Variations in Ageing in Home and Ageing in Neighbourhood

This paper takes a new approach to investigating people who age in place. It provides an explanation for why people age in a place that can be useful in government and corporate planning. Our research investigates the principal factors that drive the decision of a rising number of older Australians to age in place. Many older people wish to age in place rather than move in with their children or be institutionalised. They wish to continue to be active in their local communities and maintain their existing social ties. The concept of ageing in place covers two distinct groups: those who are able to stay in their current dwellings and age in home and those who move house but remain in their local community and age in neighbourhood. Age-friendly home modification is a response to ageing in home, whereas the provision of institutional healthcare and the provision of age-suitable housing to facilitate downsizing are associated with ageing in neighbourhood. Using Household, Income and Labour Dynamics in Australia (HILDA) survey data, this research examines the mobility decisions of older Australians and identifies the major determinants of a decision to age in place. This research argues for a better understanding of ageing in place, differentiating between those ageing in home and those ageing in neighbourhood.     

Changes in regional employment in Denmark in the seventies

Nielsen, Bue and Sørensen, Peder Michael: Changes in regional employment in Denmark in the seventies. Geografisk Tidsskrift 84, 69–73. Copenhagen, January 1984.

The paper deals with regional development in employment in Denmark in the 1970's. It uses shift-share analysis to isolate elements and activities responsible for the regional dispersion experienced. In that context the paper discusses the interrelationship between manufacturing industries and public services.     

Life in de facto statelessness in enclaves in India and Bangladesh

Drawing on conceptualization of statelessness and ethnographic research on crucial insights of rightessness, this paper investigates how the politico‐geographic‐legality constructs statelessness in the enclaves in India and Bangladesh. Following the decolonization process in 1947, both India and Pakistan/Bangladesh inherited more than 200 enclaves, which comprise 80 per cent of the world's enclaves. With improved bilateral relations, India and Bangladesh officially exchanged the enclaves on 1 August 2015, and the enclave dwellers will gradually be granted citizenship rights over the next few years. In this period of transition from statelessness to statehood, this paper can be read as contemporary history. This paper will draw attention to three aspects of statelessness. First, conceptualization of statelessness not only applies to the refugeehood or de‐territorialization of people but also relates to the process of constructing transterritorial stateless people. Second, this paper will discuss the condition of statelessness constructed in a politico‐geographic‐legal trap. And finally, the paper calls for a wider empirical and critical focus on the hidden geographies of de facto statelessness.     

福建九龙江口红树林造林遇到的问题

中国的红树林在过去50年里面积锐减了近70%,恢复和发展红树林迫在眉睫,红树林人工造林是必由之路。福建九龙江口湿地资源丰富,然而在红树林造林上却遇到了一些问题,这些问题阻碍了九龙江口红树林的恢复和发展,应该引起相关部门的关注。     

分形理论在中国地理学应用的研究

1IntroductionMany natural phenomena such as zigzag coastline, various landforms, turbulent rivers, etc. cannot be described with traditional Euclid geometry, but they are of self-similarities. Fractal geometry takes the complex phenomena as its research objects and has been developed into a specific theory. So it has been praised as natural geometry. What is fractal means "irregular, fractional, fragmental" and its core is self-similarity (Wang and Cao, 1995). To characterize fractals differ…     

中国沙漠化研究的进展

中国沙质、砾质荒漠和沙漠化土地的面积达149万km², 占国土面积15%。1959年中国科学院治沙队成立到今天的沙漠所, 经历了卅个春秋。沙漠科学的研究也从空白发展成一个新学科的成长过程。为我国沙漠科学积累了丰富的资料, 培养了一支有着丰富经验又有一定理论水平的科技队伍。具有独立解决经济建设中提出的沙漠及沙漠化治理问题的能力, 并为全球沙漠化研究工作和治理实践, 作出应有的贡献。1988年6月5日世界环境日时, 联合国环境规划署授予中国科学院兰州沙漠研究所为全球先进单位称誉。我国沙漠科学研究的发展过程, 可归纳为四个阶段: 1959-1965年, 查明沙漠情况, 探索沙漠治理方法阶段。对我国主要沙漠和沙漠化土地进行综合考察究沙区自然条件与资源, 沙丘特征与风沙运动规律。1966-1977年, 以沙害治理为中心, 根据国民经济建设需要, 开展专题研究阶段。如沙区铁路修建的有关问题和沙区水土资源开发利用和开发后自然条件的变化等。1978-1983年, 以土地沙漠化问题为中心开展综合研究。干旱、半干旱地带土地沙漠化现状、发生发展过程, 变化趋势与预测, 整治措施等。1984年以后, 主要是加强对土地沙漠化变化趋势与预测, 以及整治措施的研究, 积极开展国际学术交流, 走向世界。1)建设不同自然地带沙漠化(风沙化)治理研究示范基地系统网络。2)开展半湿润、湿润地带风沙化问题的研究。3功口强对沙漠化监测和预则工作。4)在国际学术活动方面。从举办沙漠化学术讨论会、培训班、合作研究, 进而派遣专家组帮助发展中国家从事沙漠化治理研究工作。并与前述工作相适应, 出版了一系列研究成果和图件。总之, 我国沙漠研究是以干旱地带沙质荒漠的自然条件综合研究, 逐渐发展到半干旱、半湿润地带生态环境中沙漠化与风沙化问题的研究。为我国国土整治中风沙治理提供防治途径和措施。今后的研究工作, 应着重在强烈发展和严重沙漠化地区研究整治措施。建立不同自然地带整治沙漠化土地模式。达到环境健全发展和合理生态系统管理。对潜在和正在发展中的沙漠化土地发展趋势。加强监测和预测。进而提出预防措施。总结沙漠化治理经验和教训, 编著教材培训科技力量。     

Advances in applied studies of fractal theory in geography in China

The fractal theory put forward by American mathematician B B Mandelbrot (1967) supplies an effective approach to solve complex problems. The complex problems in geography have become the main positive study field of fractal theory. Based on the works of China’s geographers and the summarization of contents of fractal theory, the authors comment on the present situation of its applications to almost every branch of geography and discuss the related problems and the prospects of fractal study in geography.     

我国生物地理学研究进展

生物地理学研究是生物学和地理学交叉非常明显的部门自然地理学学科,它具有很强的基础研究特点,同时研究成果也具有很大的应用潜力。近年来,我国生物地理学基础研究在国家自然科学基金委等部门的支持下,在山地植被与地理环境、干旱半干旱区植被与地理环境、植物区系、植物物候、土壤动物与土壤生态功能、土壤生物结皮等方面开展了全面而深入的研究。同时拓展了传统生物地理学的研究方向,在植物地理学与全球变化、植物地理学与生物多样性保护、植物地理学与生态系统管理等方面也开展了大量研究。尤为可贵的是干旱半干旱区土壤生物结皮研究、典型温带荒漠区原生荒漠植被对水分改变的响应与适应研究取得了令国内外关注的高水平研究成果。
