지리산 주요 활엽수종의 (闊葉樹種) 엽면적 (葉面積) 추정식에 대한 연구
김시경,이경학 ( Si Kyung Kim,Kyeong Hack Lee ) 한국산림과학회 1985 한국산림과학회지 Vol.70 No.1
This paper is concerned with estimating equations of leaf area(A) obtained from linear measurements - leaf length(L) and leaf width(W) - on the leaves of 13 species composing a natural mixed stand in Mt. Jiri. This method is known to be rapid and non-destructive in estimating leaf area. The equation of A=bLW is frequently used in rough and rapid estimation. Each species in this study has its own coefficient b according to its geometrical leaf shape. The range of coefficients of 13 species was 0.579 to 0.717. This means that the relationship A=2/3LW is suitable to most broad leaf species in a natural mixed stand in Mt. Jiri. When more precise estimation of leaf area is needed, full regression equation is used. In this study, the form of log A = b_0 + b₁ log LW was the most precise estimation equation in 8 species. In addition to this, the form of A = b_0 + b₁LW and A = b_0 + b₁L² + b₁W² were founded to be suitable for estimation of leaf area. In comparision of these two forms, the determination coefficient were about the same, but the F-value of the former was greater than that of the latter. Therefore, the use of the former seems to be more reliable and practical.
