| Abstract: | According to rubber growth suitability evaluation, the new rubber planting suitability evaluation model based on the cloud theory, rough set and fuzzy neural network was put forward. By using the model, sample data of rubber planting was reduced by rough set. Then, applying fuzzy neural network can obtain the membership of each evaluation element and calculate evaluation grade. The relevant research shows that the model can scientifically, fleetly and accurately divide the study area into the most suitable area, suitable area, the less suitable area and unsuitable area. |
