Abstract

This study was conducted to estimate the changes of stand diversity before and after applying three different silvicultural treatments such as selection cutting system, two-storied system, and shelterwood system. Data were collected in the natural deciduous forests in Pyungchang of Gangwon Province, Korea. Nine permanent sampling plots of 0.09 ha were established in the forests and the each of silvicultural treatments was applied to three sampling plots, respectively. Some tree variables were measured in each stand before and after the silvicultural treatments were applied. With these data, stand attributes were estimated in each stand before and after the silvicultural treatments. In this study, two different indices related to each of stand diversity indices such as contagion, DBH-difference, height-difference, and mingling were estimated and compared to analyze the differences of stand diversity among the stands before and after silvicultural treatments. As a result, total eight stand diversity indices were used to analyze the differences among structures of stands managed by three different silvicultural treatments. Duncan's multiple range test and t-test were then employed to statistically analyze the difference of stand diversity among the stands. The results revealed that stand structures seem to be improved after applying the silvicultural treatments. There are significant differences in the stand diversity indices between before and after silvicultural treatments for each stand. According to the evaluation of stand diversity indices, it was confirmed that spatial structure of the stands was improved by applying the silvicultural treatments.

본 연구는 강원도 평창군 가리왕산 일대의 천연 활엽수림을 대상으로 작업방법별 시업 전과 시업 후의 임분다양성 변화를 평가하여 산림생태계 경영에 필요한 정보를 제공하고자 수행하였다. 이를 위해 각 작업방법별로 $30m{\times}30m$(0.09 ha) 크기의 고정표본점을 3반복으로 설치하고 시업 전과 시업 후의 정밀 임분조사를 실시하였다. 이 자료에 근거하여 임분다양성 지수인 집락도, 흉고직경 변이지수, 수고 변이지수, 그리고 혼효지수와 관련된 2개씩의 지수, 총 8가지 지수를 추정한 후, 3가지 작업방법에 대한 시업 전과 시업 후의 임분다양성 변화를 평가하였다. 본 연구에서는 시업 전후의 임분다양성 변화에 대한 통계검정을 위해 Duncan의 다중검정과 t-검정을 실시하였다. 임분다양성 지수를 분석한 결과 작업방법에 관계없이 시업을 통해 임분구조가 개선된 것으로 평가되었다. 또한 시업 전과시업 후의 임분다양성 지수는 통계적인 차이를 보여 각 작업방법별 임분의 공간 구조는 시업을 통해 개선된 것을 확인할 수 있었다.
