Digital analysis of Landsat data is applied to up-dating land cover maps for the Goondiwindi district of southern, inland Queensland. The imagery was paired with climax cover maps obtained from land systems reports with analysis conducted separately for each of three climax cover types (open forest, woodland and open woodland). Computer classification using this approach produced readily interpreted and reliable results. This work demonstrates that Landsat can be used in conjunction with existing, land systems derived maps to produce data that combine the advantages of two approaches to environmental survey, the former being based on current land cover/land use and the latter on the original environment and its land use potential.  相似文献

Economic geography has undergone a number of paradigm shifts since the Von Thunen model was at the peak of its popularity in the 1960s and 1970s. This study examines the cost of moving wheat from farm to ship in South Australia and constructs a transport-cost surface for the season 1991/92. Transport costs still exert a very important influence on farm returns and land values. Governments and other authorities, when making decisions in the name of rationalisation, or microeconomic reform, should examine very carefully the spatial consequences of their actions. In the short-run at least, the farmer's world is very much a normative and partial equilibrium one. At least in respect of a significant Australian agricultural enterprise, normative and partial equilibrium models should not be seen as obsolete.  相似文献

Mining of mineral sands has taken place on North Stradbroke Island for over 40 years. Revegetation of mined areas creates a mosaic of seral classes. For a mine site in the northwest of the island, Landsat Thematic Mapper data were used successfully to map the distribution of seven seral classes resulting from mining rehabilitation. Faecal pellet counts were used to assess usage of these areas and surrounding natural forest by swamp wallabies, Wallabia bicolor. Results indicated that revegetated sites from 2 to 4 years in age were heavily used by wallabies. Older revegetated sites, dominated by senile Acacia cunninghamii, and offering little or no forage, were avoided. Swamp wallabies used revegetated sites for night-time feeding sessions and rested, during the day, in surrounding eucalypt forest.  相似文献

A number of states in the Asia-Pacific region have long been recognized to be indifferent or even hostile to the international human rights regime and to have rather poor records when it comes to protection of the right to personal integrity. Since 9/11 many of these same states have become closely involved in the US-led anti-terrorist campaign, and in the course of that involvement have been identified with the serious abuse of the personal security rights of those held in detention as terrorist suspects. This article uncovers some of the bases for that indifference to human rights treaties and why the human rights records of some of these states have become of even greater concern, particularly to domestic and transnational NGOs, in the contemporary anti-terrorist era. It argues that long-standing factors associated with intra-state armed conflict and separatist rebellions, the governmental tendency to accuse domestic NGOS of following a western rights agenda, and strong attachment to the non-interference norm have undercut official governmental concerns about the abuse of the right to personal security. More recently, emulation of the worst aspects of US anti-terrorist behaviour has given rise to a sense of impunity in some cases, and has justified a militarized response to political and religious unrest in others. Finally, the difficulties that the local human rights NGOs have had in making their case to the wider domestic populations have been compounded in a climate where many of their fellow citizens are fearful of the apparent rise in support for terrorist causes and methods.  相似文献

Blue Mountains City is a unique urban area of 75 000 people, located along a narrow mountain ridge and within a world heritage national park, between 60 and 120 kilometres west of Sydney, New South Wales, Australia. The Blue Mountains City Council is currently developing a regional city strategy to guide development over the next 25 years. All sections of a very diverse community have been consulted in the public participation process, including children aged between six and 12 years. This paper deals with the analysis of 269 entries for a children's story-writing competition organised by the council. The children had to imagine that they were adults in 2025 and write a story about what their home and city would be like at that time. The paper discusses the complex problems of consulting with children on strategic regional planning matters, and the results from analysis of these competition entries in the light of those problems. The most important issues for the children as a whole were the impact of traffic, the impact of urban development on residential neighbourhoods, places for children to play, protection of the natural environment, for which the city is famous, and the ability to keep domestic pets. One of the most significant impressions emerging from the analysis is that children were far from optimistic about the future. Thirty-five per cent of entries had a negative tone, whereas only 24% were positive. The remaining 41% were written in a matter-of-fact narrative style that indicated neither enthusiasm nor disappointment with the future of the city. The children were more or less evenly divided on whether the future would be strongly based on advances in technology, much the same as now, or based on simpler technology than at present. The technique of story writing, despite some methodological difficulties in this particular case, was a useful tool for consultation with children of this age group.  相似文献
