Taking regional farming and animal husbandry sustainable development as the study object,the spatial and attribute databases for natural resources and social economy were built by using GIS,RS and GPS.
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.
