Effects of climate change on slopeland disasters in the future are related not only the frequency of extreme rainfall but also population and economy development. Therefore , to evaluate the effects of climate change on the potential of slopeland disasters , it is necessary to evaluate the effects of rainfall and the information related to population and economy development , so that slopeland disaster prevention plan may be better proposed . Hence, in this study, the watersheds of Kaoping stream and Chenyulan stream are selected as the study sites, the information of hydrology , physiographic, population and economy in the sites are to be collected , and surface cover are to be recognized to establish models for evaluating the potential of landslides and debris flows . Then, the information of future scenario are used to access the effects of climate change on the slopeland disasters of landslides and debris flows in the watersheds of Kaoping stream and Chenyulan stream in the future . Finally, according to the findings in this study, the strategies are to be proposed to make or adjust plans for slopeland disaster prevention.氣候變遷對坡地防災規劃之影響評估
