초록

국내에서의 골재자원 필요성은 1990년대 이후 경제성장에 따라 점차 중요하게 되었으며, 최근에는 기업도시, 혁신도시, 행정복합도시 등의 기존 도시외의 신도시 건설이 활발하게 이루어지고 있어 국내 골재자원의 필요성은 지속적으로 증가하고 있다. 이들 신도시 건설에는 시멘트, 모래자갈 등과 같은 건설 부자재들이 안정적으로 공급되어야 하는 것이 필수조건이다. 이에 따라 이 연구에서는 골재채취법이 제정된 이후 수집된 골재채취통계자료를 기반으로 국내 골재의 수급현황과 향후 전망을 파악하는데 있다. 90년대 초반 총 골재 생산량의 약 25% 내외는 하천골재에서 20~25%는 바다골재에서 약 45% 내외는 산림골재에서 공급되었으며, 육상골재와 비허가 신고골재에서의 공급은 10% 내외의 규모이었다. 그러나 현재는 하천골재의 공급은 급격히 감소하였으며, 선별파쇄가 이를 대체하고 있다. 권역별 현황을 보면 수도권 지역이 항상 가장 많은 골재를 채취하고 있으며, 충남, 경남권의 순으로 골재의 생산이 많다. 생산이 적은 지역은 전북, 강원, 제주권이다. 상기 상위 3개 권역에서의 골재 채취비율은 약 50%이며, 하위 3개 권역에서는 10% 내외로, 사회 간접기반시설 확충과 같은 건설경제가 주로 광역시 주변의 인구밀집지역에 집중되고 있음을 알 수 있다.
