摘要

台灣北部地區之河川砂石已全面禁採，所需料源半數以上須仰賴中部供應，由於運輸距離長達150至200公里，除增加成本外，同時衍生許多交通問題。在未來陸上砂石為主要供應來源情況下，希望藉此研究有助加速推動開發，就近供應北部使用，建立區域供應體系。整體而言，北部陸上砂石資源分布面積廣，蘊藏量亦豐，但先天受地質因素影響，品質差異大；後天又有許多開採限制，真正能夠開採區域仍極為有限。本研究認為平地砂石開採如果能解決「回填料」問題，妥善做好回填工作；坡地砂石與碎石母岩之開發能兼顧土地利用，砂石採馨後將土地加以適當整復規劃，提升土地二次利用價值，都有很高的開發潛能。

It is prohibited to quarry in the rivers of northern Taiwan. Market needs are supplied mostly from central Taiwan with a transportation distance about 150-200km. It is, thus, imposing several issues such as transportation cost and highway burden. Therefore, in this paper, aims are concentrated at the land aggregates other than the river aggregates. Authors expect a local supply system would be formed to make use of the resources in northern Taiwan. In general, aggregate resources in northern Taiwan is plentiful. Disadvantages are due to the quality variation and environmental restrictions. It is concluded that in case a proper plan on refilling materials for excavation of plain aggregates is laid and a secondary reclamation plan of the land-utilization for excavation of slopeland and stratigraphic aggregates is also laid, development of land aggregates would be highly evaluated.
