A Study on Decision Tree Classification Method of Land Use/Land Cover - Taking tree counties in Hebei Province as an example

摘要

Adopted the decision tree technology, utilized its process pattern that it imitates human's judgment and thinking and fault-tolerance feature, the author developed the decision tree classification method. In the research, first, utilized SPOT and TM, the work effectively enhanced LULC information and established the synthetic database; then, combined geosciences synthetic analysis with ground spectral feature information, utilized CART system; then the author built the decision tree model that based on the decision rules. At last, we discussed the wild use of LULC decision tree classified and stratified extractive technology. Took three counties in HeBei province as example, divided research area to classify unit (county area) by ecological division, utilized multiply data resource and geosciences rule to build the decision tree model and test and verify the method. The results demonstrated that the method improve the speed and precision of classification.
