Synthesized Weight Method for Classification of Main Rivers in China

Abstract:

Reasonably determine the weights of the various classification systems is important.to the rationality and stability of river classification results in the river classification process. In order to fully exploit the sample data information, reasonably determine the various classification index proportion, in order to fully exploit the river sample data changes of extraction index information use fuzzy analytical hierarchy process and projection pursuit method, reasonably determine the various classification index proportion, thus reflects the weight of each index factor, overall, the two methods to get the weight of each index classification combination sure rivers of combination weights. The results showed that determine the combined weight of river classification is objective and reasonable, river classification results accord with people understanding in the long river habit, the result is reasonable.
