The water-level-fluctuating zone (WLFZ) in the Three Gorges Reservoir (TGR) changes seasonally because of the special hydrological characteristics and agriculture practices. Rapid land use changes have taken place in the WLFZ of the TGR, which is affected by the functions and structures of the local environmental system directly or indirectly. Land use change analysis is very important for land planning...
In order to obtain accurate, specific and timely weather forecasting image information, meteorological department want to issue weather forecast using WebGIS. With ArcGIS, the paper finished image display of the NetCDF(Network Common Data Format) data that WRF (Weather Research and Forecasting) output; combined NetCDF with ArcGIS electronic map; achieved a merger of weather forecasting information...
Sustainable development is regarded as the common goal of development by all the countries of the world. There are many approaches on evaluating the level of regional sustainable development. In this paper, back propagation artificial neural networks and GIS were applied to evaluate the levels of the sustainable development of 17 cities in Shandong province. Firstly, the writers choose 28 indexes...
Taking Shandong province as an example, the paper put forward the determination method of regional development axis and their importance and levels based on pole-axis theory. Firstly, the writers selected four regional development axes according to the conditions of choosing regional development axis, and then analyzed the ranges of the 4 axes and the cities and towns in the ranges with the method...
Direct Solar Radiation (DSR) is one of the most crucial weights of Solar Radiation, and its quantity calculation is very complex due to the influences of local topographical factors and terrain inter-shielding. DEM data as a representation of the complex terrain and multiplicity condition produces a series of topographic factors such as slope and aspect, etc. Based on DEM data and meteorological observations,...
Spatial economics(SE) research field is focused on the optimal resource allocation in space-time.Although the location theory has a long history,different from the research of time series, which has not been the mainstream of economics at all times.However, in 1991 and 1995, Krugman's Geography and Trade,Development, Geography, and Economic Theory have led the economic geography and spatial economics...
Glaciers and lakes on the Tibetan Plateau play an important role in the earth's climatic system. The technologys of remote sensing and Geographic Information System (GIS) are quite efficient for us to analyze the status and fluctuation of glaciers and lakes. In this paper, the typical glaciers and lakes variations throughout the Tibetan Plateau are investigated by analyzing the datasets from aerial...
Highways are very important to Tibet. The Sichuan-Tibetan Highway was selected as the test area in this paper. There are many geological disasters, such as landslides, rockfalls and debris flows etc., occur frequently on the Sichuan-Tibetan Highway, which does great damages to peoples' life and property. Therefore, mastering the geological status is quite essential to design and maintain the Sichuan-Tibetan...
