成都市民旅游感应空间研究   总被引:1,自引:0,他引:1  
旅游感应强度是研究旅游感应空间的一个角度。通过对《成都晚报》“旅游”专刊最近 6年的统计 ,得到全国 34个省级行政区及四川省内分地区作为旅游目的地的出现频次 ,以此频次来表征成都市民对国内及省内旅游目的地的感应强度。利用感应强度从省际和省内不同尺度揭示了成都市民旅游感应空间的特点 ,并发现旅游感应空间的一些新特征  相似文献

Spatial variation in soil inorganic nitrogen across an arid urban ecosystem   总被引:4,自引:1,他引:3  
We explored variations in inorganic soil nitrogen (N) concentrations across metropolitan Phoenix, Arizona, and the surrounding desert using a probability-based synoptic survey. Data were examined using spatial statistics on the entire region, as well as for the desert and urban sites separately. Concentrations of both NO3-N and NH4-N were markedly higher and more heterogeneous amongst urban compared to desert soils. Regional variation in soil NO3-N concentration was best explained by latitude, land use history, population density, along with percent cover of impervious surfaces and lawn, whereas soil NH4-N concentrations were related to only latitude and population density. Within the urban area, patterns in both soil NO3-N and NH4-N were best predicted by elevation, population density and type of irrigation in the surrounding neighborhood. Spatial autocorrelation of soil NO3-N concentrations explained 49% of variation among desert sites but was absent between urban sites. We suggest that inorganic soil N concentrations are controlled by a number of ‘local’ or ‘neighborhood’ human-related drivers in the city, rather than factors related to an urban-rural gradient.  相似文献

The development of a Municipal Information System, or currently better known as a local spatial data infrastructure, is considered complex due to the required inter-institutional relationships. In many developing countries Geographical Information Systems (GISs) are introduced but the benefits are modest as no changes take place in technical and organisational structure of organisations. Digital databases and computer-aided design (CAD) maps are mushrooming in great variety within different private and public institutions, municipal organisations and even within single departments and with structures similar to the paper period and thus operating on a stand-alone basis.Many national mapping agencies are not able to provide large-scale digital urban base maps, while the absence or low quality of cadastres makes those basic core data sets unavailable or inaccessible. The result is that duplication and incompatible data are frequently observed and also donor-driven stand-alone projects have a limited impact through the lack of institutional embedding and are not able to mature from the project to the institutional level. However, a positive sign is that there is an increasing awareness among data producers and consumers that investments in the development of digital data sets should be combined to reduce costs and increase benefits from especially GIS, and information and communication technology (ICT) in general.Within Trujillo a long-term vision was developed to make full use of ICT and GIS to modernise all operations of the Municipality to increase the efficiency and effectiveness of its tasks. However, large investments are not feasible due to the very limited municipal budgets. To guarantee the support of the municipal council, short-term results are required. This paper describes three ‘products’ as part of the vision to develop through a step-by-step approach a local spatial data infrastructure for Trujillo.The three, rather different, products are:
1. fiscal cadastre, to increase municipal revenues through property taxation;
2. an ‘environmental atlas’ based on a compatible spatial and attribute data sets from a variety of organisations; and
3. a municipal website with interactive GIS and meta data information.
The paper concludes with some comments on the institutional and political requirements for the successful development of a local spatial data infrastructure and stresses that such an infrastructure is not a product but an incremental development process that will progress only in case such a process is simple, cost effective, user-friendly, and flexible with clear products.Political interest and institutional stability and genuine interest for inter-institutional cooperation will add much to the success of this process.  相似文献

伽达默尔对海德格尔的艺术真理学说进行解释学的重构,通过审美意识批判提出理解的真理,并以之作为艺术理论的立足点。伽达默尔指出:康德的审美趣味、席勒的审美王国、哈曼的审美感知、尧斯的审美经验将纯粹的审美意识作为艺术理论的立足点,否弃艺术的作为理解的认识的真理功能,显示了美学对于艺术理论的局限性。伽达默尔的这一批判结果对我国当代文学理论建设和发展极具启迪意义。  相似文献

In the modern western world, the discursive construction of fatherhood and everyday fathering practices has been underpinned by the spatial separation of work from home, of public from private. However, increasing numbers of employees are now working from home and a disproportionate number of these are men with young children. This article draws on new empirical research to examine the implications for fathers and for organizations as home‐working disrupts earlier spatial configurations of fatherhood and fathering practices. The article concludes that as the spatial boundaries between home and work collapse, new accommodations between fatherhood/fathering and organization are emerging. However, these are underpinned by a traditional gender division of labour in the household. More broadly, these findings confirm the inadequacy of static distinctions between public and private, showing that while such distinctions are still used to mark space and time, this is relational, contingent and unstable.  相似文献

The author presents a multivariate location model for cluster correlated observations. He proposes an affine‐invariant multivariate sign statistic for testing the value of the location parameter. His statistic is an adaptation of that proposed by Randles (2000). The author shows, under very mild conditions, that his test statistic is asymptotically distributed as a chi‐squared random variable under the null hypothesis. In particular, the test can be used for skewed populations. In the context of a general multivariate normal model, the author obtains values of his test's Pitman asymptotic efficiency relative to another test based on the overall average. He shows that there is an improvement in the relative performance of the new test as soon as intra‐cluster correlation is present Even in the univariate case, the new test can be very competitive for Gaussian data. Furthermore, the statistic is easy to compute, even for large dimensional data. The author shows through simulations that his test performs well compared to the average‐based test. He illustrates its use with real data.  相似文献
