献计量和主题挖掘方法,分析了城市与气候变化研究领域的国际发展态势。[结果/结论]研究表明,城市与气候变化研究自1991年以来受到了学术界广泛关注,发文量逐年上升,近5年中国的发文量居全球首位。国家/地区间及各机构间合作密切,形成了具有一定规模且较为稳定的研究合作网络。关键词聚类结果表明城市与气候变化研究主要聚焦在五个研究领域:城市气候适应、城市化及其与气候变化的相互作用机制、极端天气、能源及温室气体排放、气候变化对城市居民健康的影响。 | 连迎洁 孙玉玲 张春花 | 2022 | 科学观察2022，17，6： | 1 |
| 4 | Geographical features and development models of estuarine cities显示文摘Cities are the key areas for human beings to achieve sustainable development goals in the future.Estuarine cities are a special type of coastal city in urgent need of a clear definition.This paper proposed that estuarine cities are cities developed on the coast where rivers and oceans meet and defined four connotations,including the intersection of rivers and marine water systems,the coordinated development of land and oceans,the location advantages of connecting rivers and seas,and the important fragility of the ecological environment.We used Hydro SHEDS,OSM,GPW,and urban socioeconomic statistics and selected 50 estuarine cities with large rivers as representatives to summarize the main geographical basis and socioeconomic characteristics.Cities are primarily found in low-altitude,flat regions with average annual temperatures that mainly vary from 10℃to 25℃,relatively abundant precipitation,and extensive biological resources.There are substantial variations in the socioeconomic features of estuarine cities.We proposed eight development patterns,including open and inclusive city spirit,high-quality livable cities,high-quality development driven by innovation,integration of internal and external communication with ports and cities,construction of an international financial center,ecological environment protection and restoration,active promotion of cultural tourism,and positive international exchanges. | CHEN Mingxing XIAN Yue HUANG Yaohuan SUN Zhigang WU Chengbin | 2024 | Journal of Geographical Sciences2024，34，1： | 0 |
