随着乡村振兴战略的提出,乡村绿道作为绿色线性
空间建设的抓手越来越受到政府重视。但在现有技术条件的
指导下,乡村绿道建设成效往往表现出明显的单一性与不协同
性。为此,引入协同学理论,在分析现有绿道研究水平的基础
上,指出乡村绿道规划需达到多功能协同与多因子协同,建立
了以生态、文化、游憩、产业4个功能为子系统,以连通性、
可达性、适宜性为序参量的乡村绿道协同评价体系,定量分析
各功能子系统间的协同作用和乡村绿道整体的协同程度,从而
提出乡村绿道规划方法和应用途径,并以嘉善县大云镇乡村绿
道规划为例,应用协同评价模型进行实践应用验证。 相似文献

为促进乡村经济繁荣、巩固边疆生态安全屏障,尝
试将边疆乡村生态旅游与绿道概念结合,构建边疆乡村生态旅
游绿道体系,而绿道的规划选线是乡村生态旅游绿道建设的关
键。为探究边疆乡村生态旅游绿道选线的内在机制,在研究有
关乡村生态旅游绿道文献和场地调研的基础上,提出了坤河达
斡尔族满族乡生态旅游绿道的构建模式,并在Yaahp、GIS软
件的辅助下,选取生态旅游适宜性、景观游憩适宜性和绿道资
源适宜性作为选线要素,进而确定选线因子。利用层次分析法
(AHP)、德尔菲法(Delphi)和模糊层次分析法(FAHP)构建
乡村生态旅游绿道适宜性评价模型,并借助ArcGIS平台计算
选线方案,对绿道选线进行修正和优化。研究发现:1)最适宜
新建的生态旅游景观节点是异域风情观赏点;2)绿道适宜在已
有道路两旁建设;3)边疆乡村生态旅游绿道选线应遵循最小路
径成本、线路闭合性和体系化原则。 相似文献

绿道作为城市建设的新理念,适应了低碳城市的发展要求。绿道具有线性联系、公共游憩及投入少见效快等特点,在生态保护、旅游发展和宜居城乡建设方面起到积极的作用,因此在中小型生态旅游城市拥有广泛的应用前景。提出中小型生态旅游城市建设绿道的策略,并以仙居县绿道规划设计为例,从规划定位、绿道分级分类、规划结构以及示范段的详细设计等方面,系统总结了实践经验,以期对同类型城市提供借鉴。 相似文献

Urban greenways play a key role to a city’s nonautomobile commuting and help alleviate traffic congestion. Currently, China’s greenway planning research and practice focuses mostly on suburban areas where greenways provide ecological, historical, cultural, and recreational services, while fewer studies explore urban greenways that serve citizens’ daily non-automobile commuting and recreational needs. Compared with suburban ones, urban greenways often face more spatial limits in the built-up areas and need to respond to more challenging demands. Supported by multisource data and the rise of big data technologies, this research explores the methods of urban greenway route planning that are underpinned through GIS spatial analyses (potential evaluation on spatial construction conditions of greenways) and big-data-based user behavior analyses (of citizens’ daily use of greenways). Demonstrating the authentic planning case for Haidian District, Beijing, the research proposes a series of construction strategies to urban corridors of roads, waterways, and railways, respectively, which integrate green spaces with non-automobile system, in order to improve the services of linear spaces in cities. 相似文献

Urban landscape conservation and the role of ecological greenways at local and metropolitan scales 总被引:7,自引:0,他引:7
Greenways are promoted for land conservation in both rural and urban areas, but less attention has been paid to the potential of greenways to serve urban biodiversity conservation goals. This paper presents results of a biodiversity planning study of a highly urbanized environment in Washington, DC (USA) that demonstrate the critical role of ecological greenways and parks in urban species conservation. The Cameron Run study raises fundamental questions about the way biodiversity is defined in urban areas, the scale of analysis required in heterogeneous urban environments, the role of sociocultural factors in urban biodiversity conservation, and the importance of regional greenway connections across the urban gradient.The Cameron Run study is a pilot project for an urban biodiversity information node (UrBIN) in the National Biological Information Infrastructure (NBII) program of the US Geological Survey (USGS). This paper draws connections between the rapidly expanding literature on biodiversity conservation and the smaller, but growing, body of research concerning the ecology of greenways and urban areas, and it does so through the lens of landscape planning. Findings on the Cameron Run watershed are reported, and biodiversity conservation in the watershed is discussed in the context of greenway efforts at local and metropolitan scales. 相似文献

Understanding opportunities and challenges for collaborative greenway planning in New England 总被引:2,自引:0,他引:2
Protection of natural, cultural, and recreational resources requires a regional approach to greenway planning that transcends political boundaries. Previous research on greenway planning has shown there are four main challenges in multi-jurisdictional greenway implementation: inter-governmental coordination, the lack of regional governance, funding, and public perceptions about greenways. The focus of this study was to understand successful strategies for collaborative greenway planning in the fragmented political landscape of New England (USA). To understand these issues, in-depth interviews were conducted with key greenway planners in New England from federal and state agencies and non-governmental organizations. The results of the study revealed four key strategies that are essential to multi-jurisdictional greenway planning in New England: partnerships, clearly defined goals, public involvement, and regional coordination. This study provides lessons for greenway planners who are implementing regional greenways across state, provincial, and international boundaries. 相似文献
