Study on herbs vegetation in the vicinity of onsan industrial complex

溫山工團 周邊 海松林의 草本植生에 關한 調査

In order to estimate effects of air pollution for herbs in the plnus thunbergii forests arrounding onsan industrial complex, this study was surveyed. number of species of herb also had a difference over 10 species by distance at the source of air pollution, and species diversity and evennes were also increasing at remote sites in industrial complex as woody plants. At the vicinity of industrial complex, $SDR_4$ of calamagrostis arundinatios arundinacea., miscanthus sinensis and cymbopogon tortilis var. goeringii were very high, and those of lianas as cocculus trilobus, lonicera japonica and paederia scandens, and phytolacca americana were low, but because of being higher than other sites, it was able to inferred that lianas had a tolerance to air pollution. The composition of biological spectra of herbs showed to type of $H-D_1-R_{2-3}-1$ at near site in the source of air pollution and $H-D_1-R_{1-3}-t$ at the other sites, and the propotion of lians forms were relatively high at the vicinity of industril complex.
