With geographic information system (GIS), the ecological water requirement for forests in the Jinghe watershed, western China was estimated.
      
Employing Arc/Info GIS, the tree species diversity and rarity, disturbance degree, protection of channel system, and classification management in the Maoershan National Forest Park were described, and used as the input factors of NN.
      
Division of afforestation site type in the watershed of Wangjiagou, West Shanxi through GIS
      
The results show that we can model the spatial changes of vegetation suitability with a combination of topographic analyses based on DEM and GIS functions.
      
We also demonstrate these spatial changes on the screen using Visual Basic language and GIS functions, which will help decision makers to have a clear view of species and site suitability changes over large areas.
      
Using the ArcView Geographic Information System (GIS) platform, a case study was carried out by selecting the population of Pinus massoniana from a needle-and broad-leaved mixed forest community in the Heishiding Nature Reserve, Guangdong Province.
      
Based on Remote Sensing (RS), Geographical Information Systems (GIS), and the Spatial Principal Component Analysis (SPCA) method, the integrated assessment and changes in the ecological environment of Daning River Watershed are studied in this paper.
      
Employing remote sensing, radiative transfer simulation, geographic information systems (GIS), land hydrological process, and data assimilation, the Chinese land data assimilation system (CLDAS) is established.
      
The priority analysis using the geographical information system (GIS) tool has revealed that castern provinces should be of high priority in the future reduction activities of dioxins release in China.
      
Geographic information system (GIS), as a useful tool to analyze and manage spatial information, has a superior advantage in this field.
      
A case study in the western part of the Liaohe River featuring a method of eco-security spatial differences (ESSD) based on GIS is developed in this paper.
      
The visual spatial differences of eco-security based on GIS enables decision makers to know the status of eco-security better in making policies for achieving sustainability.
      
In order to support the plan, the integrated hydraulic model of planning pipe network was developed based on EPANET supported by geographic information system (GIS).
      
Optimal values of population density for larger islands have been calculated using the Arcview GIS 3.3 program.
      
The digital thematic maps are based on a raster version of a geographic information system (GIS).
      
Sakhalinskii Shel'f information and analytical GIS based on observational data is used to simulate hydrological parameter values at standard horizons of stationary stations in the La Perouse Strait.
      
The input data for the model are evaluated with the use of GIS "Sakhalin Shelf" and the available reference literature on the bay oceanography.
      
Comprehensive zoning of the reservoir water area was carried out with the help of GIS technologies.
      
Integrated GIS-based estimate of plankton and benthos biomasses in the Barents Sea
      
An analogy between the methodological principles and algorithms used in geographic information systems (GIS) and micromorphometric technologies makes it possible to integrate both technologies into a single information system.
