臺北市轄內具水保局發布之50條土石流潛勢溪流,而該土石流之潛勢處理等級之調整,係依據現地調查中所得到的現地狀況,將評分因子分為土石流發生之發生潛勢因子,及其所造成之保全對象危害度因子兩部份加以考量,分別針對個別因子對整體潛勢評分之影響進行調整與測試來分配權重。然本研究考量臺北市為人口密集之都市計劃區域,防災處理等級除循前項規範外亦需考量該政策實行之外部成本,因此以安全危害度因子此變項比例分配進行提高,而調整為土石流潛勢溪流優先處理評分=(發生潛勢因子x40%)十(保全危害度因子x60%),經調整後優先處理順序為高者有4條,優先處理順序為中者有8條,優先處理順序為低者有13條,其餘為持續觀察。
Taipei within its jurisdiction with Soil and Water Conservation Bureau release 50 potential debris flow torrents, the debris flow potential treatment level adjustment, were based on in situ investigation in situ conditions, the ratings factor divided into mudslide occurred occurrence potential factor, its preservation of objects caused harm factor to be considered, to assign weights to adjust and test the impact of individual factors on the overall potential score. Contingent of this paper, we consider the Taipei city is a densely populated area of urban planning, disaster prevention and treatment level in addition to follow the preceding paragraph specifications should also consider the external costs of the policy, so this variable proportion allocated to improve safety hazards degree factor, and the adjustment for the mudslide potential rivers priority score = (occurrence potential factor x40%) ten (preservation of the criticality factor x60%), the higher order of priority after adjustment for four priority order in 8 priority order of 13 for low, and the rest continued observation.
