从三峡地区与东部平原的对比看考古学文化中的环境因素

三峡地区与东部平原的不同地理环境,导致了峡区和平原地区的考古学文化的差异。古代人类对不同地理环境适应的结果,是反映在考古学文化中的环境因素。     

古代江南地区圩田开发及其对生态环境的影响

江南地区的圩田大致滥觞于三国之际,迅速发展于两宋,全盛于明清,是我国江南人民在长期治田治水实践中创造的农田开发的一种独特形式。文章以大量历史文献资料为基础,全面考察了江南地区圩田开发的历程与特点,研究了江南圩田兴盛的历史因素和自然条件,并简要分析了圩田的作用。在此基础上,具体探讨了圩田开发对生态环境所造成的影响,认为因过渡围垦破坏了江南地区原有的湖泊河流水文环境,造成“水不得停蓄,旱不得流注”的严重局面,这便给圩田大大增加了防患水灾的压力;历代地方政府在圩田管理方面也是各自为政,各地圩田缺乏相互间的协作,使因破圩而形成的局部水灾年年有之;大量构筑圩田,使湖泊面积大为缩小,影响其调节水量的功能,破坏了本地区的生态条件,致使灾害频频发生。此外,围湖特别是废湖以后,使众多的水生资源也遭到了严重破坏。     

赤水“桥上桥”与生态环境变迁

本文考证了渭南、华县之间的赤水河“桥上桥”的建造年代及形成原因。通过对有关历史资料深入研究,确证下桥始建于清初(1667年),上桥则建于清朝中叶(1832年)。赤水河中上游的过度垦殖和植被破坏带来的生态环境恶化造成了下游河床泥沙淤积,形成了地面悬河,原赤水桥为泥沙淹塞,失去功能,故不得不在桥上建桥。桥上桥的形成是当地生态环境变化的结果和标志。

中日环境合作的战略互惠性

经过2006年10月以来中日两国领导人的数度互访,努力构筑“基于共同战略利益的互惠关系”（简称“战略互惠关系”）成为新世纪双边关系的基本框架。环境合作是双方首脑共同确认的“战略互惠关系”的重要内涵,更被各界冀望于成为提升和深化双边关系的突破口。从环境问题的全球性发展、中日双边关系的转型以及环境合作对于今后中日双边关系的重要性等角度来看,中日环境合作所具备的战略互惠性决定了这一领域必然成为未来较长一段时期两国关系的突出“亮点”。     

从《七佛说法图》谈壁画的保护研究

故宫博物院绘画馆中陈列的《七佛说法图》堪称元代寺观壁画中的珍品,但由于受各种因素的影响,已经出现了不同程度的损坏,迫切需要采取有效的措施予以保护。本文通过对壁画现状的调查和监测,总结出导致壁画受损的主要因素,从而有针对性地提出了保护方案。同时,结合数字化技术对壁画保护的前景进行了展望。     

可持续发展思想史述评

可持续发展是人类与自然关系认知史上的一次重大转折和飞跃,是人类痛定思痛后的明智抉择。人类对于人与自然关系的认知,经历了人和自然的原始统一、农业文明时代朴素的“天人合一”、工业文明时代人与自然的冲突和生态文明时代人与自然的和谐统一等几个主要阶段。可持续发展是人类的理想与追求,也是人类生存、延续和发展的必由之路。     

自然环境变迁与十六国政权割据局面的出现

中国古代历史发展的自然环境及自然环境变迁对历史进程的影响,起一个具有重大理论和现实意义的问题。东汉末年以来自然环境变迁是西晋灭亡和十六国割据局面形成的重要原因。由于全球性寒冷干燥期的出现,我国北方沙漠面积不断扩展,各游牧民族原有的生存环境不断恶化,于是纷纷南迁,起着西晋统治集团内乱之际,夺取了政权。     

Fighting over the Forests: Environmental Conflict and Decision‐making Capacity in Forest Planning Processes

This paper tells a story of environmental conflict and the attempted political resolution of issues of planning for native forests in Western Australia. It refers to the Western Australian Regional Forest Agreement and Draft Forest Management Plan processes to demonstrate how a range of actors utilise vari‐ous discourses and network relations in attempts to influence governmental decision‐making capacity. Adapting elements of a model of capacity‐building for environmental decision‐making, the paper indicates how traditional exclusionary decision networks serve to inhibit decision capacity, whilst more inclusive processes may be more likely to cope with challenges of reconciling multiple values and decision‐making for managing the forests in the interests of society as a whole.     

Prospects for the Rural‐Urban Fringe in Australia: Observations from a Brief History of the Landscapes around Sydney and Adelaide

Despite being a major site of recent population growth and, arguably, a key arena for sustainability concerns, the rural‐urban fringe has received relatively little attention in the literature concerning Australian cities and urban policy. To address this shortcoming the authors review post‐World War II efforts to plan the rural‐urban fringes of Sydney and Adelaide and find a number of issues for contemporary policy‐makers. First, the fringe is becoming increasingly complex due to multi‐faceted demographic change, a broadening economic base and demands for better environmental management, all within the context of an evolving understanding of sustainability. Second, water resource management, partly under the auspices of integrated natural resource management, is assuming a much higher priority than in early fringe planning endeavours, which emphasised urban containment, agricultural land protection and landscape conservation. Third, and partly as a consequence of this shift of priorities, there is also evidence of changes to the nature and focus of policy tools used in the fringe, with land management concerns now cutting across traditional land use planning. Finally, and fundamentally, these observations raise questions about how future governance of the fringe should be organised. Together these four themes pose an enthralling series of challenges for policy‐makers for which much more research and discussion are needed.
