2009年莫拉克風災對於南台灣影響程度頗大,各地區災情嚴重,雖經緊急災害復建但至今引發之後續災害問題仍使災民生活品質受到影響。本文以屏東縣滿州鄉長樂村之八瑤部落為調查區域,亦即在屏縣200號道分水嶺附近,該地區原已有地層鬆動邊坡不穩定情形,在歷經莫拉克風災後,造成地層掏刷、房屋傾斜下陷、道路路基下滑問題更顯嚴重。由於該區已錯過分配永久屋的時機,為解決此問題居民透過陳請,縣政府邀請專家勘查,初步就部落周遭環境特性與災害現況,指出該地區地層滑動之發生原因與規模,提供相關單位後續作為之參考。調查結果發現八瑤部落處於地層向斜與背斜軸隱末端之中間地帶,又受到河溪與坑溝的向源侵蝕及流水淘刷作用,加上這些區段並無工程構造物的保護,每逢大豪雨溪水暴漲時,侵蝕及淘刷作用力加劇,道路與房屋就失去支撐而傾斜下陷,研判未來災情會持續擴大,必須儘早妥善監測、調查、規劃適當的治理對策。
The Typhoon Morakot caused seriously damage at southern Taiwan in August, 2009. After disaster recovery and make lots of disaster problem that the quality of life for victims became very bad. Bayao Tribe in Changle Village of Manzhou Township at Pintung County as a research area, which near the watershed of county road No.200, the stratum of this area have loose slope unstable situation. After Typhoon Morakot, the stratum was scour, ground surface distributed crack, house and roadbed became slant. With regret this area has missed the optimal timing on allocation of permanent housing, in order to solve all problems, by the expert investigation, investigate the environment of the tribe and comprehend the reason. The causes and scale of the landslides were as a follow-up related reference of disaster prevention. The survey found that Bayao Tribe is located between anticline and syncline axis implicit end of the intermediate zone, by the stream and gully to head cutting and scouring, these sections does not have levee to protect. As heavy rainfall and swollen stream thus erosion and scouring forces intensified caused the land, roads and houses subsidence became slant. Although that future disasters will continue to expand, but must as early as possible still import an early and appropriate monitoring, survey, planning appropriate management strategies.
