It’s been a while since people have awareness of the environmental impact of climate change, especially in mountain settelements of Taiwan. Extreme heavy precipitation event was very rare in the past, we rarely saw a disaster occurrence that affect the daily life of human beings. However, due to the impact of climate change, the occurs of extremely heavy precipitation events in Taiwan are more and more frequent in the past 20 years. From once every few years to nearly a dozen times a year, including heavy rain and typhoon every summer and autumn. Taiwan has special geographical factors: narrow land, densely populated, and a high density of streams. If the slope is greater than 5 degrees or the elevation is greater than 100m, the region is regarded as a mountain area. Such an area occupies about 70% lands of Taiwan, and there are many old settlements and aboriginal tribes living here. The best-known disaster event was the typhoon Morakot in 2009, it caused serious flooding, mountain crashing, and landslides in many areas of Taiwan. These disasters in mountain settlements are the most serious, including road blockage, house inundation, water and food shortages, etc. After the typhoon Morakot, People refer to "the situation in which mountain settlements are blocked due to climate phenomena" as an "isolation effect" due to plenty of news reports. Mountain settlements that have an isolation effect are like inhabitants of isolated islands on the sea. It’s difficult for local residents to save themselves, and it is hard to obtain external rescue resources. Because of the natural landform and special socio-economic environment of mountain settlements, we need to pay attention to such problems occur. The collection of “isolation effect” data is from domestic news reports, from 2000 to October 2021. A total of 326 disasters had occurred in 151 villages(The level is larger than that of the settlement because the news media mostly reported the disaster situation in the village as a unit). The severity of the disaster ranges from mild to severe, there were also many villages where the isolation effect had repeatedly occurred in different years. This study attempts to integrate and analyze the weights of the isolation effect from past studies, at this stage, the historic isolation effect villages have been split into 270 historic isolation effect settlements. The indicators include general isolation effect, hazard, exposure, and vulnerability. Then, the weight of the analyzed indicators is used to determine the other 360 mountain settlements in Taiwan. Looking forward to clarifying the potential degree of isolation effect that may occur in the future, and providing it to the public. It is hoped that such a demonstration will allow the government to carry out more disaster reduction measures for mountain settlements, and local residents can also have considerable disaster awareness in their homes. In the future, climate change will be more abrupt, but mountain settlement residents can also live and work in peace.
