| dc.description.abstract | The Ocean is natural barrier in Taiwan Island, so external plants invade uneasily except drift, bird and carriage by human. Because of economical activities, Taiwan import in 1976 Leucaena leucocephala yielded in South American
Afterwards, low economical benefits as well as related lows which forbid cutting down plants randomly after establishing Kenting National park make Leucaena leucocephala in Heng-Chung area of southern Taiwan proliferate and then affect seriously the local ecology so that Leucaena leucocephala need monitor in order not to be damaged again.
In the research, the concept of Data Mining can explore information and knowledge in data which includes ground truth in 1996, buffer map of land use, buffer map of road, aspect, buffer map of land use, satellite image and NDVI. With CART, the research attempt to explore the distributions of Leucaena leucocephala and the rules of data, so as to forecast the range of distribution of Leucaena leucocephala of Heng-Chung area.
Three experimental tests include different Leucaena leucocephala dense level and amount of training set, noise reductions and SPOT images in order to explore the effects of prediction. The accuracy of experimental tests is about 80 percent. Therefore, CART can detect effectively the range of Leucaena leucocephala. | en_US |
