초록

이 연구는 임도 개설 전·후 년차별로 식물상과 식생의 변화를 분석하고 관리 방안을 제공하기 위하여 전북 무주군 설천면 미천리에 소재한 민주지산 임도를 대상으로 임도 개설 전년도인 2012년부터 임도 개설 후 2022년까지 7차례에 걸쳐 수행되었다. 임도 개설 조사구간 내의 식물군락은 북서사면에서 신갈나무군락, 남서사면에서 굴참나무군락과 일본잎갈나무군락으로 구분되어 남서사면과 북서사면에서 군락의 차이를 보였다. 임도 개설 전·후 년차별로 식물상의 변화는 임도 개설 전인 2012년도 총 66분류군(44과 59속 51종 13변종 2품종)에서 2015년도에는 207분류군(71과 153속 176종 27변종 4품종)으로 141분류군이 증가하였고, 2022년도에는 278분류군(78과 172속 242종 1아종, 31변종 4품종)으로 212분류군이 증가하였다. 특히 임도절토사면과 임도연접사면부의 조사구에서는 년차적으로 높은 식피율과 새로운 분류군의 증가를 보였는데, 이는 임도 개설에 따른 광량의 급격한 증가와 귀화식물 및 1년생 초본류의 유입으로 인해 일어난 현상으로 사료된다. 임도 개설 10년후 연차적으로 조사된 식생 조사 결과를 보면, 임도 개설 초년도에는 식피율과 종수가 빠른 속도로 증가하다가 일정 기간이 경과 하면 식피율과 출현 종수는 줄어들고 안정된 숲이 형성되어 우점종의 비율이 증가하였다. 특히 임도연접사면에서 관목층과 초본층을 살펴보면, 임도 개설 직후 몇 년간은 초본층의 식피율이 현저히 증가하다가 시간이 경과 할수록 초본층의 피도는 감소하고, 관목층의 피도가 현저히 증가하였다. 그리고 임도산지사면에서는 초본층과 관목층의 피도는 현저히 감소하고, 아교목층과 교목층의 피도가 증가하였다.

This study was conducted for 10 years from 2012, which is a year before the forest road construction in Minjujisan, to 2022 to analyze annual changes in flora and vegetation before and after the forest road construction and to provide strategies for management. The plant communities in the research sites along the forest road showed the differentiation between slopes with Quercus mongolica community on the northwestern slope and Quercus variabilis and Larix kaempferi communities on the southwestern slope. A total of 212 taxa have increased for number 7 between before and after the construction from a total of 66 taxa (44 families, 59 genera, 51 species, 13 varieties, and 2 forma) in 2012 and 207 taxa (71 families, 153 genera, 176 species, 27 varieties, and 4 forma) in 2015 to 278 taxa (78 families, 172 genera, 242 species, 1 subspecies, 31 varieties, and 4 forma) in 2022. It is noteworthy that the vegetation cover and the introduction of new taxa had been expanded in the sites adjacent to the construction, which is likely caused by the significantly increased amount of light and the introduction of annual herbaceous and naturalized plants after the construction. The results of 10 years of current study reveal that the vegetation cover and the number of new taxa had rapidly increased in earlier years after the construction, slowly decreased later on, and finally formed a stable forest with the increase in the ratio of dominant species. The vegetation cover of the herbaceous layer immediately increased on the slopes along the forest road for a few years after the construction although it had continuously decreased while that of the shrub layer quickly increased. It was shown that on the hillslope the vegetation cover of tall- and low-tree layers increased whereas that of herbaceous and shrub layers rapidly decreased.
