【摘要】 目前面对城市快速发展所带来的种种问题,美国的greenway已成为解决一系列城市问题的重要手段,同时较为成熟的理念与经验被其他各国所吸收,并付诸实践。我国珠三角在探索解决城市问题的途径上也开始引入greenway的建设模式,并将其定义成“绿道”。虽然“绿道”建设在全国范围内已经呈现出蓬勃兴起之势,但“绿道”概念的定义以及其建设的方式与方向等诸多问题,还表现得较为模糊与盲目。通过对美国greenway从最初的“公园路”发展到现阶段“相互连接的土地保护网路”的发展过程的回顾与梳理,得出现阶段美国的greenway其网络连接性和多功能性正得以逐步强化,并彰显其在生态保护、遗产保护、游憩体验等方面的功能与内涵。并通过对现阶段美国greenway定义、结构、构成方式、功能、分类及案例的分析,进一步明确了美国greenway的内涵。在回顾中国绿道发展过程,并对珠三角绿道规划及建设实施情况进行典型性分析的基础上,进行与美国greenway在各发展阶段、现阶段建设出发点、相关理念和具体实施等方面进行横向比较,初步得出现阶段中国“绿道”的发展,仅仅停留在基于“绿”与“道”的组合理解基础上所形成的单一建构模式,这与美国greenway发展的初级阶段特征极为一致,更类似于美国面向户外游憩所建设的游步道系统,与greenway所构建的“土地保护网络”之间,无论是深度,还是广度,以及维度等方面还存在一定差距。两者目标与差距的双重明确,不仅可以为中国绿道规划树立正确的思维与观念,同时为广泛的建设提供了以资借鉴的方法与途径。更多还原

【Abstract】 At present, the rapid development of urban has brought a series of problems. In face of this situation, American greenway has become an important solution. Meanwhile, relatively mature ideas and experience are adopted by other countries and are put into practice then. The construction mode of greenway has also been introduced into the solution to the urban problems in Pearl River Delta of China, which is defined as "greenway". However, although the construction of "greenway" throughout the country is on an uptrend, the definition of "greenway", and the manner and direction of construction are still very vague and blind. Through the review and reorganization of the conception and mode of American greenway which starts from the initial "park way" and develops to the current "inter-connected land protection network", it proves that it is the development of the features such as the network connectivity and multifunction integration of American greenway that make it as a comprehensive solution in the aspects of ecological protection, heritage conservation, recreation experience.Then through the analysis of the present American greenway on the aspect of definition, structure, structure mode, function, classification and case to further clarify the connotation of American greenway.Based on the review of the development of Chinese greenway and the typicality analysis of greenway planning and construction implementation in the Pearl River Delta of China, this paper horizontally compares them with the development stage, starting point at present、related ideas and specific implementation of the current American greenway. It proves that the current development of Chinese greenway only stay in the single construction mode which is based on the simple combination of "green" and "road". Chinese greenway at present is almost the same as the early stage American greenway which is similar to the footpath system for outdoor recreation in the U.S. No matter in the depth, breadth or in the dimension, Chinese greenway still lags behind from the "land protection network" constructed by American greenway. The double confirmation of the target and difference in Chinese greenway and American greenway will not only set up the correct thinking and conception for the greenway planning in China, but also provide advisable means for extensive construction.更多还原
