随着中国经济的高速发展以及国际影响的日益扩大,对外汉语的普及教学也变得越来越重要。在这样的背景下,学习者在母语环境中习得汉语时可能遭遇到各种干扰问题。对国外学习汉语的外国学生来说,对外教材的编排及正确的语义解释十分重要。本文从“了”的本体研究和国内教材分析出发,探讨对韩汉语教材中存在的语义解释问题,加上前人的偏误研究内容,例证韩国学生对“了”的固定认知,最终提出富有针对性的对韩汉语教学建议,以期提出有效的教学方法,并总结出有助于改进今后对韩汉语教材的方法。

We used preliminary data to estimate the growth volume of artificially reforested Pinus densiflora in a post-fire area on three different contour conditions. We compared the growth of P. densiflora on a south-facing slope(Ssth), north-facing slope(Snth) and ridge area(Ridge), using 7 trees selected from each stand aspect. The tree height, diameter and growth volume were measured and the dry weight of each plant part were compared and analyzed. The results revealed that the total dry weight was highest on Ssth(5992.3 g), followed by Snth(4833.2 g) and lowest on Ridge(3160.1 g). The height growth was highest on Snth(285.8 cm), followed by Ssth(274.5 cm) and lowest on Ridge(211.5 cm). The diameter growth was greatest on Ssth(7.37 cm), followed by Snth(7.10 cm) and lowest on Ridge(5.72 cm). The volume growth was highest on Ssth(4257.7 cm3), followed by Snth(3750.7 cm3) and lowest on Ridge(2093.7 cm3). Therefore, we should consider and include the concept of slope orientation together with differences in habitat environments in afforestation projects when creating artificial forests with P. densiflora. These study results can serve as important preliminary data for future establishment of artificial forest of P. densiflora in a post-fire plantation.
