都市新景观 纽约高线公园

为了建设可持续发展的宜居城市,中国的城市管理者需要更加慎重地思考我们今天的城市问题,而西方发达国家一些成功的城市建设经验非常值得国内同行的参考和借鉴。通过对纽约市近年来最重要的城市更新项目——高线公园的研究：分析公园的历史、设计策略和景观施工,总结该公园的开发模式,以此来激发国内城市管理者和风景园林师对过去城市建设工作...     

Well-MADE New York City Apartments

Two New York City apartments redesigned by the Brooklyn-based practice MADE demonstrate how an architect's ability to manufacture components and manage construction can provide an unusual quality of consistency and detail. Jayne Merkel explains how the apartments, which both owners purchased for the views, have been transformed in very different ways with a rare sensitivity to the clients' needs and desires.

纽约的全球城市发展战略与规划

作为典型和领先的全球城市,纽约在全球城市发展方面的战略和规划具有一定借鉴意义。本文分析了纽约在跨国公司总部、金融业、生产性服务业、科技创新等七个全球城市发展重要维度的表现和趋势,剖析全市层面综合规划、专项规划和研究、重要地区规划和开发项目在这些维度的战略和规划应对,进而提出纽约全球城市发展战略和规划的特点和可借鉴之处。     

纽约的韧性社区规划实践及若干讨论

随着城市化和全球化进程的深入,世界大城市均进入风险高发状态,风险的复杂性、不确定性和扩散性与日俱增,韧性系统建设成为抵御风险的重要战略.特大城市因高聚集性、高流动性和全球依赖性而面临着更为复杂的风险挑战,社区作为最基础的城市治理单元,在韧性建设框架中尤为重要.本文梳理了韧性社区规划的相关概念与内容,选取参与主体、管理机制、规划工具和整体性社区方法等要素作为纽约韧性社区规划的分析框架,重点介绍并评议了197-a参与式社区规划、社区应急响应网络、滨水社区规划和整体社区调查方法的具体实践.之后笔者从政策工具、决策机制、实施路径等方面讨论了纽约实践对国内特大城市韧性社区规划的启示.     

纽约市桥梁生命周期性能的评估

对桥梁现况及使用寿命的评估在我国还是一个新的课题 ,随着城市桥梁的快速增多 ,此方面的研究与投资日趋重要。美国的相关研究处于领先的地位 ,清华大学与美国纽约市交通桥梁局将于 2 0 0 1年 9月在北京联合举行相关的讲座。本刊为配合此次活动并引入国外对相关课题研究的大致情况 ,特在本期中刊发美国B YANEV和陈晓明博士的相关文章 ,希望为我国开展桥梁评估的工作起到抛砖引玉的作用     

Gentrification and Displacement New York City in the 1990s

Gentrification has been viewed by some as a solution to many of the problems facing older central cities. At the same time, many are wary of the potential for gentrification to displace disadvantaged residents. To date, however, surprisingly little reliable evidence has been produced about the magnitude of this problem that could guide planners, policymakers, or community-based organizations. The study described in this article attempts to fill this void by examining residential mobility among disadvantaged households in New York City during the 1990s. We found that rather than rapid displacement, gentrification was associated with slower residential turnover among these households. In New York City, during the 1990s at least, normal succession appears to be responsible for changes in gentrifying neighborhoods. The article concludes with a discussion of the implications of these findings for planning.     

New York City (Steady) State

What would happen if New York became a self-sufficient city state, entirely self-reliant in terms of food, waste, energy, movement, manufacture, building, water and clean air? Michael Sorkin provides a masterplan for the metropolis with an ecological footprint that coincides with its political boundaries. Controversially, he explores the possibilities of urban autonomy and what the necessary steps might be in transforming a city's form.     

New York City Street Trees by Species

New York City's urban forest provides numerous environmental and social benefits. Street trees compose roughly one quarter of its canopy. This map shows the distribution and biodiversity of the city's street trees based on the most recent tree census. The map is more than a way for identifying the placement of trees: it provides a record of planting history and an important tool for planning.     

Sources of pharmaceutical pollution in the New York City Watershed

An investigation was carried out in the New York City Watershed for the presence of selected pharmaceuticals. In four seasonal sampling events between August 2003 and May 2004, surface water was collected from eight reservoir keypoints and effluent was collected from four wastewater treatment plants. We evaluated the following twelve compounds: amoxicillin, atenolol, caffeine, carbamazepine, cephalexin, estrone, 17alpha-ethinylestradiol, 17beta-estradiol, ibuprofen, sulfamethoxazole, trimethoprim, and valproic acid. In the treated effluents, carbamazepine was detected most frequently (100%; concentration range: 22-551 ng/L), followed by atenolol (94%; ND - 14,200 ng/L), trimethoprim (83%; ND - 37,000 ng/L), ibuprofen (61%; ND - 14,600 ng/L), and caffeine (49%; ND - 37,200 ng/L), while estrone was detected once (56 ng/L). In the reservoir keypoint samples, only ibuprofen (2.5%; ND - 932 ng/L) and caffeine (2.9%; ND - 177 ng/L) were detected. The other analytes were not detected in any sample. It is expected that investigation of other wastewater treatment plants in the New York City Watershed would show that their effluents are also a potential source of pharmaceuticals, but that these pharmaceuticals are unlikely to be detected in the Watershed's surface waters.
