论绿道在中国的社会意义及发展策略

绿道在中国的发展源远流长,源予西周时的“周道”,对中国城市建设起到重要作用。近年来珠三角、长三角地区在城市绿道、省内绿道及区域绿道三个不同层面的绿道建设实践成果明娃。审视了绿道的社会意义,通过对绿道建设带来的社会价值观、生活观、幸福感和安全感转变的研究,从而提出了绿道在中国的7大发展策略：文化为基础、生态为条件、人性为根本、总体布线、多点启动、并网贯通、立法保护。     

Greenways for recreation and maintenance of landscape quality: five case studies in Portugal

The use of the concept of greenway can be identified in Portugal throughout the 20th century as a planning and design tool. Several examples, such as the ‘Improvement Plans for Lisbon’ by Ressano Garcia (1901), the continuum naturale concept [Cabral, F.C., 1980. O Continuum Naturale e a Conservação da Natureza. Conservação da Natureza. Serviço de Estudos do Ambiente, Lisbon; Andresen, T., 2001. Francisco Caldeira Cabral. Landscape Design Trust, Surrey, UK, 213 pp.], the Green Plan for Lisbon [Telles, G.R., et al., 1997. Plano Verde de Lisboa. Ed. Colibri, Lisboa, 197 pp.], deal with the subjects of implementing vegetation corridors, pedestrian networks and landscape quality. These examples establish Portuguese planning and design tradition within the international greenway movement first identified by Fabos [Fabos, J.Gy., 1991. From Park to Greenways into the 21st Century. In: Proceedings from Selected Educational Sessions, ASLA Annual Meeting, Kansas City, Missouri]. Though several projects have been developed at the planning level, there is a need to analyze the applicability of such a concept at the regional, municipal and local level. We must consider the characteristics of Portugal's cultural landscape, recognition by other professions dealing with planning and involvement by politicians. By analyzing five case studies, this paper shows the significance of the greenway as a planning and design strategy, which coincides, with the current objectives of political and planning authorities at the municipal level. It also proves that it is possible to reconcile political objectives and urban development while safeguarding landscape quality and providing new opportunities for public recreation and education. Greenway planning and design is now undoubtedly a subject of growing significance in Portugal.     

绿道在广东的兴起和创新

上海市绿道网络规划研究初探

绿道是一种具有生态、娱乐、文化、审美等多种功能,可持续发展的绿色线性开敞公共活动空间网络。结合城市发展目标,本文研究了上海市绿道的功能定位,以游憩、交通、生态等功能为主,兼具文化保护功能。绿道网络规划思路依据分区特点采用差异化规划策略,以资源布局为引导要素进行路径识别,利用“反规划”途径选择绿道线路。根据功能定位、资源布局特点以及需求特征,绿道分为区域、市级、社区三级和生态型、滨水型、保护型和交通型4类,并且结合不同的分区特点,研究各分区内绿道适宜的网络模式。     

Greenways planning in Italy: the Lambro River Valley Greenways System

The greenways movement in Europe developed differently to its counterpart in the USA, influenced by geographical, economic and cultural differences as well as differences in social and urban development.Europe has seen a discontinuous and fragmented process, diversified in the various countries. The explosion of the greenway concept in Europe is a very recent phenomenon: the European Greenways Association and the Italian Greenways Association both date back only as far as 1998. Clearly, before this date the European countries did see a degree of activity both cultural and operational, but it is equally clear that there was a lack of commonality. Specifically, greenway planning in Italy while on the one hand work has been underway on green trails for many years, on the other there is a clear lack of methodology that allows for the planning of a broader network.This paper has two objectives; firstly to define a methodology useful for greenways planning in Italy at regional level, and secondly, to demonstrate the application of this methodology to a case study.The methodology adopted derives from an approach to planning inspired principally by the work of Ian McHarg and Julius Fabos and already applied by the authors to protected areas in Italy. The methodology is structured in four phases: analysis of the landscape resources, the existing green trail and historical route networks; assessment of each element; composite assessment; and definition of the Greenways Plan.A case study for the Lambro River Valley Park is used to illustrate the methodology proposed. The park comprises the municipalities situated along the Lambro River to the north of Milan. This is densely inhabited land and features multiple human activities located within a context conserving residual elements of naturalistic, landscape and historical–cultural interest. The application of the methodology to the Lambro River Valley Park allowed the development of a greenways network incorporating the existing network of green trails: 80% of the network is, in fact, already in place. The methodology also proved to be useful in the definition of a network dedicated to non-motorized traffic capable of connecting the numerous urban centres with the many resources present in the area.     

欧洲绿道建设的理论与实践

与北美相比,欧洲的绿道建设具有很多自身的特点。总结了欧洲绿道的理念缘起、内涵以及理论与实践的发展历程,着重分析了其绿道规划的生态稳定性原则。欧洲在大型的区域性绿道生态网络与中小型城市和社区层面的综合性绿道建设方面均有相当多的探索性实践,列出了欧洲主要的大型绿道网络项目的情况,而对于中小型综合性绿道,则以伦敦东南绿链为例作了重点介绍。最后对欧洲绿道的发展趋势作了展望。     

Greenways and the making of urban form

One aspect of greenways which is exciting popular interest in the US is the durability of nineteenth-century parkways and park systems to stitch together fragmenting cities and urbanizing areas. What the Olmsteds, Cleveland, Eliot and Kessler achieved in their regional open-space plans can be the model for a new version of Howard's ‘town/country’ in which greenways/ greenbelts/greenspaces together make a comprehensive ‘green’ infrastructure.Some of the literature and the highlights of historic greenway planning and design in the US are reviewed. Their adaptation to current projects is illustrated through a series of case studies of gradually increasing scale—villages, towns, cities and regions. Such common strategies as ‘green’ streets, parks and playgrounds structuring walkable neighborhoods, intra-neighborhood parkways connecting town/city districts, and regional park systems protecting natural areas for recreation/conservation still confer similar social, economic and environmental benefits. Whether Pedestrian Pockets or Co-housing, expanding historic settlements or preserving the countryside, planning new ‘urban villages’ or neo-traditional towns, greenways can be powerful makers and shapers of urban form at both macro- and micro-scales.
