초록/요약
Changes of the environmental factors, vegetation structure, standing biomass, water retention capacity, NPP, P/B ratio and carbon budget according to the stand age were investigated in the Quercus variabilis stand which is one of the representative forest in the east coastal region, Korea. As a result of the correlation analysis among tree age, DBH, tree height and basal areas, DBH and basal area tend to increase linearly, and tree height logarithmically according to the tree age. The litter layer, depth of soil A layer and field capacity tended to increase logarithmically according to the stand age. But the other environment factors did not show clear correlation with stand age because most of all Q. variabilis stands distributed in the east coastal region had been regenerated after disturbance such as forest fire and clear-cutting. According to the my results, twenty years after disturbance need for the development to the normal forest formed by 4 stratum structure. Coverage and biomass of herb and shrub layer tended to decrease according to the stand age. Stem density showed notable decrease within 10 years and the stem number per individual of tree species tended to decrease logarithmically according to the stand age. The distribution of Q. variabilis according to the DBH classes showed the reversed J - shape pattern in the early stage but those of Q. variabilis after twenty years showed the bell shape pattern. And the bell shape moved from thin DBH class to thick DBH class according to the stand age. These results represented that Q. variabilis stand had been keep up by the development of the sprouters after disturbance, otherwise Q. variabilis stand might be finally changed to the series of the Quercus mongolica or Quercus serrata stands according to the topographic factors. Most of all plant species established in the early stage and species composition did not clearly changed from early stage to late stage. The difference of the species composition tended to correlate with edaphic or topographic factors than stand age. Thses results were in accordance with the IFC model. Basal area and standing biomass tended to linearly increase according to the stand age. As the vegetation developed, runoff and sediment yield to the severe rain event were estimated dramatic decrease within 10 years age. Evapotranspiration tended to logarithmic increase according to the stand age but the difference between the early and late showed the low value. Water retention capacity of stand tended to logarithmic increase according to the stand age. Water retention capacity of stands over the twenty year showed the range from 20 to 25%. NPP of stand showed the parabola form and P/B ratio exponential decreasing pattern according to the stand age. The amount of organic carbon storage of the stand showed the linear increase. The ratio of the amount of carbon contained in vegetation showed the logarithmic increase. These results represented that vegetation was more important carbon sink than soil layer in the mature Q. variabilis stand. Annual carbon absorption capacity showed the parabola form acording to the stand age. These results were fairly accordance with the bioenergetic model during the forest succession projected by Odum(1969).
