| 中文摘要 | Models are useful tools to predict communities in watercourses based on the abiotic characteristics of their aquatic environment. For that purpose the habitat model was developed and optimized based on a dataset consisting of 300 samples collected from the upstream, middle and downstream reaches of the Lijiang River, China during two years (2009-2010). Corbicula fluminea was chosen as study object, because it is the dominant species in the study area and the distribution has eminent spatial features. Three methods, including logistic regression classification, decision trees and artificial neural networks were used to develop the model and the performance of all the modeling techniques were compared. The input variables of the model were: conductivity, turbidity, pH, water depth, velocity, manning coefficient, chemical oxygen demand. Finally, sensitivity analysis was used to get insight into the relative influence of the independent variables in the prediction process. The performances of the models were assessed through the percentage of correctly classified instances and the Cohen's kappa. The obtained results indicated that decision tree model with J48 algorithm was applied successfully in constructing a model for C. fluminea and subsequently applying it to evaluate the C. fluminea distribution. This research could give supports to the ecological regulation scheme and optimum power dispatching of reservoirs. |
