| 摘要(中) | 摘 要 砂石是公共建設所不可或缺的材料，河川更是台灣地區砂石主要的來源。本文研究內容收集濁水溪大斷面測量及水文資料，進行水理、水文及輸砂量分析，期能瞭解目前濁水溪防洪之效果及輸砂量情形，依據實測分析結果在民國90 年至93 年間集集攔河堰上游河段平均刷深0.35 公尺。台灣河川辦理疏濬方式最近幾年使用「公開發包模式」及「採售分離方式」，由於先前辦理招標方式一直讓民眾所垢病，其中最主要原因在於疏濬廠商有利可圖，而產生盜濫採行為，如果疏濬時土石販售業與採取土石承包商業分開，土石非屬採取者所有，並以土石總量管制方式辦理，達到嚴密管制效果，就能降低誘因有效阻絕盜採砂石發生。目前辦理開採方式「公開發包模式」及「採售分離方式」漸漸讓檢調單位及民眾所認同，所以本研究內容就「公開發包模式」及「採售分離方式」兩者開採方式之優缺點作為比較分析，最後就後續相關研究計畫作為具體建議。 |

| 摘要(英) |
Abstract Aggregate is an important construction material for concrete which is essential for construction projects and is no longer viewed as an unlimited natural resource.The river-bed quarries in major rivers in Taiwan have provided major sources of gravel which is a raw material for concrete aggregate. The study of the research collected survey and hydrology data to investigate the related hydrological characteristics of the Che-Shyi River in central Taiwan including sediment transportation analysis to better understand the current dredging operation, flood control and gravel exploitation from the river bed.Based on the field survey data, the erosion along the up stream section of the Chi-Chi reservoir in the Che-Shyi River has reached an average depth of 0.35 meter below the river bed between 2001 and 2004. Recently, “Public Bidding Process”and “Separate Exploitation and Sale Operation” have been used by the related river agencies in Taiwan to minimize the illegal gravel exploitation from the river bed of the Che-Shyi River. The separation between the gravel exploitation and sale operation implies that the exploiters do not actually possess the gravel and a lump sum control could effectively reduce the illegal gravel exploitations from the river. At present time, it is commonly recognized that the separation operation is the most feasible and effective for providing a balance between the river dredging, floodcontrol and gravel exploitation operation for the rivers in Taiwan. The results of the study provide not only useful information for better management of the river bed gravel exploitation but also recommendations for the improvement of the future related river managements of the rivers in central Taiwan. |
