摘要:

通过对原始阔叶红松林草本植物早春(5月5~20日)、夏季(6月20日~7月10日)和秋季(8月20日~9月10日)的三次调查,结果表明其物种多样性是很丰富的,一年内共有123种(包括6个变种)草本植物在该森林内出现。同时其季节变化也比较明显,早春、夏季和秋季的草本植物物种数分别为:79,101,和98;Shannon多样性指数分别为:3.1829,3.3140,2.9677;Shannon均匀度指数分别为0.7284,0.7181和 0.6473。早春的草本植物以银莲花(Anemone spp)、延期索(Corydalis spp)、顶冰花(Gagealutea)等为主,夏秋季则美汉草(Meehania urticifolia)和一些苔草(Carex spp.)占优势。草本植物一年内的水平及垂直结构也有很大变化。

Abstract

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.
