According to 3 times investigations in early spring (5~20 May), Summer (20 June~10 July) and Autumn(20 Aug. ~10 Sept. ), the diversity of herbs in broad-leaved korean pine forest is very rich and has a greatchange in different seasons. There are about 123 species of herbs (including 6 varieties) in this type offorest. The number of species in early spring, Summer and Autumn is 79, 101 and 98 respectively; theShannon diversity index is 3. 1829, 3. 3140 and 2. 9677; and the Shannon evenness is 0. 7284, 0. 7181 and0. 6473. In early spring, the dominant species are the Early-spring-herbs such as Anemone spp. Corydalisspp. Gagea lutea, and so on. In Summer and Autumn, the dominant species are Meehania urticifolia and Carex spp. The vertical structure and distribution pattern of herbs are different in different seasons.
