摘要

本研究以台灣之木麻黃及相思樹下層植物為例，發展出新的數值分析概念S/C之關係，發現台中港與四湖樣區S/C值相差之倍率最大，達10.12倍，台中港與四湖之比值亦達11.12倍，相思樹通宵及恆春半島樣區則差2.66倍，顯見C量越高則S/C值越小，因此在增加下層植物碳量的同時，也會對種類之多樣性有負面之相關。生物量與種數呈現不顯著之負相關，數值為－0.136。

In this research, we developed a new approach of using the species/carbon (S/C) value to numerically analyze the properties of understory plants under Casuarina and Acacia confuse plantations in Taiwan. The difference between the S/C values in Taichung Harbor and the Sihhu area was the largest, at 10.12. The ratio of Taichung Harbor to Sihhu was as great as 11.12. The difference of Tongsiao and the Hengchun Peninsula for Acacia confusa was 2.66. The S/C value obviously decreased as the C value was increased. Meanwhile, the variety of species was reduced with the increasing C value and showed a negative correlation. The correlation between biomass and species was not significant, with a correlation coefficient at -0.136.
