지리산지역 산림의 공익적 기능의 계량 및 평가 = Measurement and Appraisal of Public Function of Forest in Mt. Chiri

다국어 초록 (Multilingual Abstract)

This study was intended to investigate how much public functions of forest resources to be utilized diversely.
For its goal each of public functions of forest which would be classified into function of head-water conservation, soil-runoff control, landsliding control and sanitary and recreation was measured and appraised covering Gyeongsang university forest of 4,537.82㏊ at Sancheong county, Gyeongnam. The results obtained were as follows ;
1. The function of head-water conservation was measured to be 1,351ton/㏊, which was computed by Ps = d·Rv.
Where Ps : Precipitation storage (ton/㏊)
d : Average depth of soil(m)
Rv : Rate of non-capillary porosite(%)
2. The function of soil-runoff control was measured to be 905,295.09㎡, which was computed by Se=A·d.
Where Se : Soil-runoff(㎡)
A : Area(㎡)
d : Difference of erosion depth between stocked forest and un-stocked forest(m)
3. The function of landsliding control was measured to be 21,025㎡, which was computed by Sl=1/3·A·(Sln-Slf) and Sen·(An-Af).
Where Sln : Landsliding in un-stocked forest(㎡)
Slf : Landsliding in stocked forest(㎡)
Sen : Soil-runoff in un-stocked forest(㎡)
An ; Area of landsliding in un-stocked forest (㏊)
Af : Area of landsliding in stocked forest(㏊)
4. The function of sanitary and recreation was measured to be 3,211,199,669 won and over, which was computed by Vr $gt; Vf,
Where Vr : Value of sanitary and recreation
Vf ; Value of wood production
5. The function of head-water conservation was appraised at 15,530,840,211 won, which was estimated as Aw=Ps·c/w.
Where Aw : Value of function of head-water conservation
c : Construction cost of dam
w : Water storage(ton)
6. The function of soil-runoff control was appraised at 8,057,126,301won, which was estimated as Ae=(Sen-Sef)·c.
Where Ae : Value of function of soil-runoff control
Sef : Soil-runoff in stocked forest
7. The function of landsliding control was appraised at 187,122,500won, which was estimated as
Al={Sl+(An-Af)·Sen}·c.
Where Al : Value of function of landsliding control
