| 摘要(中) |
台灣地區經濟建設全面發展，公共建設所需砂石料源主要係來自河川，大量急遽採取河川砂石危害河防、跨河橋梁安全及農田水利取水灌溉功能等，河川砂石急速耗竭，河川補給量遠低供應量，本研究就以往的聯管計畫及現行之公開發包、劃定公告土石可採區許可採石、中央管河川許可縣立辦理疏濬、河川疏濬採售分離等五種砂石採取方式為研究主軸。 先行介紹台灣地區河川特性、河川砂石蘊藏概況及歷年砂石供應情形，敘述聯管計畫及現行砂石採取執行方式等五種砂石採取方式，列出優缺點，訪談六位經濟部水利署及河川局之專業人士，彙整專家意見並就法令面、政策面、管理面、執行面、功能面、經濟面、社會面等七個層面加以探討，了解各種河川砂石採取方式之優缺點，提出檢討建議，以提供未來砂石採取執行方式選定之依據，最後並就工程實務應用及後續相關研究提出具體之建議。 |

| 摘要(英) |
Taiwan has made a remarkable progress in overall economic
developments in the past several decades including the
completion of numerous private constructions and public
infrastructures. The quarries in river-bed are the main source
of concrete aggregates for the construction needs throughout
Taiwan as the economic development proceeds. However, the
dramatic and excessive removal of stones of all sizes has
imposed severe threats on the safety of irrigation and
river-crossing facilities, and ultimately the river itself. The
aggregate supply from rivers had fallen and became far less than
the demand by the constructions due to inappropriate and/or
excessive exploitation from the main rivers in Taiwan since late
1990s. The research is focused on the selected 5 main rivers to study the river-bed quarry exploiting operations that have been conducted/supervised by the Water Resources Agencies and its authorized river bureaus throughout the Taiwan island. The results of the study include (1) the past, present and future supply/demand of concrete aggregate from the main rivers in Taiwan, (2) the advantages and disadvantages in general of the studied exploiting operations, and (3) the positive and negative impacts of the operations in the aspects of law/regulation, government policy, river management, exploiting execution, river function, economy, and society. The results of the study can be used as an important reference by the related government agencies for better managing the rivers in Taiwan including quarry exploiting operations from the river-bed. |
