| Floristic composition and soil properties were analyzed in red pine($Pinus densiflora$) communities in the limestone areas. Tanyang, Ch ungbuk Province in Korea. The tree layer was composed of $Juniperus rigida, Quercus dentata, Q. mongolica$ and others as well as $P. densiflora$, all of which also appeared in soils of grinite origin The shrub layer was dominated by $Q. dentata, Lespedeza cyrtobotrya, Securinega suffruticosa, Abelia coreana$ and $Uimus davidiana$ for $suberosa$. Among these $A. coreana$ and $U. davidiana$ for $suberosa$ belonged to calcicole plant. The herb layer dominated by $Carex lanceolata$. Soil pH ranged 7.9-8.3. Total nitrogen and available phosphorus content of the soil were lower than those of noncalcareous soils. However, exchangeable calcium and magnesium content were 10 times and 2~3 times greater than those of noncalcreous soils, respectively. The difference of soil texture between top soil(loam soil) and subsoil(sand soil), and higher soil organic matter content than noncalcareous red pine forest soils seemed related to the casts forming activities of earthworms. |
