요약: 본 연구에서는 산지구분에 따른 산림의 공익적 기능을 계량화하고 그 특성을 검토하고자 산림기능구분도와 산지구분도, 2020년 기준 산림의 공익기능별 가치 평가 결과를 활용하여 산지구분별 공익 기여액을 추정하였다. 산림기능구분도와 산지구분도를 중첩분석하여 각 조합에 해당하는 면적을 산출하고 각 기능에 따른 산림의 공익적 가치 금액을 적용하여 산지구분별 공익적 가치를 계량화하였다.

산지구분별로 기능을 살펴보면, 공익용 산지의 경우 자연환경보전기능의 비율이 50%로 가장 높고 임업용 산지와 준보전산지의 경우 목재생산기능 비율이 각각 58%, 45%로 가장 높게 나타났다. 산지구분을 감안한 산림의 공익기여액의 헥타당 단가는 수원함양기능의 경우 906만원, 산지재해방지기능 1,275만원, 목재생산기능 3,004만원, 생활환경보전기능 2,111만원, 산림휴양기능 1,789만원, 자연환경보전기능의 경우 707만원으로 추정되었다. 또한 산지구분별 단위면적(ha)당 단가는 공익용 산지 4,150만원, 임업용 산지 4,040만원, 준보전 산지 4,080만원으로 유사한 수준인 것으로 나타났다. 결과적으로, 산지구분별 단위면적당 단가는 서로 유사한 수준이나 기능적 측면에서 임업용 산지와 준보전산지 모두 목재생산기능에 있어 중요한 역할을 하고 있는 것을 알 수 있다.

Abstract: In this study, in order to quantify the public function of forests according to the mountainous district classification maps and examine their characteristics, the public interest contribution of each mountainous district classification was estimated using the functional classification map, the mountainous district classification map, and the value evaluation results of each public benefit function of forests as of 2020.

The proportion of preservation of the natural environment function was the highest at 50% in the case of mountainous districts for public interest, and the proportion of timber production functions was the highest at 58% and 45%, respectively, in mountainous districts for forestry use and semi-preserved mountainous districts. The unit cost per hectare of the public benefit contribution of the forest was estimated to be 9.06 million won for the development of water sources function, 12.75 million won for the prevention of forest mishaps function, 30.04 million won for the supply of wood function, 21.11 million won for the preservation of a human habitat function, 17.89 million won for the forest recreation function, and 7.07 million won for the preservation of the natural environment function. In addition, the unit price per unit area (ha) by production area was found to be at a similar level, with 41.5 million won for mountainous districts for public interest, 40.4 million won for mountainous districts for forestry use, and 40.8 million won for semi-preserved mountainous districts. As a result, it was found that the unit price per unit area by mountainous district classification is similar to each other, but in terms of function, both mountainous districts for forestry use and semi-preserved mountainous districts play an important role in the supply of wood function.
