碩士 / 國立屏東科技大學 / 森林系所 / 96 / Natural environment in Taitung is special, making the natural soil sand disasters keep pouring in such as collapse, ground slippery and mudslides. They endanger local residents, visitor's security and economic construction in the place of the life property to cause great loss, also stop outward of the transportation contact. And due to the overdeveloping exploitation of slope ground,which encounters severity break and loses a natural equilibrium ability, Also,earthquakes are multifarious,typhoon carry pouring rain to encroach upon, with the result that swollen mountain stream delivers suddenly and violently, landslide and ground slippery, the topsoil washes eclipse to run off, the freestones silts up courses of river, causing serious disasters.
This investigative research with success Township in Taitung County is based on Duli coast watershed carrying on its watershed management and erosion control methods, in order to mainly inquire into the object, by the work area of environmental factors and attributive data, using the work method of preventing disasters by regulating mountain,of current conditions and characteristic, side ascent and infrastructure break damaged inducement and characteristic, and the side ascent stability manage result, improve measure and respond counterplans to carry on investigation analysis and the work method applicability comparison to evaluate with result benefits, sieveing suitable references and manage mode for Duli coast gather water area of a mountain disaster prevention renovation work methods and plants regrow ecosystem.
Through taking a comprehensive view of 41 engineering sample area, the area investigates inquisition actually, compling through the years towards each work area's usage of curing work method of mountain disaster prevention of applicability to carry on good and bad point and benefit analyzing result, knowing for the stable ascent face and river bed, keeping a great deal of soil sand from descending,and suppressing soil sand disasters, in regard to the work method performance with the locale irrigation concrete foundation work goes the best with carving stone work and protecting a work lengthways. But protecting a work method lengthways of carving stone work must establish solid bed work in the appropriate length to protect in order to prevent carving stone work of protecting shore breakage from causing the chain effect leading to breaking completely. However, maneuver towards structures have to be used in collocation in order to make structures safe to avoid erosion breakage of maneuver,particularly at foundation firmness processing aspect. In this way, they have the function of heiping with each other.And by adopting sinked sand pool to defend the sand facilities work method is the urgent established engineering facility for the this area. It can reduce soil sand to descend and the discharge of mighty currents. The work method of ascent plants matches up with cover soil seeding or the work method of spraying plants and plants grass seedling and seedling wood to strengthen a buffer green strips grow plants.This is the most suitable and effective work method in usage in the area.In addition to attaining to protect the result of stability of the water solid soil and side ascent,it can also promote the regional plants to get green soon.
In recent years, the weather is extreme abnormality and usually has the appearance of super and big pouring rain, which bears a great challenge towards watershed management and erosion control methods. Through the last few years of domestic and international disaster analysis, this phenomenon is already beyond artificial facilities.We can only adopt the engineer of hardware to reduce a disasters and assist with the software of evacuation.Apply carrot-and-stick ways to attain a purpose of insuring people's life and property security and national territory security.
