河南省自然旅游资源区划研究

地表自然条件的地域差异构成了千变万化的景象和环境,使得自然旅游资源也呈现区域差异性。以综合分析、主导因素、相对一致性、完整性和梯度分级为原则,以地貌形态为主导因素,以自然旅游资源类型、数量和品质为指标,将河南省自然旅游资源划分为中部资源独特区、北部资源差异区、西部山地资源密集区、南部山水资源丰富区、东部平原资源贫乏区5个大区和12个亚区,并对各区自然旅游资源的特征、开发利用现状进行评述。     

树木地貌学在地质灾害研究中的应用

地质灾害对人类及环境造成的影响巨大,了解灾害发生的规律及影响机制对防灾减灾有重大意义。树木分布广泛,不会迁移,一般情况下每年形成一圈记录当年环境状况的年轮,利用树木年轮信息能够分析环境因子的时空变化。树木地貌学已普遍应用于地震、泥石流、滑坡等地质灾害研究,通常以重建灾害发生的时间、影响范围、运动过程等为基础,评价地质灾害对森林结构组成、地貌变化的影响,分析灾害在时间及空间上的变化过程,结合气象及水文数据,能够探讨诱发灾害的可能原因,进而推测在全球变化大背景下的发展趋势。为此,探讨了利用树木年轮重建地质灾害的理论基础,总结了主要研究成果并分析了当前研究的不足,指出以后的研究方向。     

气候变化情景下中国自然生态系统脆弱性研究——一个基于生态地理区域的研究(英文)

Assessment of vulnerability for natural ecosystem to climate change is a hot topic in climate change and ecology, and will support adapting and mitigating climate change. In this study, LPJ model modified according to features of China's natural ecosystems was employed to simulate ecosystem dynamics under A2, B2 and A1B scenarios. Vulnerability of natural ecosystem to climate change was assessed according to the vulnerability assessment model. Based on eco-geographical regions, vulnerability of natural ecosystem to climate change was analyzed. Results suggest that vulnerability for China's natural ecosystems would strengthen in the east and weaken in the west, but the pattern of ecosystem vulnerability would not be altered by climate change, which rises from southeast to northeast gradually. Increase in ecosystem vulnerable degree would mainly concentrate in temperate humid/sub-humid region and warm temperate humid/sub-humid region. Decrease in ecosystem vulnerable degree may emerge in northwestern arid region and Qinghai-Tibet Plateau region. In the near-term scale, natural ecosystem in China would be slightly affected by climate change. However, in mid-term and long-term scales, there would be severely adverse effect, particularly in the east with better water and thermal condition.

A Study of Resource Curse Effect of Chinese Provinces Based on Human Developing Index

Traditional opinion considers that natural resources play an important positive role in economic development, while resource curse theory holds that natural resources usually obstruct economic increase. This debate needs further exploration. In most of empirical studies on resource curse theory, the economic development of an area is mainly evaluated by the Gross Domestic Product （GDP）, however, the social and cultural contents of economic development are seldom considered. Thus, the Human Developing Index （HDI） was chosen to describe the comprehensive developing situation of an area in our study. Based on the panel data from the year of 2000 to 2011, the relationship between Human Developing Index and resource exploitation degree （RED） of 30 provinces in China （Tibet, Tai- wan, Hong Kong and Macao were not included because of the restriction of data acquisition） was investigated by correlation coefficient analysis and regression analysis. We found that resource curse did exist over the entire country and its effect on 30 provinces were not exactly the same. According to the effects of resource curse, these provinces could be classified into four types： no resource curse prov- inces, slight resource curse provinces, severe resource curse provinces, and extreme resource curse provinces. Testing from two short time periods 2000-2005, and 2006-2011, the resource curse effect was not prominent. However, testing from the entire period of 2000-2011, the effect was obvious among each province.     

Vulnerability of natural ecosystem in China under regional climate scenarios：An analysis based on eco-geographical regions

Does the Social Capital in Networks of “Fish and Fire” Scientists and Managers Suggest Learning?

Patterns of social interaction influence how knowledge is generated, communicated, and applied. Theories of social capital and organizational learning suggest that interactions within disciplinary or functional groups foster communication of knowledge, whereas interactions across groups foster generation of new knowledge. We used social network analysis to examine patterns of social interaction reported in survey data from scientists and managers who work on fish and fire issues. We found that few fish and fire scientists and managers interact with one another, suggesting low bridging social capital and thus, limited opportunity for generation of new knowledge. We also found that although interaction occurs among scientists—suggesting modest bonding social capital—few managers interact with other managers, indicating limited opportunity for communication of scientific knowledge for the purposes of application. We discuss constraints and opportunities for organizational learning evident in these patterns of social interaction among fish and fire scientists and managers.     

Research Approaches for Understanding,Enhancing, and Monitoring Community Resilience

The growing interest in the understanding of community resilience suggests a need for improving research approaches. This article reviews methods used to date, and suggests opportunities for expanding the range and efficacy of approaches used to understand, improve, and monitor the coupled social and ecological aspects of community resilience. We explore three potential foci: research approaches that enhance understanding of community resilience; those that help to improve community resilience through the research process; and the further development of methods to guide monitoring. Most studies have relied on mixed and multistaged methods, including in-depth interviews and case studies. We comment on the wide range of approaches used, and suggest others that could be valuable. There is particular scope for greater use of cumulative studies, historical or retrospective studies, participatory methods, and systems approaches, and a need for more methods that explore the coupling of social and ecological dimensions.     

Wildfire-Migration Dynamics: Lessons from Colorado's Fourmile Canyon Fire

The number of people living in wildfire-prone wildland–urban interface (WUI) communities is on the rise. However, no prior study has investigated wildfire-induced residential relocation from WUI areas after a major fire event. To provide insight into the association between sociodemographic and sociopsychological characteristics and wildfire-related intention to move, we use data from a survey of WUI residents in Boulder and Larimer counties, Colorado. The data were collected 2 months after the devastating Fourmile Canyon fire destroyed 169 homes and burned more than 6,000 acres of public and private land. Although this study is working with a small migrant sample, logistic regression models demonstrate that survey respondents intending to move in relation to wildfire incidence do not differ sociodemographically from their nonmigrant counterparts. They do, however, show significantly higher levels of risk perception. Investigating destination choices shows a preference for short-distance moves.     

Improving National Park Service and Nonprofit Partnerships—Lessons from the National Trail System

Federal land management agencies are increasingly relying on collaborative partnerships for managing national trails, heritage areas, scenic rivers, and recreation areas. For agencies such as the National Park Service, these joint approaches are significantly different from traditional management approaches. This article uses a case study of the Juan Bautista De Anza National Historic Trail to identify partnership lessons for this case and other protected areas that rely on public–private partnerships. The research highlights partnership issues with nonprofit capacity and mission alignment, project momentum, and leadership dilemmas. We suggest that agencies such as the National Park Service need to assess the mission and capacity of community and nonprofit groups to determine their partnership approach. This is a significant shift, from agencies simply needing to find organizations willing to partner on collaborative management efforts, to a role in assessing, forming, and developing nonprofit partners.
