城市滨水绿道发展研究综述

滨水绿道作为绿道中重要的类型之一,是城市中最为生态的开敞空间,有着生态、休闲、游憩、经济、社会、文化等多方面的功能,本文梳理了滨水绿道的概念及内涵,通过对国内外滨水绿道研究及实践的探讨,分析了目前我国滨水绿道研究的不足和未来发展方向,期望对我国城市滨水绿道研究提供经验借鉴。     

找寻记忆的归宿——台儿庄马兰屯镇京杭运河绿道景观改造设计研究

城市的快速发展让人们逐渐模糊了对历史文化及自然环境的记忆,方案旨在改善台儿庄马兰屯镇京杭运河沿岸的自然环境质量,营造一个良好的自然景观和历史文化景观体验地,使运河景观改造设计具有本土性和地域性。在方案设计中,充分利用场地现有的景观资源、生态资源、人文资源:提出与台儿庄古城氛围相融洽,与传统的地域文化相结合,又体现时代精神的设计思路:整个方案表达出绿色生态休闲的主题,侧重运河文化与自然景观规划的系统性。

重庆主城区滨江绿地生境质量研究 — —以夏季鸟类为指示类群

河流廊道对城市化区域生物多样性 保护至关重要。为探明重庆主城区滨江绿地 生境质量,选择以夏季鸟类为指示类群,通 过样线法对滨江区域20个绿地斑块进行了 调查,并开展了群落相似性分析、聚类分析、 物种多样性和指示种计算等相关分析。结果 表明,研究区域雀形目鸟类占绝对优势,比例 为78.12%,留鸟居多占71.88%;样地间鸟类 群落结构相似性普遍较低,中等不相似和极 不相似群落各占53.68%和23.16%;鸟类群落可聚为3类,分别对应受轻度、中度和重度干扰的3类生境;各干扰程度生境中鸟类多样性指数均 较低,且在受不同干扰程度影响的生境间无显著差异;位于城乡边缘地带的重度干扰型生境中 鸟类多样性指数均高于轻度干扰型;轻度干扰型生境指示种为白颊噪鹛和白头鹎,重度干扰型 为麻雀。根据以上结果,重庆主城区滨江绿地鸟类生境普遍受到城市化影响。建议在未来的城 市滨江空间建设过程中,应注重绿地生境修复和营造,并同时优化城乡边缘地带土地利用管理, 保育优质绿地生境。

Mercury in the environment and riverside population in the Madeira River Basin, Amazon, Brazil

This work presents quality control results on the mercury concentrations in different environmental (river sediments, forest soils, river suspended matter and fish) and human samples from the lower Madeira River, Amazon sampled between 2001 and 2003, about 15-20 years after the nearly cessation of gold mining activities in the region, which reached its peak in the late 1980s. The study aimed to compare mercury concentrations in these environmental samples with those reported by other authors during the gold rush of the Madeira River Basin. Today, in the Madeira River the releases of mercury register a sudden reduction due the gold price fall in the international trade. However, about 100 t of Hg were released to the atmosphere and to aquatic systems in the region during the gold rush. The present survey shows that notwithstanding the reduction of Hg emissions to the Madeira River Basin from gold mining proper, concentrations in fish and humans are similar to those measured during the gold rush. Reduction in Hg concentrations is restricted to areas close to old point sources and only for abiotic compartments (air and sediments). Remobilization of Hg from bottom sediments plus re-emission from soils due to land use changes are probably responsible for keeping high Hg concentrations in biological samples.     

The history and future directions of greenways in Japanese New Towns

A number of societal changes such as an ageing population and a lack of economic prosperity mean that Japanese greenway planners will be faced with a number of new challenges in the coming decades. These societal changes will be particularly dramatic in the Japanese New Towns, which were constructed in the late 1950s. Some of these New Towns marked a departure for Japanese planning by including a network of greenways, which were planned to provide pleasant corridors for pedestrians and bikers. Around 30 years have passed since these areas were developed; today the greenways in these New Towns have become corridors with dense and rich greenery. Such matured greenways, which were supposed to provide an amenity for local residents, have increasingly come to be regarded as a cause of fear of crime. To try and mitigate this, trees and shrubs along the greenways are now closely trimmed or even removed.However, such mature vegetation along the greenways may be regarded as a feature that maintains the history of the town. Such vegetation is also expected to provide ecological corridors that accommodate wildlife species which were abundant in the rural areas surrounding these New Towns. Within the context of proposing an optimum management scheme for Japanese greenways, the following study aims to explain and discuss how the fear of crime on greenways can be prevented whilst maintaining their ecological and historical functions.

绿道作为国家与地方战略 从国家生态基础设施、京杭大运河国家生态与遗产廊道到连接城乡的生态网络

绿道作为维护生态过程和生态系统完整性,发挥生态系统服务价值的土地网络系统,可以成为国家和地方战略,提供整合自然保护、文化与自然遗产保护、乡土遗产保护和旅游与休闲产业发展机会。以北京大学景观设计学研究院1998年以来完成的研究成果为例,阐述建立国家绿道系统——国家生态基础设施、京杭大运河国家生态与遗产廊道的构想,以中山市、杭州市、合肥市和北京市为例阐述连接城乡的绿道网络的规划与实施途径。
