新疆阿尔泰区域矿产特征与古老基底的关系探讨

新疆阿尔泰地区矿产存在着明显的东西差异，究共原因是阿尔泰处于三大板块的会聚部位．不同的基底性质有所不同。该地区前寒武系基底主要由元古代克木齐群和富蕴群岩石组成，克木齐群属中下元古代，主要分布于阿尔泰西部和南部．富蕴群属中上元古代．主要分布于阿尔泰东部、东北部。岩石学和岩石化学特征表明，克木齐群更多具有上地幔和下地壳的成分．富蕴群则具有上地壳的成分；稀土元素分配特征和铅同位素特征表明东西部矿床和各自的基底关系密切，后者的差异导致了新疆阿尔泰地区矿产特征的差异。     

CLIMATE CHANGE AND NATURAL HAZARDS IN NORTHERN CANADA: INTEGRATING INDIGENOUS PERSPECTIVES WITH GOVERNMENT POLICY

A study of the relationship between natural hazards and climate change in the international context provides the background for a discussion of the expected changes. In the context of this global discussion, this paper reviews the current perspectives of those natural hazards that are likely to be influenced by climate change, using northern Canada as a regional case study. The northern implications of the United Nations Framework Convention on Climate Change are examined, including the status of climate change action by the northern territorial governments, the evolving role of indigenous people, and the responsibility for climate change impacts. The difficulties surrounding natural hazards research in remote locations, and the approaches of indigenous people to natural hazards are then presented. The paper concludes with a suggested policy approach for climate change and natural hazards in northern Canada, underscoring the need for more comprehensive adaptive strategies to complement the current tendency to focus on the mitigation of greenhouse gases produced in this region.

开放型历史文化名城主题公园的建设

长期以来,历史文化名城的保护工作受到以商住房地产开发为主要形式、"投资者主导型"为开发模式的旧城改造浪潮的冲击.历史文化名城主题公园以保护古城风貌、延续城市历史文脉为宗旨,运用主题公园的规划设计、经营管理等方法和开发模式,以保留、修复、移植和改造古城建筑为技术手段,建设成为集名城风貌观光、史籍博览、特色商品购物、民俗文化娱乐为一体的旅游目的地,从而达到保护历史古城风貌,树立文化名城形象的目的.

Knowledge, values, uses and management of the Araucaria araucana forest by the indigenous Mapuche Pewenche people: A basis for collaborative natural resource management in southern Chile

One of the most important endemic tree species of Chile and at the same time one of the most endangered ones is Araucaria araucana (Mol.) C. Koch, the monkey‐puzzle tree. It grows in the Andes Mountains, homeland of the indigenous Mapuche Pewenche people who depend on this tree. This paper is based on field research that investigated the ecological knowledge, uses and management of the Araucaria araucana forest by indigenous Mapuche Pewenche people based on the socio‐cultural, spiritual and ecological relationships they have with the Araucaria forest, to find out how indigenous people and their knowledge could contribute to sustainable Araucaria forest management. A Mapuche Pewenche community located in the IX region of Chile contributed to this study. Based on the analyses this paper illustrates the nature of indigenous ecological knowledge of Araucaria araucana on the one hand, and its utility in native forest management on the other. The research shows that the Mapuche Pewenche hold ecological knowledge and conduct practices to manage their Araucaria forest in a balanced way. They conserve and use forest biodiversity at one and the same time. This paper provides recommendations for sustainable Araucaria forest management and conservation strategies ex‐situ and in‐situ incorporating indigenous knowledge and scientific knowledge and for promoting a collaborative natural resources management.     

Effects of payments for ecosystem services on wildlife habitat recovery

Conflicts between local people's livelihoods and conservation have led to many unsuccessful conservation efforts and have stimulated debates on policies that might simultaneously promote sustainable management of protected areas and improve the living conditions of local people. Many government‐sponsored payments‐for‐ecosystem‐services (PES) schemes have been implemented around the world. However, few empirical assessments of their effectiveness have been conducted, and even fewer assessments have directly measured their effects on ecosystem services. We conducted an empirical and spatially explicit assessment of the conservation effectiveness of one of the world's largest PES programs through the use of a long‐term empirical data set, a satellite‐based habitat model, and spatial autoregressive analyses on direct measures of change in an ecosystem service (i.e., the provision of wildlife species habitat). Giant panda (Ailuropoda melanoleuca) habitat improved in Wolong Nature Reserve of China after the implementation of the Natural Forest Conservation Program. The improvement was more pronounced in areas monitored by local residents than those monitored by the local government, but only when a higher payment was provided. Our results suggest that the effectiveness of a PES program depends on who receives the payment and on whether the payment provides sufficient incentives. As engagement of local residents has not been incorporated in many conservation strategies elsewhere in China or around the world, our results also suggest that using an incentive‐based strategy as a complement to command‐and‐control, community‐ and norm‐based strategies may help achieve greater conservation effectiveness and provide a potential solution for the park versus people conflict.     

环境污染对戒烟人群的心理警示作用建模分析研究

环境污染过程中,由于对污染源的轻视最终造成极大的污染后果,分析污染生成过程对戒烟人群的心理会产生一定的警示作用,因此,针对环境污染过程的警示作用提出戒烟人群的心理警示作用模型.建模过程中对四项衡量指标进行计算分析,经过模型修订最终完成警示模型的构建.使用构建的模型对戒烟人群进行心理警示评估.通过试验分析可知,建立的警示模型在通常状态下能够对戒烟人群达到警示督促作用.
