四川省实施天然林资源保护工程和退耕还林工程

1998年夏秋之际 ,长江中上游地区发生了历史上罕见的特大水灾。 8月 2 0日 ,四川省人民政府在全国率先作出重要决定 :从 9月 1日起 ,在阿坝、甘孜、凉山、攀枝花、乐山和雅安三州两地一市 ,实施天然林资源保护工程 ,禁止采伐天然林 ,关闭工程区内木材交易市场。不久又将这一禁伐令扩大到全省范围内。 1 999年 1 0月 ,为了建设长江上游生态屏障 ,四川省政府再次决定两年内在 1 2 0个县 (市 )完成 30 0万亩退耕还林试点任务。以上重要决定的制定和实施 ,对于从根本上扭转本省森林面积下降 ,遏制生态环境恶化 ,促进国民经济的发展和人民生活的改善 ,无疑具有十分重大的生态、经济和社会效益。

Paper 2: Climatic Study of the Underground Archaeological Site Coudenberg

Abstract

The excavation and valorization of subterranean archaeological remains, and eventually opening a site to the public, required a proper management and conservation strategy. This strategy was based on the evaluation of the delicate balance between the requirements for public health and safety, and the protection of the archaeological remains from future degradation. Controlling the climate can be essential for a preventive conservation strategy, which can be defined as an indirect action to increase the life expectancy of the archaeological remains, and by doing so keeping them in a preferred state of conservation to mitigate damage and/or deterioration.

Potential risks and possible interventions are outlined to avoid climatic conditions which are in conflict with the requirements for the visitors’ comfort while preventing damage phenomena to the materials.     

Global Patterns in the Exploitation of Shellfish

ABSTRACT

Shellfish are a crucial resource for past and present subsistence-level societies around the world. Despite the diversity of environments in which shellfish are exploited, an examination of the global patterns of shellfish exploitation reveal surprisingly common patterns in the opportunities allowed and constraints imposed by relying on shellfish. These commonalities, linked to the fundamental features of shellfish and their exploitation, can illuminate diverse social and ecological factors likely to influence variability in their archaeological signatures. Here we review contributions to this special issue and explore common trends in shellfish use and its archaeological consequences.     

Can a preservationist ideology halt the process of creative destruction? Evidence from Salt Spring Island,British Columbia

For more than 50 years, rural municipalities across the developed world have struggled to redefine themselves in the face of declining primary sector employment. In some places, this struggle has led to the creation of landscapes that provide heritage‐seekers with tangible commodities and intangible experiences reflecting a by‐gone past. Recent research suggests that these post‐productivist heritage‐scapes may evolve into leisure‐scapes of mass consumption, if profit or economic growth are the key motives underlying development ( Mitchell and Vanderwerf 2010 ). This article questions whether a dominant ideology of preservation can prevent this scenario. We studied Salt Spring Island, British Columbia: (i) to determine if the island displays the characteristics of a heritage‐scape, (ii) to discover if a preservationist ideology has contributed to its current state, and (iii) to ponder if this state can be maintained, in light of recent regional and provincial discourse. Our analysis reveals that the creation, and maintenance, of this heritage‐scape has been guided largely by public discourse underlain by a preservationist ideology. This prolonged state, however, may be drawing to an end. Recent provincial directives to double tourist revenues suggest that local (and regional) discourse soon may be overshadowed by the province's mandate to promote economic growth. The response of local stakeholders will ultimately dictate the Island's ability to maintain its present state as a post‐productivist heritage‐scape.     

Advanced design of Chinese traditional materials for the conservation of historic stone buildings

The conservation of historic stone buildings and sculptures is recently receiving growing attention and becoming a focus of research because of rapid changes in weather conditions (pollution, acid rain, etc.). Presently, techniques for stone conservation primarily involve the use of organic coating treatments, but their side effects have been recognized. In contrast, some traditional materials used in historic stone buildings function well for thousands of years. In this paper, we report our research on the reasons why traditional protective materials can provide an unexpected long-term protection. First, calcium carbonate was prepared according to a formula for making Chinese traditional consolidating materials, and its structure and morphology were examined by different instruments. Second, the reinforcing effectiveness of the prepared CaCO₃ powders was tested and analyzed by investigating its surface characteristics. The experimental results reveal that a biocontrolled process occurs, in which an organic template can induce the precipitation of a mineral structure, which in turn results in a great improvement in the conservation of the historic stone buildings protected by these traditional protective materials. This provides a contribution toward the development of new researches on biocontrolled processes and on some protective materials with excellent performance through biocontrolled synthesis.     

中西遗产保护比较的几点思考:一个跨文化的视角

近年来,西方国家世界遗产保护体系的实践经验对中国遗产保护产生了深远的影响。从跨文化的视角看,中国遗产保护在借鉴西方的遗产保护体制时,需要注意保护体制和管理对象的差别,也要注意东西文化的差异导致的对遗产保护中"原真性"的不同理解。因此,中国遗产保护既要重视传统历史文化和物质遗产中的精神元素,也要考虑在保护、传承和利用文化遗产的基础上充分发挥其社会功能,更要从中西方的文化差异出发,在遵守国际保护理论精神的基础上,探索出符合中国国情和文化特征的保护理论和方法。
