SUSTAINABLE URBAN-RURAL RELATION IN RAPID URBANIZATION AREAS——Case of Transformation of "Urban Village" in Guangzhou

Many studies have been made concerning the problems, characteristics, formation, transformation measures, etc. of urban village from sociology, urban planning and geography, etc., which have made insightful analysis. However, most of these studies started mainly from the standpoint of the city govemment, drumming for the land- scape-oriented urbanization, namely pulling-down the urban village and constructing the splendid residence or business buildings. The article maintains that the most important thing the city government should do is to pay much attention to the sustainable living of urban villagers, who would lose their main income source, namely, the collective dividend and the family housing rent. The single method of compensation has been proved to be harmful to the villagers＇ community, in which some young villagers relying on rent were no longer to do anything but stay at home. On the other hand, considering the floating population has become the main stream of renters in urban villages, the emergence of urban villages was inevitable and would continue to exist in a long time under the socio-economic transition in urban China and globalization. Based on the analysis above, the transformation of urban village should take more concerns on the housing demands of floating population besides compensation for local villagers. Meanwhile, it is necessary to avoid the “landscape-oriented urbanization” without the “peasant-to-citizen” transformation.

Spatiotemporal Evolution and Influencing Factors of Urban-rural Construction Land in Rural Industrialized Areas in China:Case Studies in Changyuan City and Xinxiang County of Henan Province

Since China’s reform and opening up in 1978,the acceleration of industrialization and urbanization in China had led to dramatic changes in the pattern of urban-rural land use.In this paper,we focused on the rural industrialized areas in central China(Xinxiang County and Changyuan City of Henan Province).We used the average nearest neighbor index,spatial statistical analysis,and a structural equation model to analyze the spatiotemporal evolution and influencing factors of urban-rural construction land based on multisource spatial data and survey data.The results showed that:1)from 1975 to 2019,the spatial distribution of urban-rural construction land in rural industrialized areas had evolved from homogeneous distribution to local agglomeration.In terms of comparative analysis of cases,the spatial distribution of urban-rural construction land in Changyuan City had shown a trend from diffusion to agglomeration,and Xinxiang County had overall shown a spatial change from homogenization to agglomeration and then to regional integration development.2)The hot spots with increased urban-rural construction land significantly expanded,and they had a high degree of spatial overlap with industrial development.Among them,Xinxiang County was concentrated in central and marginal areas,and Changyuan was mainly concentrated in central urban areas.3)From the evolution of spatial proximity of urban-rural construction land,rural industrialized areas generally decline,showing the characteristics of internal differentiation in the rate of change.4)Industrial development,social economy,the policy environment,and urban development played a positive role in promoting the expansion of urban-rural construction land in rural industrialized areas.To promote the optimal use of regional land and the integrated development of urban-rural areas,we should combine the advantages of regional endowment,formulate development strategies according to local conditions,and adjust the way that land is used in a timely manner.

An investigation of the health value and self-care capabilities of the elderly in urban-rural fringe area nursing homes and the related in？uencing factors

Objective：To investigate the health value and self-care capabilities of the elderly living in urban-rural fringe area nursing homes and the factors that influence these variables.Methods：A cluster sampling method was used to select 280 elderly individuals from seven urban-rural fringe communities in Xianning to complete a survey regarding their health value and self-care capabilities.Results：The total health value and self-care capability scores of the elderly were 7.45 ± 1.45 and100.25±22.56,respectively.Both of these scores significantly differed by age,education level,marital status,and income（P 〈 0.05,P 〈 0.01）.Self-care capability was correlated with health value（r=0.521）.A multivariate linear regression analysis showed that health value,marital status,and age predicted selfcare capability.Conclusions：Elderly people living in the urban-rural fringe area with higher health values also had higher self-care capabilities.The self-care capabilities of the elderly can be enhanced by improving their health value using the ＂knowing-trusting-acting＂ model.

Overall Planning of Development of Urban-Rural Areas:A Policy Mechanism for Urban-Rural Coordinated Growth

While analyzing overall planning and coordinated development of urban-rural areas, this paper shows that overall planning for the development of urban-rural areas is a requirement for the best use of productive forces. It means the setting up of a policy mechanism for coordinated growth. Recognizing this, the government should set up a way to lead and manage a unified program to increase service and decrease controlling administration power, while safeguarding and fulfilling the farmers' ownership to the means of production.

On the modes of urban-rural networking development in China

This essay tries to reveal the developmental regularity of urban-rural networking manifested by urbanization. The urban-rural networking is a reality and an inexorable trend of development. As a physical existence, the urban-rural networking reflects a result of the interaction between cities and rural areas; it is a necessary and sufficient condition for sustaining progress of cities and rural areas. As an objective developmental tendency, it reflects an urban-rural regional economic process. The author briefly analyzes two contradictory urban-rural developmental views, and puts forward a concept of the mode of urban-rural networking development. The author also analyzes the mode from the perspectives of economics and philosophy.

国家公园联动发展区宅基地盘活的模式选择:基于群体利益异质性的视角

研究目的:基于群体利益异质性视角,通过比较百山祖国家公园联动发展区内两个典型村庄的特征,辨析经济和社会利益异质性对宅基地盘活的农户自组织模式与政企合作模式选择的影响,为因地制宜选择国家公园联动发展区宅基地的盘活模式提供科学依据。研究方法:案例分析法、比较分析法。研究结果:(1)群体利益异质性所引致的选择性激励能促成宅基地盘活的集体行动;(2)资源禀赋、群体规模、人口流动频率的村庄特征影响群体利益异质性程度;资源禀赋较好、群体规模较小、人口流动频率较低的村庄经济和社会利益异质性较强,资源禀赋较好、群体规模较大、人口流动频繁的村庄经济利益异质性较强但社会利益异质性较弱;(3)经济和社会利益异质性均较强的村庄更容易形成农户自组织的宅基地盘活模式,经济利益异质性较强但社会利益异质性较弱的村庄则适用政企合作模式。研究结论:群体利益异质性是影响国家公园联动发展区宅基地盘活模式选择的关键因素。单一的强经济利益异质性不足以促成宅基地盘活的集体行动,还需发挥社会利益异质性对农户的内生激励作用,更好地落实国家公园全民共建共享的发展理念。

Measuring the past 20 years of urban-rural land growth in flood-prone areas in the developed Taihu Lake watershed, China

There is growing interest in using the urban landscape for stormwater management studies, where land patterns and processes can be important controls for the sustainability of urban development and planning. This paper proposes an original index of Major Hazard Oriented Level （MHOL） and investigates the structure distribution, driving factors, and controlling suggestions of urban-rural land growth in flood-prone areas in the Taihu Lake watershed, China. The MHOL of incremental urban-rural land increased from M 31.51 during the years 1985-1995 to M 38.37 during the years 1995-2010 （M for medium structure distribution, and the number for high-hazard value）. The index shows that urban-rnraI land was distributed uniformly in flood hazard levels and tended to move rapidly to high-hazard areas, where 72.68% of incremental urban-rural land was aggregated maximally in new urban districts along the Huning traffic line and the Yangtze River. Thus, the current accelerating growth of new urban districts could account for the ampliative exposure to high-hazard areas. New districts are driven by the powerful link between land financial benefits and political achievements for local governments and the past unsustainable process of ＂single objective＂ oriented planning. The correlation categorical analysis of the current development intensity and carrying capacity of hydrological ecosystems for sub-basins was used to determine four types of development areas and provide decision makers with indications on the future watershed- scale subdivision of Major Function Oriented Zoning implemented by the Chinese government.

干旱区新型农业经营主体与农户利益联结模式效果评价研究

研究干旱区新型农业经营主体与农户利益联结模式效果,有利于促进农户收入的增加、小农户与现代农业的有机衔接,并进一步发挥其带动作用。从经营效果、治理效果、发展效果维度构建利益联结模式效果评价指标体系,运用主客观分析法确定指标综合权重,通过TOPSIS法,对干旱区最常见的股份式或股份合作式、企业化式、订单合同式利益联结模式作实证分析,同时利用障碍因子诊断模型,探讨利益联结模式效果的主要影响因子。结果显示,股份式或股份合作式的贴近度最大,为0.678,企业化式的贴近度次之,为0.640,订单合同式的贴近度最低,为0.253。从准则层权重来看,经营效果权重较大,治理效果、发展效果的权重相当。培训情况、农业收入增长率、二次分红、机械化水平、覆盖农户数、产业融合程度是影响利益联结模式效果的重要因素。鉴于此,提出干旱区政府应加大股份式或股份合作式的利益联结机制的推行力度,提高农户的成长能力,增强经营主体的盈利能力等对策建议。
