Abstract In order to study evaluation methods on eutrophication of small landscape waters, we take 10 garden landscape waters of Shanghai into account. We use principle component analysis method to filter out the evaluation factors and determine the evaluation criteria. The GA-BP model of Matlab is used to evaluate totally 40 data sets, which contains the data of 10 gardens under four seasons. Our results demonstrate that it is consistent with that AHC-PCA. Five evaluation factors, including Chla, TP, TN, CODMn and SD, can be easily obtained, as a result, our model could be widely extended.
