횡성댐 수몰지역내(水沒地域內)의 식생(植生)에 관(關)한 연구(硏究) -이식대상구역(移植對象區域)을 중심(中心)으로-

A Study on Plant in Submerged Area of Hoengseong Dam -Centered with Subdivided Area to Select Plants Capable of Transfer-

본 조사 연구는 강원도(江原道) 횡성군(橫城郡) 갑천면(甲川面)과 횡성읍(橫城邑) 일부를 포함하는 지역에 횡성댐이 건설됨에 따라 수몰되어질 자연생태계(自然生態系)의 복원(復元)과 보존계획(保存計劃)의 일부로 수행되어졌다. 이식대상구역(移植對象區域)인 7개소를 중심으로 녹지자연도(綠地自然度), 식생현존량(植生現存量) 및 생산량(生産量), 종조성(種組成)과 식생(植生)에 관해 조사하였으며 그 결과는 다음과 같다. 1. 녹지자연도(綠地自然度)를 등급별로 사정한 결과 등급 0(3.1%), 1(5.3%), 2(28.2%), 3(0.1%), 5(0.2%), 7(4.6%), 7(44.7%), 및 8(13.8%)의 8개 등급으로 구분되었다. 2. 전체조사지역의 현존량(現存量)과 생산량(生産量)은 각각 88,436.3 ton/year 과 12,960.3 ton/year 이었다. 3. 조사지역의 육상식물(陸上植物)의 종조성(種組成)은 86과(科), 221속(屬), 306종(種), 1변종(變種), 3품종(品種)의 총 310종(種)으로 조사되었다. 4. 선정된 7개의 식생조사지점(植生調査地點)에서는 소나무군락이 우점(優占)하며, 그밖에 신갈나무군락, 떡갈나무군락, 상수리나무군락으로 나타났다.

This study was carried out in a part of conservative plans recovering natural ecosystem which will be submerged, as Hoengseong dam is being constructed around Hoengseong-Eup and Gabcheon-Myun. The submerged area was divided into 7 small areas to figure out what kinds of species of plants are and will be according to detailed geographic characteristics. In the center of the subdivided areas, Degree of Green Naturality, standing biomass, net 36production per year, and composition of plant species were investigated. The results are as following; 1. The surveyed area was classified into 8 degree by Degree of Green Naturality, and the appeared degree and the rate of occupation were 0(3.1%), 1(5.3%), 2(28.2%), 3(0.1%), 5(0.2%), 7(4.6%), 7(44.7%), and 8(13.8%). 2. Standing biomass was 88,436.3 ton/year and net production per year was 12,960.3 ton/year. 3. The list of vascular plants identified in this study consisted of 86 families, 221 genera, 1 variety, 3 formae and 306 species, totally summiting upto 310 species. 4. The 7 surveyed areas were largely occupied by Pinus community. In addition, there were Quercus mongolica, Quercus dentata, and Quercus acutissima communities.
