The Geographer and the Fengshui Practitioner: So close and yet so far apart?

Fengshui deserves serious scrutiny from geographers. Fengshui has been a highly significant influence on the shaping of human environments in the Chinese cultural sphere for at least 4000 years. Efforts to eliminate it in the twentieth century, by Chinese governments intent on modernisation, have failed. Advice on fengshui is still eagerly sought today by families and businesses in Chinese communities, whether on the mainland, offshore or overseas. The first part of this paper briefly introduces fengshui . The second part applies Lefebvre's three modalities of space to the time-space manipulations and outcomes of the operation of fengshui . The third part explores what fengshui offers a postmodern world, concentrating on (a) the nature of the 'harmony' it seeks to establish between people and nature; (b) the nature of fengshui 's time-universe; and (c) the extent to which fengshui 's goals of time-space harmony offer a framework for approaching sustainable development.

Relationship of Stakeholders in Protected Areas and Tourism Ecological Compensation: A Case Study of Sanya Coral Reef National Nature Reserve in China

The first step to defining the rights, responsibilities and interests of stakeholders and constructing a compensation mechanism is to identify the stakeholders and clarify their mutual relationships. Nature reserves are complex ecosystems involving nature, the economy and society. There exists a conflict between the public welfare benefits of ecological conservation and the private gains to be realized from social and economic development. There also exist in a nature reserve complex relationships among stakeholders, involving the utilization of ecological resources, ecological conservation and ecological-economic interests. The introduction of tourism brings substantial changes to the existing stakeholder benefit structure in a nature reserve. The implementation of tourism ecological compensation (tourism payment for ecological service) is a process for redefining the distribution of rights, responsibilities and profits among stakeholders and it is also an essential way to balance the interests of the stakeholders. This paper uses a case study of Sanya Coral Reef National Nature Reserve in China to examine the characteristics of stakeholders and analyze their interests. According to the method for defining basic attributes proposed by Mitchel and other scholars, in cases of tourism ecological compensation, stakeholders can be classified as definitive stakeholders, expectant stakeholders and latent stakeholders. This paper applies these classifications and then analyzes the relationships between the rights and responsibilities of these stakeholders and how these change after the implementation of compensation. Additionally, based on the impact compensation has on different stakeholders, changes in the relationships can be analyzed and the structure of the stakeholders can be modelled. This case study of the Sanya Coral Reef National Nature Reserve illustrates the operationalization of a new mechanism for tourism ecological compensation. The paper illustrates a method for coordinating the relationships among the stakeholders involved with this national-level nature reserve.     

Freeze-thaw processes of active-layer soils in the Nanweng'he River National Natural Reserve in the Da Xing'anling Mountains,northern Northeast China

The active-layer soils overlying the permafrost are the most thermodynamically active zone of rock or soil and play important roles in the earth-atmosphere energy system. The processes of thawing and freezing and their associated complex hydrothermal coupling can significantly affect variation in mean annual temperatures and the formation of ground ice in permafrost regions. Using soil-temperature and-moisture data obtained from the active layer between September 2011 and October 2014 in the permafrost region of the Nanweng'he River in the Da Xing'anling Mountains, the freeze-thaw characteristics of the permafrost were studied. Based on analysis of ground-temperature variation and hydrothermal transport characteristics, the thawing and freezing processes of the active layer were divided into three stages:(1) autumn-winter freezing,(2) winter freeze-up, and(3) spring-summer thawing. Variations in the soil temperature and moisture were analyzed during each stage of the freeze-thaw process, and the effects of the soil moisture and ground vegetation on the freeze-thaw are discussed in this paper. The study's results show that thawing in the active layer was unidirectional, while the ground freezing was bidirectional(upward from the bottom of the active layer and downward from the ground surface).During the annual freeze-thaw cycle, the migration of soil moisture had different characteristics at different stages. In general, during a freezing-thawing cycle, the soil-water molecules migrate downward, i.e., soil moisture transports from the entire active layer to the upper limit of the permafrost. In the meantime, freeze-thaw in the active layer can be significantly affected by the soil-moisture content and vegetation.

会泽黑颈鹤自然保护区管理系统的设计与实现

为了实时掌握保护区珍稀动物的分布、生长情况和数量信息,该文以会泽黑颈鹤国家级自然保护区为研究对象,基于移动GIS和WebGIS技术构建会泽自然保护区信息管理系统。该系统以高清遥感影像为数据支持,将ArcGIS Server地图缓存技术融入其中,通过移动GIS进行自然保护区巡护信息采集并上传到后台服务器,采用WebGIS技术在网络客户端实时对后台服务器数据进行下载更新,从而实现移动端和网络端的信息同步。应用效果表明这种移动化、网络化的数据采集和管理模式,使自然保护区保护黑颈鹤及其越冬地的湿地生态环境工作更加科学、合理。     

Policy Drivers of U.S. Wetland Conversion Rates, 1955–2009

While conversion of wetlands to nonagricultural purposes has persisted, the five U.S. national wetland inventory reports spanning 1955–2009 show a large decline in the rate of conversion of wetlands for agriculture, especially from the mid-1970s to the mid-1990s. Through regression and path analysis, this study identifies primary policy and economic drivers of this decline in wetland conversions. The Clean Water Act §404 is strongly and negatively related to conversion rates. Crop prices affect wetland conversions both directly, by influencing returns to investments for conversion, and indirectly, by influencing Conservation and Wetland Reserve Program enrollments as well as the regulatory impact of Swampbuster. Along with the proportion of wetlands remaining, these factors explain 90–94% of the annual variation in total wetland conversions, agricultural conversions, and conversion of forested and emergent wetlands.     

海南省麒麟菜自然保护区的资源分布、存在问题与保护对策
