Household structure is an important aspect of family change during China’s modernization process. Existing literature has demonstrated significant associations between various factors and household structure, but the spatial variation in these relationships has not been examined. Using the 2010 Chinese population census data and geographically weighted regression (GWR) model, this study explored the spatial patterns of three-generation lineal households, a functionally important household type in China, and its influencing factors. There was significant heterogeneity in the distribution of three-generation lineal households. Socioeconomic, demographic, and cultural factors were all significantly related to the proportion of three-generation lineal households, but the relationships are place-specific in terms of direction and magnitude. These results suggest that the distribution of Chinese household structures cannot be explained by a single framework of family modernization theory but is determined by the interplay of various local characteristics. Especially, population migration plays an equally important role in affecting household structure than socioeconomic development in China. This work contributes to the family literature by highlighting the spatial heterogeneity in the impact of varying factors on household structure. Beyond the classic modernization theory, it sets a contextualized framework for understanding how Chinese household change in response to the rapid social transformation.  相似文献   

中国中部平原村庄农业生产区位研究——以河南南阳黄庄为例   总被引：11，自引：2，他引：9  

李小建  高更和 《地理科学》2008,28(5):616-623

通过对河南南阳黄庄村农户和农业生产调查以及遥感数据分析,发现人口高密度地区的平原村庄,在耕作半径极小的情况下,存在以住宅和村庄为中心的带状农业区位。从村边向外,可分为蔬菜带、蔬菜粮食混作带和粮食带。相应地,作物的劳动密集度逐渐降低,村地块的蔬菜种植面积比例以及农户微地块单位面积的投入和收益随距村庄距离距离的增加而减少,距离对农户农业生产区位的选择具有重要影响。该结果验证了杜能环在耕作半径较小的中国中部农村的存在,但是造成这种空间分异的根本原因并不是物理交通费用的不同,而是作物劳动密集度和地块肥力的差异,基于一定技术条件下的劳动力耕作能力也有一定影响。  相似文献

从农户土地利用目标变化相关理论出发, 依据在不同经济发展阶段下, 农户土地利用目 标的产量最大化、产量与利润最优化和利润最大化三个阶段的变化特征, 创建了基于农户土地利 用目标变化的“压力- 状态- 效应- 响应”逻辑框架模型; 并据不同经济发展阶段下的“压力- 状态- 效应- 响应”的变化特征, 构建了基于农户土地利用目标变化的耕地质量评价指标体系。这一评价 指标体系的建立为我国在不同经济发展阶段下, 从农户尺度上进行耕地质量保护提供政策依据。  相似文献   

西方城市居住区位决策与再选择模型的评述   总被引：14，自引：2，他引：12  

张文忠  刘旺 《地理科学进展》2004,23(1):89-95

城市居民居住区位选择行为影响着居住空间结构,城市社会分异、种族隔离、人口迁居和住宅郊区化在很大程度上都是居民住宅区位再选择行为作用的结果,因此,研究居住区位对探讨城市内部空间结构等问题具有重要意义。本文主要分析了西方城市居民居住区位再选择行为模型构建的基础和研究视角,并且重点介绍和评述了西方居住区位决策与再选择的主要模型。  相似文献

基于农户视角的耕地细碎化程度评价——以湖北省“江夏区—咸安区—通山县”为例   总被引：4，自引：1，他引：3  

文高辉  杨钢桥  汪文雄  赵微 《地理科学进展》2016,35(9):1129-1143

农户是耕地最主要的经营主体,基于农户视角构建耕地细碎化程度评价指标体系更为合理。本文选取湖北省“江夏区—咸安区—通山县”作为研究区域,采用改进的TOPSIS法,利用农户问卷调查数据,对耕地细碎化程度评价进行了实证研究。结果表明：①耕地细碎化程度衡量指标的选取应基于耕地细碎化的属性特征,从农户微观视角,选取地块平均面积、地块数量、地块间的平均距离3个指标,衡量某一区域的耕地细碎化程度;②耕地细碎化在岗地平原地区与低山丘陵地区间存在显著差异,岗地平原地区的耕地细碎化程度低于低山丘陵地区;③研究区域地形地貌呈现出“北部岗地平原—南部低山丘陵”的分布特征,耕地细碎化的综合程度基本上呈现出“北部低—南部高”的分布规律;④在不同经济发展水平地区耕地细碎化存在显著差异,在岗地平原地区,经济发展水平越高的地区,耕地细碎化程度越高;而在低山丘陵地区,经济发展水平越高的地区,耕地细碎化程度越低。  相似文献

基于中国范围的乡村人居环境调研数据,分析了中国农村宅基地空心现象。结果表明：① 中国农村宅基地空心化严重,93.5%的调研村庄有空心化现象,平均空心化率达到10.2%。② 省域农村宅基地空心化差异明显,其中华北、华东、华中地区普遍较高;③ 多种因素导致农村宅基地空心化,认为是“外出务工”、“户口迁移”、“房屋年久失修”及“一户多宅” 的受访者分别占39.94%,19.51%,25.73%和14.82%。④ 中国农村空心化宅基地再利用潜力巨大,但再利用难度大,需要从改革城乡二元体制和乡村空间重构的角度进行空心村整治。  相似文献   

Town dwellers in their networks: urban-rural mobility and household strategies in Cameroon     

Hélène Mainet 《Geografisk tidskrift / udgivet af Bestyrelsen for Det Kongelige danske geografiske selskab》2017,117(2):117-129

Abstract

Urban-rural interactions are important features of spatial dynamics in Africa that have been affected by recent economic, social and cultural transformations. The attention of academics and policy-makers has concentrated on the impact of such mobility on rural actors and economies. Our objective is to consider the point of view of urban households and to analyse how they manage to develop and use their “rural connections”. The paper is based on in-depth qualitative fieldwork conducted in Cameroon, in Douala and Bafoussam. It presents an analysis of the configurations of urban resident mobility to rural regions. By mapping mobility we show the role of linkages with rural areas in urban household strategies. We also illustrate how a major city and a fast-growing secondary one differ in their connections with rural areas. The paper addresses what is one of the recurrent questions in the literature: will urban-rural linkages change in the long-term as the trend towards urbanization intensifies. Urban-rural mobility remains crucial, contributes to creating complex and dynamic networks. Collective connections are reaffirming the importance of the village and the region of origin. Mobility is a key element for many urban households in developing their urban position and strategies.  相似文献

Access to natural resources and conflicts between farmers and agro‐pastoralists in Borkena Wetland,north‐eastern Ethiopia     

《Norsk geografisk tidsskrift. Norwegian journal of geography》2012,66(3):97-112

This case study on the Borkena wetlands in north‐eastern Ethiopia tells, through the voices of the inhabitants, the story of the occupation and management of an area where agro‐pastoralists (Urrane) and farmers have progressively settled. It shows how different policy changes and natural disasters have transformed the type of peoples' livelihoods and land use patterns in the wetland. It tells the history of relationships between smallholder peasants, irrigation farmers, commercial farms, and the Urrane, where conflicts as well as collaboration developed, and it shows how different stakeholders behave and consider their own situation. The study also reveals that development intervention by World Vision Ethiopia (WVE) had mixed impact on peoples' livelihoods in the wetland: sedentary peasants have benefited while the Urrane have been adversely affected. The main issue is the marginalization of pastoralists, with the denial of their traditional land use rights by three successive regimes and administrations. Any solution to the cohabitation of the different groups and livelihoods will have to address the issue of land rights for the pastoralists and promote the fair participation of all stakeholders in the future management of the wetlands. Good governance and the competence of the state actors at local levels are the crucial issues for the realization of the suggested solutions.  相似文献
