基于社区的地质遗迹旅游开发研究^＊——以四川八台山省级地质公园为例

地质遗迹的开发和保护是地质遗迹资源丰富地区面临的现实问题。在介绍了社区生态旅游定义以及地质公园走社区生态旅游发展道路的意义的基础上,利用国外较为成熟的社区生态旅游理念为指导,对八台山省级地质公园进行研究。提出八台山省级地质公园社区生态旅游的开发构想：①搞好地质公园内的生态旅游规划工作;②实施补偿机制;③搞好社区生态旅游示范区：走“政府引导＋社区参与＋企业经营＋科研机构介入”的开发模式,并提出相应的开发项目,为经济不发达地区地质遗迹的合理开发提供示范作用和理论依据,避免不必要的人力、物力、财力的浪费,有利于走可持续发展道路。     

Imagining Postscience: Heidegger and Development Communication

Modernization, the dominant contemporary model of development, has technoscientific rationality as its base. Alternatively, development can be understood as the ascent of individuals and communities toward their own conceptions of the good life. Such an understanding of development, it is argued, cannot be communicated under technoscientific assumptions. Instead, under the light of Heidegger's critique of technoscience and his philosophy of communication, a postscientific perspective is invoked for communicating development as good life, less violent to human communities and the environment, and less monolithic in design. Postscience evokes the multiplicity of ways in which we seek credibility for our projects in opposition to the monistic conception of truth and meaning in the technoscientific paradigm. Exploiting Heidegger's understanding of the world-disclosive power of language, development communication is understood as disclosing the genuine possibilities for the good life, concealed in a people's world, in an authentic act of engagement between the people and the communicator of development.     

Common Values and Themes for Grazed Open Spaces: “Plant Diversity” and “Watershed” as Communication Intersections for Agriculture and Conservation Groups?

ABSTRACT

Communicating about the use and management of open spaces occurs within a complex social environment replete with diverse stakeholder opinions and meta-narratives. For western US rangelands, production-based enterprises have been the traditional use but increasingly they are valued for ecosystem services such as water, recreation, biodiversity, and aesthetics which have led to additional conflict. We surveyed Wyoming-based members of six agricultural (Ag) and four environmental/conservation (Env/Con) groups to determine grazing-centric mutual exclusivity of special interests, common values, and emergent themes. We assessed 197 survey participants; 150 from Ag groups and 47 from Env/Con groups. Of 10 values assessed, “watershed” and “plant diversity” were similarly valued by both group types. These naturally dichotomous groups also agreed that communication and reliance on science are needed. Communication and conflict resolution about the use of open spaces can benefit from addressing social presuppositions and meta-narratives of broader audiences to facilitate effective dialogue and solutions.     

Sustainable Tourism Development Management of Local Cultural Landscapes

Abstract

Nowa days, ecological and cultural tourism, especially those ancient villages and towns in China, have attracted an increasing number of tourists because of their unique cultural features. However, rapid development of tourism brings economic benefits, but results in a series of problems that threaten further tourism development and protection of ancient towns, such as over-commercialization and tourism urbanization. Taking Longmen ancient town as an example, this paper presented a sustainable way of preserving and developing resources of ancient villages and towns. First, identify cultural features and the extent of ancient villages and towns, and find the approach through which a cultural landscape zoning can be applied. Second, define a cooperative function area to release the pressure on core areas and protect their authentic cultures by extending tourism space. Third, balance tourism development with traditional industries to enhance the sustainability of community economies.     

Systematic Contradiction Between Heritage Conservation and Tourism Development: Cleaning the Temple and Cemetery of Confucius and the Kong Family Mansion in Qufu

Abstract

In recent years, with the rapid development of the tourist industry, world heritage sites become more and more popular among tourists from home and abroad. Therefore, heritage tourism has become a new hotspot. However, while world heritage sites are making obvious economic benefit from tourism, they also bring various problems and contradictions, of which the most troublesome one is the contradiction between heritage conservation and tourism development. To discuss and analyze the root and the essence of the above contradiction and find a way to bring about harmony between them is an important program faced by our national heritage management practice and academic research. Based on the case of cleaning the Temple and Cemetery of Confucius and the Kong Family Mansion in Qufu, this paper analyzes the reasons why our national world cultural heritage sites bring about the above contradiction in the process of tourism development and points out that the improper system and stakeholders' benefit imbroglio are respectively the root and the essence of the contraction. Then, it also puts forward corresponding solutions.     

中国混合遗产的管理机制研究——以泰山为例

世界遗产是人类的共同财富,它具有脆弱性、不可替代性等特点,但是在我国世界遗产保护方面仍没有一部专门保护世界遗产的法律,以致于在管理方面产生了混乱.以泰山为例,与国内外的混合遗产进行对比分析,以借鉴可取之处,并提出了改变管理观念、统一管理、动态管理、完善法律法规等措施来加强世界遗产的管理.     

中央苏区红色旅游资源跨区域整合开发研究：文化生态学视角

红色旅游资源是革命精神的核心载体,其保护和旅游利用面临着破碎化、片段化、静态化等问题,亟需开展整合开发研究。以中央苏区核心区为例,基于文化生态学理论,采用GIS空间分析方法和修正的引力模型,研究红色旅游资源空间格局和文化生态变迁,在此基础上提出整合开发的策略,结论如下：（1）红色旅游资源点空间上呈现局部聚集特征,赣南苏区形成章贡区、瑞金市、于都县“金三角”分布格局,闽西苏区则形成新罗区、永定区、上杭县、连城县“银菱形”分布格局;（2）闽西和赣南苏区各重大事件红色旅游资源点在空间上8.9~106.6 km的范围内,形成带状或面状的文化生态基底,并呈现一致向服务业主导型转变的发展态势;（3）红色旅游资源网络联系方向与服务业主导型文化生态方向错位发展,这是赣南和闽西红色旅游资源内部网络联系度较强,跨区域网络联系度较弱的重要原因。在此基础上,遵循红色旅游资源文化生态空间一体化、文化生态演变全域化、文化生态发展动态化的原则,提出空间集聚区优先整合开发、高发展指数红色旅游资源跨省域优先整合开发、跨主导类型关键节点优先整合开发三个整合开发对策,以期促进中央苏区红色旅游高质量发展。     

世界三大黑土区水土流失与防治比较分析

论文首先明晰了黑土及黑土区的概念与范围界定,将中国东北黑土区分为典型黑土区与黑土区两个层次。在此基础上对世界三大黑土区在成土条件,开发利用过程、水土流失及水土流失防治模式方面进行了对比分析。通过比较分析认为:在自然条件上虽然三大黑土区具有一定的相似性,但我国东北黑土区由于地势起伏相对较大,更易遭受水土流失的危害;国外两大黑土区大规模的开发利用比我国黑土区相对早一些,大规模的农业开垦与不合理的耕作方式是世界三大黑土区水土流失与土地退化的主要原因;国外两大黑土区主要以风蚀为主,我国东北黑土区则是以水蚀为主,但风蚀面积也较大;国外两大黑土区在耕作制度、土地使用政策、水土保持资金投入、水土保持宣传教育及科学试验等方面已经采取了相对有效的措施,我国在这些方面还相对滞后。通过对国外黑土区水土流失治理的借鉴与思考,提出了我国东北黑土区在水土流失防治方面亟待解决的几个问题。
