城市生态景观的构建研究

运用景观生态学、旅游规划学、城市规划理论来认识城市生态景观并分析其具有和谐性、整体性、多样性、畅达性、安全性、可持续性等特点，阐述以人为本、尊重地域和历史文化、生态、满足市民休闲与游憩需求等构建原则，认为重点抓好自然廊道和斑块等自然生态景观的建设、重视人工廊道和城市建筑密集区的景观效果、完善城市生态景观的空间结构体系等是构建和谐城市生态景观的重要途径。     

海南岛东南海岸带景观生态规划

对海南岛东南海岸带进行了景观生态规划。根据海南岛东南海岸带的自然资源条件与经济运行特点，将研究区划分为4个生态区：近岸热带海洋旅游区；海水养殖区；海岸平原粮牧生态区；生态林业区。各区的生态与社会经济特征不同，在利用与管理各生态区的过程中应该采取不同的对策措施，即加强宣传教育与宏观管理，以重点项目建设为契机，加快生态经济建设，优化生态经济结构。建立生物多样性管护区。     

Quantitative study of landscape patterns in homogenous carbonate rock distributed regions in Guizhou

With the utilization of GIS software, research is conducted on （a） the characteristics of cells, fragmentation, and patch fractal of landscape based on homogenous carbonate rocks in Guizhou; （b） causes of the formation of these characteristics. It has been found that under the influence of lithology, the landscape of the study region as a whole shows consistency, yet embodies distinct diversity inside. The consistency is embodied in the following aspects： （a） the preponderant landscape consists of bushes and small woods; （b） secondary landscape is characteristic of forests and grounds covered with grass; （c） of all the patches making up the study area small patches are in the majority, with positive-skewed distribution of patches-as a result, steep peaks are characteristic of the charts showing the distribution of patches. The factor of scale is not taken into account in the study of patches. The shapes of patches tend to be regular with strong disturbances from human activities, and consequently, the values of fractal dimensions of landscape types tend to get smaller. The fragmentation of patches is more apparent in landscape under influence of human activities than the one without these disturbances. Compared with regions characteristic of homogenous dolomite, the characteristics of homogenous limestone areas are described as follows： （a） low utilization rate of water resource; （b） uneven distribution of diversified landscape; （c） weak resistance against disturbances from human activities; （d） the continuous degradation, ever-increasing fragmentation, intensification of spatial heterogeneity, and the deteriorating stability of landscape.

快速城市化过程中城市土地覆被的时空动态特征

1990~2005年间,是广州市经济快速发展和城市景观变化最大的时期,以同时段TM影像解译得到广州市的土地覆被类型图,从数量结构、空间信息及位置转移和景观等方面,分析了广州市土地覆被的动态特征.数量结构的研究结果显示:在快速城市化过程中广州市的耕地、林地等自然资源的利用程度在加大,自1995年起,这种变化的趋势开始减缓;土地覆被类型之间的信息与位置的转移变化频繁,并且表现出空间位置分异的特征.景观特征指数分析结果表明:广州市城市土地覆被向破碎化方向发展,城市建设用地呈扩展之势.     

Racism and Intolerance in Eastern Australia: a geographic perspective

Racism has become a fact of life in Australia over the past decade or so, yet there are relatively few studies of its nature or extent, and still fewer on its geography. Using a social constructivist approach, this study draws on a survey of 5056 respondents to investigate attitudes to racism and cultural diversity in New South Wales and Queensland, and of perceptions of out-groups as instances of ‘strangers in our midst’. On racism, results show the presence of a continuum of attitudes ranging from generally tolerant to generally intolerant, a presence which cuts across compositional (social or aspatial) characteristics to emphasise the existence of a distinctive geography, an everywhere different nature to racist and non-racist attitudes which transcends urban–rural and traditional social layers. On the other hand, perceptions of out-groups are not uniformly correlated with presence or absence of cultural diversity. In many cases, the ability to make judgements about significant ‘others’ or out-groups has been shown to relate more to abstract notions of self and national identity, reproduced in public by mainstream news media and political leaders. In particular, it may reflect an Anglo (or Anglo-Celtic) view on nationalism, which is a hallmark of the ‘new racism’: an assimilationist or ethnocultural view of Australian society which is different from the ‘civic nation’ ideal envisaged by multiculturalism. That the geography of attitudes and perceptions people have towards and about different cultural groups is so ‘everywhere different’ has important implications for attempts to address and redress issues of intolerance in Australia.     

Rights or Containment? The politics of Aboriginal cultural heritage in Victoria

Aboriginal cultural heritage protection, and the legislative regimes that underpin it, constitute important mechanisms for Aboriginal people to assert their rights and responsibilities. This is especially so in Victoria, where legislation vests wide-ranging powers and control of cultural heritage with Aboriginal communities. However, the politics of cultural heritage, including its institutionalisation as a scientific body of knowledge within the state, can also result in a powerful limiting of Aboriginal rights and responsibilities. This paper examines the politics of cultural heritage through a case study of a small forest in north-west Victoria. Here, a dispute about logging has pivoted around differing conceptualisations of Aboriginal cultural heritage values and their management. Cultural heritage, in this case, is both a powerful tool for the assertion of Aboriginal rights and interests, but simultaneously a set of boundaries within which the state operates to limit and manage the challenge those assertions pose. The paper will argue that Aboriginal cultural heritage is a politically contested and shifting domain structured around Aboriginal law and politics, Australian statute and the legacy of colonial history.     

Nurturing Relationships: the gardens of Greek and Vietnamese migrants in Marrickville,Sydney

First- and second-generation migrants represent about 40 per cent of the Australian population. With such a large and also diverse immigrant population, urban landscapes are significantly shaped by the gardens created by migrants. Two groups of Vietnamese and Greek migrants, in the inner suburb of Marrickville South in Sydney, were interviewed to examine the relationship between migration history and garden-making practices. Garden composition was influenced by migrants’ relationship with their homeland, in terms of length of time since migration, previous garden ownership, reason for migration and desire for cultural continuity, and by the size of the garden. Gardens also varied according to country of migration. The actual garden produce and type of environment created by the garden helped to emphasise and maintain cultural relationships, provide a space of nostalgia, and give a sense of ownership and control.     

Kaleidoscoping Landscapes,Shifting Perspectives

Landscapes change in complex ways, creating surface patterns reminiscent of forms seen through a kaleidoscope. On the Earth's surface, those forms are linked to, and caused by, processes that originate with bedrock‐soil‐vegetation‐atmosphere interactions. Human‐caused alterations to landscapes are additionally tied to socioeconomic processes. Evaluation of landscape‐level processes can benefit from examining (1) the influence of disturbance regimes in altering landscape patterns, (2) the importance of considering surficial processes, (3) the subtle and cryptic spatial relations that may be present, (4) the reciprocal relationships among local processes and regional consequences, (5) the increased likelihood of some land cover transitions compared to others, and (6) the special case of landscapes with long histories of human use. These are all examples of potential fruitful arenas for interactions and represent a path for expansion of landscape ecology through accommodation of a broad range of content covered by the international GIScience community.
