In order to avoid the interference of plant growth, the dry weight of Angular-fruit Fig and Thorny Bamboo must be evaluated by other measurements which can obtain nondestructive physical factors. Angular-fruit Fig and Thorny Bamboo are dominant plant on the mudstone area in South Western Taiwan. To get the growth model of dominant plant, the technique of sustainable and nondestructive dry matter estimation model must be developed. The relationship between dry weight of leaves and other physical properties need to be established in advance. Six kinds of physical properties on the leaves of Angular-fruit Fig and Thorny Bamboo were measured.The product of leaf length(L/cm) and maximum width(W max/cm), defined as C values, have high correlation coefficients with dry weight (Dw)or leaf area. The linear function between natural logarithm of dry weight(g) and natural logarithm of C values(cm2) was the best fit model.This model of he nondestructive technique for growth amount is simpler, accurater, rapider, and cheaper than other methods.
