The scale operation in various forms of rural land circulation in China is the way for the development of modern agriculture, and is also the basic direction of agricultural reform. The right to rural land contractual management registration makes the position of cadastral land and its interrelated information, as contractor and area, clear by Geographic Information Systems (GIS). That supplied a...
Honeypots and honeynets are unconventional security tools for the purpose of studying techniques, methods, tools, and goals of attackers. Analysis of data collected by these security tools is important for network security. In this paper, we focus on information about the locations, shapes of geographic features and the relationships between them, usually stored as coordinates and topology (spatial...
Soil erosion is an important environment disaster in black soil region due to the reclamation in past 50 years. Gullies in black soil region destroy farmland and it is a huge threatens of grain productivity security. This paper adopted Spot5 image to interpret gully distribution of study area in northern Nemoer Basin. Basic topography factors were extracted from SRTM elevation data set. The soil data...
Lacking of ability for managing and analyzing Ecology data, the currently available reservoir information system can not satisfy the demand of ecological operation. Based on the analysis of ecological environment and its influencing factors, this paper organizes and classifies the reservoir information, and builds the relationship between multiple data with contrastive analysis methods. A reservoir...
Obtaining the quantitative positioning space-based demographic and socio-economic information has the significance on assessing resources, environment and disaster. This paper presents a dynamic modeling method for rural GDP statistics data spatialization based on neural network Selecting Fangshan District in Beijing, China as the study area and taking villages as studying unit, this paper analyzes...
The differences in development elements lead to spatial disparities of regional economic development. The study, using principal component analysis and spatial autocorrelation method, has found that the economic development in Chongqing was featured with strong positive spatial autocorrelation. The positive spatial autocorrelation appears in two forms named "HH" type and “LL" type....
Geographers, demographers and other scholars have a sustaining interest in China's population distribution. The research is based on China's GIS data sets of population census in 1953, 1964, 1982, 1990 and 2000. The first part of this study is to analyze the population density patterns by various spatial analysis methods and explain possible influencing factors. The second part analyzes population...
This paper is based on the spatial interaction theory. By using the Wilson model and GIS network analysis, four ranks of tourism spatial interaction strength can be got. Then the global tourism spatial association and four types of tourism spatial association are obtained by spatial autocorrelation. The calculations of global spatial autocorrelation indicates that the significance level of global...
Most traditional epidemiological studies are based on the statistical analysis rather than spatial information. Therefore, the study combining spatial analysis with epidemiology is a promising and perspective field. This paper, based on the technology of GIS, the method of disease mapping and traditional statistics, is focus on the spatial data of influenza A virus subtype H1N1. A spatial database...
Accessibility analysis of urban emergency shelters can help support urban disaster prevention planning. Traditional accessibility measure based on gravity model is considered as geographic accessibility. And the accessibility based on space syntax is considered as geometric accessibility. How these two accessibility measures work? Are there significant differences between the accessibility analysis...
Malaysian Geographical or Geospatial Health (MyGeoHealth) is a term used to describe innovative method for monitoring environmental risk factors on human health. There are possible spatial relationship between environment and cholera outbreaks in Tawau, Sabah due to the recent outbreaks are hard to predict. Cholera is a diarrhoeal disease caused by Vibrio cholerae (Vc), which occurs naturally in coastal...
This paper aims to expand temperature and precipitation data through geostatistical interpolation techniques, and explore the changes and correlations between temperature and precipitation basing on the theory of Spatial Correlation. In the end, it provides new idea and methods for researching the spatial pattern and spatial changes of meteorological data.
There is a good correlation fractal value of high complexity and fault systems. Generally have higher value, fault systems of fractal dimension in fracture length, smaller, branch, tectonic deformation and fracture large extent. Otherwise, the fault systems have lower fractal dimension. Through the different methods of fractal dimension is different, have different meaning in the same place. In this...
Soil moisture is very important on many hydrological, biological and biogeochemical processes. To select the optimal method in this paper, five interpolation methods were compared, and then the optimal interpolation method was used to give the spatial distribution of soil moisture. The results show that (1) Ordinary kriging is the optimal method for interpolating soil moisture in Henan province. (2)...
The Zhuhai city in Pearl River Delta was chosen as a study area. The soil samples were recollected according to the sampling points of Second National Soil Survey. Based on application of geographical information system (GIS) and SPSS software, the content, distribution and its influence factors of available Cu in cultivated soils were analyzed. The results showed that: the average available copper...
The paper took Shandong Province's forest resources as the object of study, and studied on the temperature regulation of forest ecological service for different tree species and different seasons during 2000-2006 by using MODIS temperature product, vegetation index product, the field surveying data and the meteorological data in Shandong, combining with GIS. The results were as the followed: 1) Forest...
Based on RS and GIS, took 1993, 2000, 2007 and 2009 TM images as the data source, classic area (CA), pieces of Percent of landscape (PLAND), plaque number (NP), patch density (PD), largest patch index (LPI), shape index (LSI), fractal dimension (PAFRAC) were used to analyze the change of landscape from the types of Tangshan coal mining subsidence landscape. Landscape characteristics and dynamics change...
Rainfall, especially rainstorm is one of most important triggering factors to the activities of geological disasters, Which has brought great losses to people's life an property. In the support of GIS technology, taking Hubei Province,China as study area, based on detailed analysis of the geological disasters influence factors, this article imported matter-element comprehensive evaluation model to...
Today space-borne high resolution SAR sensors (e.g., TerraSAR-X, TanDEM-X, SAR-Lupe or Cosmo-SkyMed) provide SAR images up to spatial resolutions of 1-3m and even better in spotlight modes. Hence, one major issue of these missions is the development of methods to automatically derive detailed cartographic information from their data. Especially, the analysis of rural and urban areas is on demand in...
Fault system is a significant evidence of tectonic movement during crust tectonic evolution and may play an more important role in oil-gas accumulation process than other tectonic types in sedimentary basin. Carboniferous surface faults in Junggar Basin developed well and varied in size and distribution. There are about 200 faults in Carboniferous, and 187 of them are thrust faults. Chaos-fractals...
