China found the first case of AIDS in 1985. Since then, China faces an inefficient controlling and critical situation which is just like other developing countries at past 20years. It can be seen easily from present situation of AIDS transmission that the key of AIDS epidemic prevention and control is on prevention and control of AIDS transmission speed and range. That means that AIDS should implement...
In order to guide the city's waterlogging control, it's very necessary to research the urban waterlogging occurrence rules and how urbanization affects the urban waterlogging. In this paper, we select the catchment area located in Kunming Dongfeng East Road as study area to construct the urban waterlogging simulation model based on GIS and SWMM model. The procedure of model building contains sub-basin...
This paper combines geographic information technology and casualties assessment model, research on how quickly to get the results of casualties assessment calculation. In this paper, we introduced GIS-based seismic casualties assessment system's principle and design, Five-story structure based system architecture, functional realize and other content. Use the 6.4 earthquake occurred in Ning'er County,...
Through using the ArcGIS software as the platform, and taking DEM analysis, raster calculation and spatial interpolation of spatial analysis technology as the core method, this paper selects Menghai County as the study area, combines with the Delphi method, analytic hierarchy process, fuzzy membership function, farmland Integrated Fertility Index ( IFI ) and other methods, to establish major factors...
In this article, it is explored that how to design and implement a temporal and spatial early warning model for AIDS spread on sex in Kunming (Yunnan province) by using ABM and making spatial analysis by developing in ArcEngine and ArcSDE. Obviously, the method of integration between ABM models and GIS technology is also clarified as a key technology in the text. As a result, based on a spreading...
Since AIDS was first discovered, mathematical models of the transmission dynamics of this disease have been developed to determine the drivers of the epidemic. It has become apparent that the most important factor in the propagation of the disease is the aggregate effects of individual behavior and perception of risk in a geographic environment. Agent-based models (ABM) allow one to simulate the social...
Erhai Lake has a important role for the development of the city of Dali. After the mid-70s of 20th century, the intervention of human activities causes many problems. The lake level dropped and area reduced. Water quality gets serious by non-point pollution which leads to changes in ecological environment, biological diversity and accelerate eutrophication. With the people's improving of environment...
In 1989, HIV was detected amongst injecting drug users (IDUs) in Yunnan province. Needle sharing drove the epidemic and HIV spread rapidly to IDUs in neighboring cities and along drug trafficking routes. By 2002, HIV was present amongst IDUs in all mainland Chinese provinces. It is believed that IDUs may have been the core source for all later sub-epidemics in China. Agent-based modeling (ABM) is...
At the age of post-Kyoto Protocol, international forestry carbon sequestration project not only has strongly achieved the form of harmoniously developing between economy and environment conservancy in developing countries, but also is promoting the relative research on theory and technology in Forestry Carbon Sequestration. And this paper has discussed that how to establish the Geo-Spatial Model of...
The propagation of influenza through a population is an inherent spatial-temporal process of great importance for modern society. So a spatial explicit epidemiologic model of flu is proposed for a greater understanding of the disease's spatial diffusion through a network of human contacts. The objective of this study is to develop an agent-based modeling (ABM) approach that integrates geographic information...
BACKGROUD: Since Mexico reported the first case of Influenza A H1N1 influenza patients in March 2009, Influenza A H1N1 flu spreads rapidly around the world and threats seriously to human health. OBJECTVIES: (1) Establishing an Agent-based Model (ABM) of H1N1 transmission, simulating and predicting the distribution of location, extent and development of the law of H1N1 to explore the space-time propagation...
Injecting drug use(IDU) has been the dominant route for HIV infection in China, especially in Yunnan province and the HIV epidemic is a complex phenomenon in the world today. The most profound factor in the proliferation of this disease is the aggregate effects of individual behavior and perception of risk. Agent-based modeling (ABM) is the dominant paradigm in social complex network simulation which...
The dynamic cognition or spatio-temporal simulation to geo-objects (geo-spatial objects) or phenomena' is always one of the principal difficulties owing to their dynamic complexity. To solve it to a certain extent, a new mechanism based on Geo-AO is proposed in this paper. First, the popular methods of geo-simulation are analysed and some existing problems are also summarized briefly. Then, geo-cognition...
