| The cycle of heavy metal, copper, was investigated in dynamic grassland ecosystems at a steady state in a Zoysia japonica and a Miscanthus sinensis ecosystem in Mt Kwanak, Korea. Total average storage amounts in Z. japonica and M sinensis grasslands were copper 23.92mg /$m^2$ and 51.82mg /$m^2$ respectively. Estimates of decay constants for based on experimental and mathematical model, were 0.18 in Z. japonica grassland, and 0.30 in M sinensis grassland. Decay half time of copper were 3.85 years in Z. japonica grassland and 2.31 years in A'. sinensis grassland. 95% decay times of initial copper amounts in Z. japonica and A'. sinensis were 16.68 and 9.99 years. Needed times to decay almost all of elements in Z. japonica and M sinensis grassland were 27.80 years and 16.65 years respectively. The copper was losed more rapidly in M. sinensis than in Z. japonica grassland. Key words: Cycle of heavy metal, Copper, Zoysia japanica, Miscanthus sinensis, Mt. Kwanak, Decay constants |
