“特色全球城市”目标下的新加坡河滨水空间再生与启示

本文尝试在新加坡经济发展与转型的基本背景下,理解新加坡建设“特色全球城市”的目标;探讨在该目标的驱动下曾一度衰落的新加坡河滨河区如何实现空间功能的转变与再生,成为兼具社会开放性与包容性、全球化与本土化的空间载体,并推动新加坡城市的可持续发展与“特色全球城市”目标的实现;最后总结了其对于“建设美丽中国”目标下中国城市滨水空间开发的借鉴与启示。     

体育与地理空间的国内研究进展

基于对国内文献的搜集和整理,从体育的内涵辨析和学科演进梳理着手,对体育人才、体育产业、体育活动以及体育场地与地理空间的关系4 个方面进行综述。研究发现：体育人才、体育产业、体育活动和体育场地均具有很强的地理特征和空间指向性,体育人才与地域文化和历史关系密切,体育产业受基本经济地理格局深刻影响,体育活动具有明显空间差异特征;体育场地是城市空间的重要组成部分;体育学科内涵在持续拓展,与地理学的交叉将是一个重要机遇;人文地理学在学科综合、关注视角、研究方法和技术手段等方面具有较好的学科优势,能够很好地参与体育研究,推动体育现象的全景揭示和深度解析。     

中国城市居民住房来源构成与省际差异——基于“五普”与“六普”数据的分析

2000年到2010年十年间,随着中国城市住房改革的深入和住房市场的快速发展,城市居民住房来源结构也发生了较大变化。本文综合不同视角对当前中国城市居民住房来源体系进行了梳理,选取购买商品房、购买经济适用房、租赁住房和自建住房4种类型,以第五次人口普查和第六次人口普查的数据为基础,分析了中国31个省(市、区)城市居民住房来源的构成、变化和省际差异特征,并通过构建神经网络对省际差异的影响因素进行分析。最后得出结论并对未来城市居民住房结构的变化进行展望。     

Spatial characteristics and driving forces of the morphological evolution of East Lake,Wuhan

The shapes of the urban lakes in Wuhan city have been strongly influenced by the rapid industrialization and urbanization experienced in recent decades.Based on topographic maps and remote sensing images,the temporal and spatial changes of East Lake,Wuhan city,over the past two decades were analyzed.The landscape shape index(LSI)and centroid method were applied to analyze the evolution of lake morphology and its causes.Several key results were obtained.(1)The surface area of East Lake decreased sharply by 2.13 km2 from 1995 to 2005,and slightly by 1.00 km2 from 2005 to 2015.The shoreline length of East Lake displayed a continuous trend of decline during the study period:The length reduced by 21.89 km from 1995 to 2005,and by 0.67 km from 2005 to 2015.The LSI values,7.04(1995),6.46(2005),and 6.28(2015),displayed an accelerated downward trend,indicating a reduction of complexity in East Lake and the intensification of manual interventions in the water body.(2)The changes to East Lake displayed a clear temporal and spatial heterogeneity.The centroid of East Lake moved northeast from 1995 to 2005 and southeast from 2005 to 2015.(3)The reduction in the area of East Lake was mainly affected by human activities.A lake area of about 4.8 km2 was converted to other land uses during 1995-2005,most of which was unused land,whereas from 2005 to 2015,0.43 km2 of the lake area was converted into built-up land,and 0.25 km2 was converted into other land uses.The reduction in area was caused by infrastructure construction by the government,the development of the real estate industry,illegal construction by villagers,and the development of scenic spots for tourism.The driving forces of this reduction included Wuhan's growing population,and the rapid development of the economy and urbanization between 1995 and 2015,which has resulted in a large demand for land.Finally,a formation mechanism model was constructed by analyzing the causes of East Lake's morphological evolution.
