  • The aim of this study was to determine the current distribution area of Robinia pseudoacacia habitat and to estimate its stand yield as well as its carbon stocks. In order to do so, the area of R. pseudoacacia distribution is obtained based on the large-scaled forest type map (1:5,000). Also, Weibull diameter distribution model is used to predict the yield of R. pseudoacacia stands. In addition, carbon emission factor is applied to calculate carbon stocks and removals. To obtain the stand yield of R. pseudoacacia, we developed estimation equation considering growth factors of the stand, e.g. mean diameter, the basal area, maximum and minimun diameter and etc. and tested it to ensure accuracy. Consequently, estimation equation derived from all growth factors have shown significance that could also be used for analysis. Site index was also established to determine the productivity of the forestland that later turned out to be ranging from 16 to 22. Based on these results, stand yield tables were drawn up. R. pseudoacacia is widely distributed in inland areas of Gyeongsang, Chungcheong and Gyeonggi provinces which covers total area of 26,770 ha. And when it is converted into carbon stocks, it amounts to 2,517,598tC with annual carbon uptake of 3.76tC/ha which is comparable to Querqus species that is known to storer large amounts of carbon. Therefore, R. pseudoacacia is also expected to serve as a viable carbon pool that would contribute to the mitigation of climate change. Furthermore, stand yield tables, an outcome of this survey would assist not only in proper management but also in sustainable management policy of R. pseudoacacia.

  • To get ecological information necessary for the prediction on succession and the silvicultural control of the black locust(R. pseudoacacia) plantation, classification of vegetation unit. competition of major species, and succession were analyzed. The results were as follows. Vegetation units classified in R. pseudoacacia forest were Quercus variabilis community, Persicaria perfoliata community, Styrax japonica community, Acalypha australis community, Typical community. Species diversity indices showed significant difference among the vegetation units. As a result of stand ordination by CCA method, arrangement of stands on Axis I was correlated significantly with altitude, sand, silt and available phosphorus contents, and that on Axis II was with total nitrogen, exchangeable calcium and kalium contents. It was judged that R. pseudoacacia plantation would be replaced by the mixed forest including Quercus spp., Acer spp., and Prunus spp. etc., native to Korea with the progression of succession as the results of analyses on competition of major species and successional tendency in R. pseudoacacia plantation.
