ABSTRACT
This study investigated correlation between thinning intensity and growth in Larix leptolepis plantation which is located in Yangdong-myeon, Yangpyeoog-gun, Gyeonggi-do, Korea. In 1997, 4 sample plots with the size of 20mx20m were established and thinned with the different thinning intensity of 0%. 10%.20%. 40%. Location. dbh. and height of individual trees were measured in 1997 and 2007. As a result. it is proven that thinning intensity significantly influence dbh and height growth. stand structure. Especially dbh growth was shown to be strongly promoted by increasing thinning intensity.
Key wards: thinning intensity. Larix leptolepis. height. dbh. growth. structure.
