| Abstract |
For the prediction of hydrologic phenomenon, predicting future land use change is very important task. This study is intended to compare and analyze between the two different land use change models namely CLUE-S and SLEUTH3-R. The analysis of two models are performed based on the MSR value such that the model having more reliable MSR value can be recommended as an appropriate land use change prediction model. The model performance was examined by applying them to the Gapcheon A watershed. Land use map of the study area of year 2007 obtained from the Ministry of Environment was compared with the predicted land use map obtained from the two different models separately and the result from both the models showed somewhat similar results. The MSR value obtained from CLUE-S was observed to be 0.564 while that from SLEUTH3-R was 0.586. But when land use map of 2010 was compared with predicted land use map obtained from the two models in same manner, the MSR value obtained from CLUE-S` was observed to be 0.500 while that from SLEUTH3-R was decreased to 0.397 which is almost 32.3% decrease from previous value of 2007. Moreover, SLEUTH3-R was seen more sensitive in conversion of urban areas compared to other land use types. Therefore, for the prediction of future land use change, CLUE-S model is reliable than SLEUTH3-R. |
