본 연구는 환경인자를 이용하여 남부권역(전라북도, 전라남도, 광주광역시, 경상남도, 부산광역시, 울산광역시 및 제주특별자치도)의 주수종인 삼나무의 지위지수 추정식을 개발하고 적지면적을 추정하여 기후변화에 대비한 새로운 산림자원모델을 개발하고자 수행하였다. 이에 산림입지도와 자동기상측정장치(AWS)를 이용하여 626개소 삼나무 표준지에 대한 67개의 환경인자를 도출하여 최적의 지위지수 추정식을 조제하였다. 추정식에는 8개의 환경인자(A층 토색, B층 토색, 3월 평균기온, 능선대계곡비, 모암, 8월 평균기온, 해발고도, B층 토심)가 독립변수로 사용되었으며 결졍계수는 0.466으로 분석되었다. 지위지수는 12부터 18까지 분포하였으며, 남부권역의 현존 삼나무 임분 중 지위지수 중(16)이상인 적합성 비율은 20.1%로 나타났고 면적은 225,263.8ha로 산출되었다. 주로 내륙의 해발 600m 이하인 계곡부 또는 풍노출도가 낮은 곳이 적지인 것으로 나타났으며 전라북도의 변산반도, 임실, 정읍, 순창, 전라남도의 담양, 곡성, 화순, 영암, 경상남도의 함양, 산청, 합천, 제주도의 한라산 동사면 및 남사면의 산복 지역이 이에 해당되는 것으로 조사되었다. This study was conducted to develop new forest resources model for Climate change. For this, it was performed to develop site index equations and estimate productive areas for Cryptomeria japonica of major species in the Southern area using environmental factors. The 67 environmental factors about Cryptomeria japonica, 626 sites were obtained form a Forest Site Digital Map and Automatic Weather System(AWS). It was regressed on site index equations. Eight environmental factors(A horizon soil color, B horizon soil color, March mean temperature, ridge-valley rate, country rock, August mean temperature, altitude above sea level, B horizon soil depth) were selected as independent variables, the result showed that the coefficients of determination were 0.466. The site index was ranged from 12 to 18. Compliance ratio about the site index more than 16 was showed 20.1%, and the area was calculated 225,263.8ha. Right land was valley about 600m below sea level in inland or area of low wind exposure.

The purpose of this study is to develop a forest resource model and prepare for the new afforested land and climate change through estimating the site index(among several methods, the site index is a typical way to digitize the quality of locality). It also aims to evaluate a suitable site with the warm temperate zone’s three major species(Quercus acuta, Castamopsis sieboldii, Machilus thunbergii) that grow in the southern region including the Jeju special self- governing province and island region. Each specie used 32 site environmental factors and the average height of 5 dominant trees`` for the growth model. The partial correlation analysis using the sample tree collected for evaluation was also conducted . In addition to the partial correlation analysis, the study used the on site stem analysis data and made the final site index functional formula by analyzing the site condition which affects the site index table and curve. Also, this study calculated the suitable site space and tabulated the suitable tree figure on site by using the site index functional formula. As a result, the suitable site of Quercus acuta turned out to be over 10 site index 82,522ha, the Castanopsis sieboldii over 12 site index 60,801ha and the Machilus thunbergii over 12 site index 219,442ha. Quercus acuta was evenly spreaded along the coast and island region that had a high annual average minimum temperature, and was located within 20km from the coastline under 400m elevation. The Castanopsis sieboldii’s suitable-site was mainly spreaded out in the island and coastal region, but it also grew up into the inland and its suitable-site showed a large gap between the annual maximum and minimum temperature. The analysis showed that the growth suitable-site of the Machilus thunbergii turned out to be a place abundant with rainfall in the early spring season, and less than 200m elevation along the coastline and island regions. The coefficient of determination was 0.306, 0.271, and 0.259. The result of this study can be used to decide the forest resource composition and establish management plans through estimating the site index of the warm temperature zone’s three major trees and thus help select a suitable tree on a site through evaluation.
