Relation Between Barelands and Geological Factors

독나지(秃裸地)와 지질인자(地質因子)와의 관계(關係)

In this study, it is aimed to elucidate the relationship between the distribution of barren land in mountainous area and the geological and topographical characteristics of barren land in south Korea. To do this, the Land Use Classification Maps for mountainous areas (scale:1/50,000), compiled by the Roseources Survey Office of Mountainous and Forest Areas, Geological Maps of Korea (scale: 1/50,000), and Map of Geology of Korea (scale: 1,000,000), compiled by the construction Research Institute of Korea were used. The following conclusions have been obtained from this study. 1) Areas of strata that are most liable to dilapidation are found in such order of the broadest to broad as region of granite, granite-gneiss, and the specific stratum called the Kyongsang Stratum (named after the provinces) of the northern and southern Kyongsang Provinces comprising sandstones, gravelstones, crumblestones, and other stones similar to these species. These rocky hills occupy vast areas in size, so to speak, they are estimated to cover roughly 57% of the total barren and naked areas in the country. 2) The average size in area of barren and nated land, as one piece of land, 32 hectares of granite region, 15 hectares of granite-gneiss region and little less than 13 hectares of Kyongsang strata region were calculated.

산지(山地)에 있어서 독나지발생(秃裸地發生)과 지질인자(地質因子)의 관계(關係)를 구명(究明)하기 위하여 산림자원조사연구소(山林資源調査硏究所)에서 항공사진(航空寫眞)을 이용(利用)하여 제작한 오만분지일산지리용구분도(五萬分之一山地利用區分圖)와 오만분지일(五萬分之一) 한국지질도(圖) 및 백만분지일(百萬分之一) 대한지질도(大韓地質圖)를 사용(使用)하여 양자(兩者)의 관계(關係)를 조사(調査) 고찰(考察)한 결과(結果) 1. 화강암(花崗巖), 화강편마암(花崗片麻岩), 경상층(慶尙層)(사암(砂巖), 역암(礫岩), 혈암(頁岩)) 기타지질지대(其他地質地帶)의 순(順)으로 독나지발생개수(秃裸地發生個數) 및 면적(面積)의 율(率)이 많고 특(特)히 화강암지대(花崗巖地帶)의 독나지발생면적(秃裸地發生面積)은 전체(全體)의 57%를 점(占)하는 많은 면적(面積)을 차지하고 있다. 2. 화강암지대(花崗巖地帶)는 개소당(個所當) 독나지(秃裸地) 평균면적(平均面積)이 크고(32ha) 화강편마암(花崗片麻岩)은 중간(中間)(l5ha), 경상층(慶尙層)은 작았다(l3ha).
