乡村生产空间系统演化的逻辑认知及数理表达

乡村生产空间系统健康有序运行是实施乡村振兴、营建人与自然和谐共生的物质基础和载体,精准控制系统由低级有序向高级有序发展是关键。综合社会学、哲学、系统学和地理学等多学科理论,建构乡村生产空间系统演化的逻辑认知概念模型,对其演化的逻辑起点（人地关系）、逻辑顺序（时间、空间和流三维分析）以及流驱动机理进行质性研究,探寻乡村生产空间系统演化的内在本质;借鉴耗散结构理论和熵变理论,构建乡村生产空间系统演化熵变模型并作出相关释义,为研究人地关系系统演化提供思路,以丰富和拓展乡村地理学的理论。     

农户的非农就业如何影响中国的土地流转?

To clarify the impact of non-agricultural employment on rural land circulation in China,we built logit models using the Chinese Household Income Project 2013 dataset,which includes 18,948 household samples over 15 provinces,126 cities and 234 counties of China in 2013.We use the proportion of non-agricultural income,the proportion of non-agricultural laborers and non-agricultural fixed operating assets to reflect the degree of the households’dependence on agriculture,the degree of the households’laborers committed to non-agricultural employment and the stability of non-agricultural employment,respectively.The results show that the stability of non-agricultural employment is an important reason for farmers to transfer out their land,and an increase in non-agricultural income is the fundamental reason.The proportion of non-agricultural assets has the greatest impact on the decision to transfer land,followed by the proportion of non-agricultural income.Per unit increase in the non-agricultural income ratio has a stronger effect on the transfer-out decision than it does on the transfer-in decision,which is a 0.09 increase of the probability of transfer-out the land and a 0.07 decrease of the probability of transfer-in the land.In terms of regional differences,when considering the impact of non-agricultural employment on the land transfer-out decision,the impacts of non-agricultural income and labor force are the greatest in the Central region.The impact of non-agricultural assets is the greatest in the Eastern region.For the Eastern region,the decision to transfer out land is mainly affected by non-agricultural assets and the non-agricultural labor force,and the decision to transfer in land is mainly affected by non-agricultural assets.In the Central and Western regions,the decision to transfer out land is mainly affected by non-agricultural assets,non-agricultural income and the non-agricultural labor force,in that order.The decision to transfer in land in the Central region is not significantly affected by non-agricultural employment.The decision to transfer in land in the Western region is mainly affected by non-agricultural assets,non-agricultural labor force and non-agricultural income,in that order.We note that non-agricultural assets have a prominent impact on land transfer,which shows that the stability of non-agricultural employment has an important impact on land transfer decision-making.Vocational training for rural labor forces may be an effective means to promote stable non-agricultural employment and simultaneously facilitate rural land circulation,especially in Central and Western China.

Space Changes in the Rural Tourism Area of Mufu Town,Hubei Province,China

In a society dominated by tourism consumption, space changes occurring in rural areas can generally reflect their social changes. On the theoretical basis of flow, regeneration and adaptation of rural tourism space, this paper originally and creatively proposes that the spatial elements in a rural tourist area can be classified into three categories: Attractions (A), Towns (T) and Villages (V). By analyzing the spatial transformation characteristics of A, T and V, five types of rural spatial transition modes are found, the types of heritage, theme park, those serving as scenic spots, leisure industrial clusters and ecotourism areas. These different classes emerge due to their geographical differentiation. They show the same spatial evolution trend: The Attractions are distributed throughout the whole area and characterized by diversification; supporting services facilities gather in the Towns; and the Villages are landscape images. In this area the traditional rural benefit trends toward that of compound development. Mufu Town, Hubei province, is taken as a study case, and the changing characteristics of A, T and V from 2006 to 2016 are described. Problems in the process of establishing the new spatial order are considered. In order to realize the synergy between production space, living space and ecological space, the interactive development between Attractions, Towns and Villages is recommended. The perspective of Attraction-Town-Village (ATV) can lead to a better understanding of the situation of tourism space in rural areas and provide directions for thinking about the reconstruction path for the modernization of traditional societies.

Youth Mobility and Territorial Disparities: An Analysis of Urban and Rural Barcelona

Travel behavior of the present generation of youths is being increasingly explored due to their relevance in shaping future accessibility needs and mobility habits. The present study offers an original perspective on this topic by identifying territorial disparities that emerge in youth mobility patterns in rural and urban areas. Unlike most previous research, we propose taking a global view on mobility by analyzing all trip purposes and transportation modes. This is conducted by analyzing a comprehensive mobility survey in the Barcelona Metropolitan Region, which provides data on mobility engagement, trip purposes, modal split, travel times and territorial differences. In general, youngsters account for larger daily travel times than older adults, present a higher attachment to public transportation and walk less on a daily basis. These differences are enhanced in rural territories, where while older adults overcome accessibility issues with higher use of the private vehicle, youngsters are more likely to invest larger travel times on transit.     

The Three American Wests

In the twenty-first century, there are three American Wests, which cut across cultural, political, physical, and economic boundaries. Parts of the West are booming, building homes, and adding population; others are legally off limits to such development; and much of the West has been bypassed by such development and growth. These are called here the Booming West, Protected West, and Bypassed West. Maps of climate, political boundaries, ethnic and racial identities, or presidential voting patterns do not match these three Wests. Each West has a different relationship to the others and might see them as threats or opportunities, and each West can be expected to grow in different areas at the expense of other Wests. The boundaries between the three Wests could be important locations; sharp transitions can exist between Wests, perhaps nowhere more so than where a fast growing metro area abuts a national park or forest boundary. Finally, the effects of climate change cut across the three Wests and have different implications for their future. Continued population growth will further emphasize the boundaries between each of the three Wests and raise the stakes for their control.     

黄淮海地区乡村人—地—业协调发展格局与机制

乡村在社会中占有重要地位,但乡村衰败目前已成为世界性问题,因此,乡村振兴需破解乡村病问题。现有乡村研究主要关注乡村单一系统、乡村转型或乡村特定问题的研究,对乡村系统自身、乡村各子系统之间关系及其驱动乡村发展逻辑的研究则显匮乏。基于黄淮海地区县域数据,选取乡村人—地—业3个子系统,利用耦合协调度模型刻画了乡村内部系统耦合协调度的空间格局,并对人—地—业驱动乡村发展的内在逻辑进行了探讨。结果发现：① 黄淮海地区大部分县域乡村人—地—业发展处于高水平耦合阶段,在空间格局上形成了4条明显的高值轴带,且乡村系统发展水平呈逐年上升趋势。② 黄淮海地区乡村耦合协调水平整体较高,但大部分处于勉强协调或初级协调阶段,耦合协调水平较高的县域主要集中在经济较发达地区。③ 黄淮海地区乡村耦合协同关系可分为低协调水平—土地发展领先型、中协调水平—人口发展领先型和高协调水平—人业发展引领型3种类型,其中产业在黄淮海地区乡村协调发展中至关重要。④ 乡村人—地—业的协调发展可有效激活“四力”,为乡村可持续发展奠定了基础。本研究为理解乡村系统自身、破解乡村问题及实现乡村可持续发展提供了参考。
