广州保障性住区的社会空间特征

城镇保障性住房制度直接塑造了保障性住区,这一“国家化”的社会空间在不同的城市呈现出迥异的类型。通过梳理城镇保障房制度的演变及在广州的实施,将广州的保障性住区分为四类:1986～1998年建成的承接单位体制内住房困难户的住区、1999～2005年建成的承载党政机关和教医系统住房困难家庭的住区、2006年后新建的主要承载具有城市户籍的社会双困群体的住区、建设历程跨越多制度阶段的承载多类保障群体的综合住区;通过“典型案例”研究,各类保障住区的现状社会空间可归纳为:“类西方‘社会型’公共住区的极度贫困均质空间”、“介于中国城市普遍存在的贫困集聚区的‘贫困混杂空间’和西方混合社区的‘有序混合空间’之间但混杂性高的贫困空间”、“介于两者之间但有序性强的混合空间”、“类商品房住区”的均质非贫困空间。

水危机”是否影响“经济繁荣”

正早在1996年联合国关于城市问题的第二次人类住区大会上,水就被定义为"2l世纪国际社会争论最激烈的城市问题"。这个听起来像是来自罗马俱乐部的预言,被不幸言中。如今的中国,一方面持续的旱情令河流干涸、土地龟裂,另一方面污染使人守着江河湖泊却无水可饮。中国经改革开放近三十年发展,在经济发展的同时,神州大地满目疮痍,尤     

干旱内陆河流域人居环境适宜性评价——以石羊河流域为例(英文)

The study employs slope,aspect,relief degree of land surface,land use,vegetation index,hydrology and climate,as evaluation indexes to set up the Human Settlements Environmental Index(HEI) model to evaluate the environmental suitability for human settlements in the Shiyang River Basin.By using GIS spatial analysis technology,such as spatial overlay analysis,buffer analysis and density analysis,the environmental suitability of the human settlement spatial situation and spatial pattern are established to analyze their spatial distribution.The results show that the index of suitability for human settlements in the Shiyang River Basin is between 17.13 and 84.32.In general,suitability for human settlements decreases from the southwest to the northeast.Seen from an area pattern,the suitable region is mainly distributed in the Minqin oasis,Wuwei oasis and Changning basin,which are about 1080.01 km 2 and account for 2.59% of the total area.Rather and comparatively suitable region is mainly distributed around the counties of Gulang,Yongchang and north of Tianzhu,which is about 1100.30 km 2.The common suitable region is mainly distributed outside the counties of Yongchang,Jinchuan and most parts of Minqin County,which are about 23328.04 km 2,accounting for 56.08% of the total area.The unsuitable region is mainly distributed upstream and to the north of the river,which is about 9937.60 km 2,accounting for 23.89% of the total area.Meanwhile,the least suitable region is distributed around the Qilian Mountains,which are covered by snow and cold desert and lie in the intersecting area between the Tengger Desert and Badain Jaran Desert.The total area is about 6154.05 km 2,accounting for 14.79% of the total area.Suitable regions for human habitation are mainly distributed around rivers in the form of ribbons and batches,while others are scattered.The distribution pattern is identical to the residential spatial pattern.In addition,the relationships between HEI and other factors have been analyzed.There is a clear logarithmic correlation between the residential environment and population,that is,the correlation coefficient between the evaluation value and population density reaches 0.851.There is also a positive correlation between the residential environment and economy,which reaches an evaluation value of 0.845 between the residential environment and GDP.Results also show that the environment is out of bearing with the existing population in Shiyang River Basin.Spatial distribution of population is profoundly affected by severe environmental problems,such as the expanded deserts,the hilly terrain and the changing climate.Surface water shortage and slow economic growth are bottlenecks for suitable human settlement in the Shiyang River Basin.Combining these problems with planning for construction of new country and the exploitation of local land,some residential areas should be relocated to improve the residential environment.     

村镇住区选址评价探讨

根据对国内外村镇住区选址影响因素的综合分析及实际调研,认为影响村镇住区选址的主要因素是地质、地形地貌、水源、生态环境、耕作半径、区位和对外交通等。基于此,选取了由18项指标层、8项准则层和1项目标层构成的递阶层次结构村镇住区选址评价指标体系,运用层次分析法确定指标权重,采用加权平均法计算村镇住区选址评价综合指数,将村镇住区选址类型区分为适宜区、较适宜区和不适宜区三种,并以案例对村镇住区选址评价指标体系进行具体应用。     

住区环境对居民主观幸福感的影响机制研究——以深圳混合居住区为例

随着中国特色社会主义新时代人民对美好生活的向往与日俱增,配建房居住群体作为一类“夹心层”群体,其住区环境和主观幸福感理应得到充分重视。论文以深圳市混合居住区为例,揭示配建房住区环境对居民主观幸福感的影响机制。针对3个典型住区开展问卷及访谈调研,并构建结构方程模型,将地方感和房屋类型分别作为住区环境影响居民主观幸福感的中介变量和调节变量。研究结果表明：(1)总的看,住区环境对居民主观幸福感具有显著的直接影响;分维度看,社会环境对主观幸福感具有直接影响,而建成环境中,小区环境、社区环境和住房环境对主观幸福感影响均不显著;(2)由中介效应看,社会环境通过建立居民地方感间接影响主观幸福感;(3)由房屋类型看,相较保障房住户,人才房住户主观幸福感受社会环境影响强度更大。综合来看,研究结果能够为完善配建房制度提供科学决策支持。     

IPCC AR6报告解读：气候变化对城市、住区和关键基础设施的影响与适应

IPCC AR6 WGII评估了气候变化对城市、住区和关键基础设施的影响、风险及应对。气候变化对城市影响的程度和范围逐渐增加,全球城市化的过程与气候变化相互作用加剧了城市和住区的风险。通过社会基础设施、基于自然的解决方案和灰色/工程基础设施所采取的适应措施对气候恢复力发展均有贡献,而城市适应差距在世界各地普遍存在。气候恢复力发展需要多方协作、弥合政策行动差距、提升适应能力。评估报告的经验和案例为我国城乡地区适应和应对气候变化风险提供借鉴。     

城市中心区停车泊位对既有住区工作日夜间共享能力评价 ——以天津市和平区为例

针对城市中心区既有住区停车泊位资源紧缺的问题,以天津市和平区居住、商业、办公及医院用地停车泊位为样本,基于城市中心区既有住区工作日夜间停车需求与周边其他用地类型停车资源的时空供需匹配及居民对不同类型停车资源步行距离容忍度差异,改进步行指数方法,构建停车资源共享能力评价模型,定量分析停车泊位的共享能力。结果表明:天津市和平区停车共享性分布不均匀,不同用地类型停车泊位共享能力与共享泊位数量和其服务的居民户数相关性高,与路网密度相关性较低。
