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.  相似文献

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.  相似文献

黄淮海地区乡村人—地—业协调发展格局与机制   总被引:8,自引:0,他引:8

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。  相似文献

Using in-depth interviews with women engaged in sustainable farming in the western United States, this project explores an unanticipated finding: migration from an urban area to rural “Prairie County” was necessary for these farmers to secure farm land and sustain their farming operations. This article interrogates the role of migration in women’s access to farmland as both an economic and cultural phenomenon. My findings highlight the necessity of migration for women’s participation in sustainable farming and suggest that women’s success in sustainable farming may align with the processes of rural gentrification, by which cultural and economic in-migrants amplify their social privilege and transform the values and economy of rural communities. This project, then, situates gender as a key structure to understanding both the classed dynamics of sustainable agriculture and rural gentrification.  相似文献

The term “working landscape” (WL) is increasingly used by American planners and policy makers to describe the rural places and livelihoods they aim to shape. This paper draws from a mixed-methods study of WL language as a collective action frame in the state of Vermont, where WL has been formalized into policy. Natural resource leaders and professionals share a common definition of WL that is supported by four key beliefs. However, interviews conducted in two representative farming communities suggest that landuse practitioners have not adopted WL language, and in some cases are skeptical of its meaning. The analysis explores potential explanations for the failure of the WL collective action frame to resonate across scales. The paper argues for a bottom-up planning approach that produces working landscapes policies that allow for diverse forms of work and accommodate the specificities of place.  相似文献

This article explores the suitability of Ostrom and colleagues' social-ecological systems framework (SESF) for the study of resource-dependent communities in Canada. Through a broad literature about resource-dependent communities in Canada, three main approaches are identified, named staples research, rural development, and sustainability studies. Each of these research traditions is analyzed with regards to a common set of criteria – focus, scale, methods, treatment of institutions, and treatment of environmental dimensions. Research in each category is compared and contrasted with the SESF approach, to identify areas of overlap and divergence. Results indicate that the SESF is unlikely to provide additional benefit in terms of in-depth of social analysis, however, it does provide a unique contribution in terms of its coupled approach to conceiving social and ecological systems and its ability to operationalize these relationships through structured variables.  相似文献

Abstract

Tenure security is commonly recognized as an important factor in stimulating long-term investments in land. Recent studies suggest that a distinction between legal, actual and perceived tenure security needs to be made in analyzing tenure security. This study discusses the relationships between legal, actual and perceived land tenure security in rural China, and empirically examines the impact of actual on perceived land tenure security by applying Probit models to household and village survey data collected in four provinces. Using household expectations about the absence of land reallocations within the next five years as the dependent variable, we find that tenure security is positively affected by the possession of land certificates in villages that periodically reallocated land but not in villages that did not do so. The estimated impact is larger for land certificates issued in the new round of land certification than for land certificates that were issued earlier.  相似文献

基于耗散结构系统熵模型的乡村生产空间系统有序性研究   总被引:2,自引:0,他引:2  
通过分析乡村生产空间系统的耗散结构特征,建立系统熵模型,运用关联熵和运行熵,从系统的主体(多元主体)、客体(地)和环境三要素入手构建指标体系,讨论系统内部结构和运行状态的有序性,并以重庆市合川区龙市镇为研究区予以实证,研究表明:研究区乡村生产空间系统关联熵先增后减,系统内部结构有序性呈现阶段性特征,2008—2011年主要受城市化无序扩张和土地利用方式低效粗放等因素影响,系统内部结构趋于混乱无序,2011—2015年主要因财政支农力度增强、农业投入产出水平提高、生态修复力度加大等因素刺激,系统内部结构逐渐趋于有序化;2008—2015年,乡村生产空间系统运行熵逐年减小,在农业综合开发投入大幅增加引起的生产条件改善、产业结构调整与提档升级等驱动下,呈现出持续有序化的发展态势;围绕乡村生产空间系统的内部结构及运行状态的演化规律,从优化土地利用结构、构建现代农业产业体系、编制和完善相关规划、培育新产业新业态入手,提出相关策略,以促进乡村生产空间系统有序健康发展。  相似文献

乡村振兴战略是新时期我国推进城乡融合发展的重要举措。贫困地区既是脱贫攻坚的主战场,又是乡村振兴的重点区域。如何科学识别村落类型,分类推进典型区域乡村振兴发展,对于破解农村发展不平衡不充分问题具有重要的现实意义。本文解析了乡村地域系统发展理论,阐释了城乡融合发展理论,剖析了村域空间结构格局演变和城乡要素结构功能优化重组;构建了西北干旱贫困地区乡村振兴村落类型识别体系,从乡村主体、产业发展、人居环境、资源禀赋4个子系统进行逐级分类判断,识别乡村主导类型,结合专家征询分析与村落特征,将乡村振兴村落类型识别为集聚提升类、三产融合类、城郊融合类、特色保护类、搬迁撤并类,结合不同乡村振兴模式提出了相应地发展路径,以期为乡村振兴提供理论依据与决策参考。  相似文献

乡村旅游地面临人地交互作用的剧烈变迁,内部要素适应社会-生态系统变化,趋利避害降低脆弱性具有重要现实意义。本文重新界定基于恢复力和脆弱性的农户适应性理论内涵,构建旅游开发适应力指标体系,以西安市和咸阳市17个不同类型的城郊型乡村旅游地为例,评价和分析农户旅游适应效果与空间差异规律,探讨和归纳适应行为与对策模式,建立BP神经网络辨别和揭示适应性影响因素与重要性关系。研究表明:① 西安市和咸阳市农户适应旅游开发综合效果呈现中等偏下水平的偏态分布趋势,分别处于旅游地生命周期快速发展阶段和探索起步阶段。② 乡村旅游地农户适应效果形成“圈层辐射、两翼包络、外围联动”的县域尺度空间分布格局;村域尺度圈层分化现象显著。③ 经营模式划分的旅游乡村农户适应效果股份制模式>“公司+农户”模式>“政府+公司+农户”模式>个体农庄模式>“农户+农户”模式;常年外出务工和农家乐经营是农户主要适应行为选择,季节性务工、本地上班以及农业生产是辅助适应行为选择,且适应行为组合方式表现为旅游专营型、旅游主导型、均衡兼营型、务工主导型和务农主导型五种适应对策模式。④ 旅游发展机会认知、技能培训机会、社会联结度、劳动力总量、政策知晓度、旅游就业人数、收入来源种类、生活主要能源、受教育程度、公共服务设施是农户主要旅游适应性影响因素。据此,提出后续社会-生态整合研究亟需突破方向和适应旅游开发的政策路径。  相似文献
