Comparison of Some Indices of Species Diversity in the Estimation of the Actual Diversity in Three Forest Types at Namprom Basin, Chaiyaphum Province

บทคัดย่อ

Species diversity presented in a community was estimated from data sampled from it. The species diversity was calculated from a complete census of trees in a temporary plot of 40 m x 40 m, and also from sampling through point-centered quarter method. Of the four indices of species diversity compared, viz., the Simpson’s D, Shannon Wiener’s H, McIntosh’s MC1 and MC2, MC2 was found by far the best.
