4.3. Greenways and greenspaces for the United
States
The impetus for this plan for the United States
has three sources. First, the New England Greenway
Vision Plan of 1999 paved the road for a national
plan. The team expressed an interest for a national
greenway system to Bill Welsh, the editor of LAND
in 1999 (see Welsh, 1999, p. 4). Second, the visionary
National Plan of landscape architect Warren Manning
from the 1920s was recently reprinted and described
by Lynn E. Miller (November 1999, p. 58). Third,
as part of a greenway seminar during the spring of
2000, the author’s interest was to review the remarkable
efforts of the US Federal government, whose
agencies have planned and managed one third of the
nation’s landscapes during the last century. Their
federal efforts provide the framework for a more
comprehensive national plan for greenspaces and
greenways.
The challenge was to undertake this effort without
any dedicated funding. The Department of Landscape
Architecture and Regional Planning, however,
provided the team of graduate students with computer
facilities, space and office supplies.1
4.3.1. An overview of the United States
The continental United States is the focus of
this study. The states of Alaska and Hawaii are
not included. The area size of the lower 48 states
is 7,825,155 km2. The Federal Land area is around
2,600,000 km2 in the lower 48 states (National
Geographic, 1992, p. 20). The majority of the public
land, however, is located in the west in the mountainous
regions of Rocky and Cascade Ranges. These
mountain ranges are among the most spectacular
mountains of the world. The United States is also
blessed with thousands of miles of shoreline along
the East and West coasts as well as the Gulf of Mexico
and Great Lakes. The river system, the backbone
of greenways are also very large and extensive in the
United States with over a hundred major rivers, that
are nationally significant, and constitute that “giant
circulation system” flagged by the President’s Commission
Reports for a greenway network (1987). Finally,
the United States has over 256,000 km of abandoned
railroads. To date over 19,000 km have been
converted to trails. The remaining abandoned railroad
tracks have the potential for trail conversion which
would create a huge network of rail trails across the
United States. All these resources provide the United
States with great opportunity to create an extensive
and high quality national network of greenways and
greenspaces.

4.3 美国的绿色道路和绿色空间
The impetus for this plan for the United States
has three sources. First, the New England Greenway
Vision Plan of 1999 paved the road for a national
plan. 就美国来说，这一计划的推动力有三个来源。第一个是1999年的，为国家计划铺设道路的新英格兰绿道计划。The team expressed an interest for a national
greenway system to Bill Welsh, the editor of LAND
in 1999 (see Welsh, 1999, p. 4). 研究小组在1999年向Bill Welsh（LAND的编辑）表达了对国家绿道体系的兴趣（参见Welsh，1999，第4页）。Second, the visionary
National Plan of landscape architect Warren Manning from the 1920s was recently reprinted and described by Lynn E. Miller (November 1999, p. 58). 其次是1920年景观设计师Warren Manning写的想象的全国计划最近被Lynn E. Miller ( 1999, 11，p. 58)重新印刷和描述了。Third, as part of a greenway seminar during the spring of
2000, the author’s interest was to review the remarkable
efforts of the US Federal government, whose
agencies have planned and managed one third of the
nation’s landscapes during the last century. Their
federal efforts provide the framework for a more
comprehensive national plan for greenspaces and
greenways.
第三，作为2000年春季绿道研讨会的一部分，作者的兴趣是回顾评价美国联邦政府引人注目的努力，在上一世纪，政府的机构一直在规划和管理三分之一的国家景观。它们的联合努力为绿色空间和绿色道路更全面的国家计划提供了框架。
The challenge was to undertake this effort without
any dedicated funding. The Department of Landscape
Architecture and Regional Planning, however, provided the team of graduate students with computer facilities, space and office supplies.1
其挑战是在没有任何捐献资金的情况下进行这样的努力。不管怎样，景观设计和地区规划处为研究生小组提供了计算机设备、空间和办公室等

4.3.1 美国的综述
大陆美国是这项研究的焦点。阿拉斯加和夏威夷州不包括在内。下面48个州的面积大小为7,825,155 km2.
The Federal Land area is around 2,600,000 km2 in the lower 48 states (National
Geographic, 1992, p. 20). The majority of the public
land, however, is located in the west in the mountainous
regions of Rocky and Cascade Ranges. 联邦的土地面积在下面48个州大约为2,600,000 km2 （国家地理，1992，p.20).可是，大多数公共土地都位于落基山和喀斯喀特山脉多山地区的西部。These mountain ranges are among the most spectacular
mountains of the world. 这些山脉属于世界上最壮观的山脉。The United States is also
blessed with thousands of miles of shoreline along
the East and West coasts as well as the Gulf of Mexico
and Great Lakes. 美国也因沿东西海岸以及墨西哥湾和北美五大湖绵延数千英里的岸线而神圣化。The river system, the backbone
of greenways are also very large and extensive in the
United States with over a hundred major rivers, that
are nationally significant, and constitute that “giant
circulation system” flagged by the President’s Commission
Reports for a greenway network (1987).河流系统作为绿色道路的骨架在美国也是非常大量和广泛的，有100多条大河，它们从国家来说意义重大，而且构成了“巨大的流通体系”，这由总统委员会关于绿道网络的报告作为标志。 Finally,
the United States has over 256,000 km of abandoned
railroads. To date over 19,000 km have been
converted to trails. 最后，美国有超过256000km被遗弃的铁路。迄今，超过19000km已经转换成步道。The remaining abandoned railroad
tracks have the potential for trail conversion which
would create a huge network of rail trails across the
United States. 其余遗弃的铁路轨道有可能进行步道转换，而这会在美国产生一个巨大的铁路步道网络。All these resources provide the United
States with great opportunity to create an extensive
and high quality national network of greenways and
greenspaces. 所有这些资源都为美国提供了巨大的机会来创造广泛而优质的全国性绿色道路和绿色空间网络。

4.3。美国绿色通道和的绿地。
此为美国计划推动有三个来源。
首先，新英格兰绿色通道1999年远景计划铺平了道路的国家计划。
该小组表示，一个国家绿色通道制度，条例草案威尔士，土地在1999年编辑的利益（见威尔士，1999年，第4页）。
二，有远见的国家景观设计师沃伦曼宁计划是从20世纪20年代日前转发和林恩E的说明

联邦的努力，他们提供一个更全面的绿地和绿色通道的国家计划的框架。

4.3.1。一个美国概述
美国大陆是本研究的重点。

联邦州土地面积约二百六十〇点零万平方公里在较低的48个（国家地理，1992年，第20页）。
市民的土地不过，大部分位于在洛基和Cascade山脉以西的山区。
这些山脉中最壮观的
山中世界。
美国也得天独厚，沿东西海岸，以及墨西哥和大湖海湾海岸线数千英里。
这条河系统，绿色通道的骨干也很大，在美国广泛的超过一百主要河流，
这是国家重要的，并构成的“大流通体系”的总统委员会的报告标记的绿色通道网络（1987）。
最后，美国有超过256,000公里废弃铁路。
迄今为止超过19,000公里的被转换为路径。
其余的被遗弃的铁轨已经转换为线索将创造一个跨越美国的铁路路线的庞大网络的潜力。
所有这些资源提供了很好的机会，建立一个广泛的，高品质的绿色廊道和绿地，国家网络美国
