Abstract

The flora of resource plants in Middle and Northern region of Yangsan-si were investigated for 7 times from March to Sept., 2009. The study indicated that, based on voucher specimens, the flora of this area consist of 427 taxa in total; 90 families, 256 genera, 376 species, 4 subspecies, 41 varieties and 6 forms. The resource plants in this area were categorized by their use into 9 groups inclusive of 1 unidentified group. Resources plants which were investigated in this area were 167 edible, 132 pasturing, 118 medicinal, 98 stainable, 52 ornamental, 15 timber, 6 fiber, 2 industrial taxa and 101 unknown resource plants, respectively. Also, there were remarkable plants such as 16 taxa of Korean endemic plants and 36 taxa of specific plants which were designated by the Ministry of Environment. Furthermore, 22 taxa of naturalized plants were observed in this investigated area where Urban Indexn UI) was 8.9%. Although the ecological status of investigated area was comparatively well conserved, the degree of (UI) was relatively high. Based on the results of this investigation, UI has been rapidly increased due to urbanization and construction of recreation objects in this area.

2009년 3월부터 2009년 9월까지 경상남도 양산시 일대의 관속식물 및 자원식물분포조사를 수행하였다. 본 조사를 통해 확인된 조사지역 내의 소산 관속식물은 90과 256속 376종 4아종 41변종 6품종으로 총 427분류군으로 확인되었다. 조사 지역에서 분포하고 있는 427분류군의 식물자원 유용도를 분석한 결과 식용자원식물이 167종류, 섬유용 자원식물이 6종류, 약용자원식물이 118종류, 관상용 자원식물이 52종류, 초지 자원식물이 132종류, 공업원료자원이 2종류, 염료용 자원식물이 98종류, 목재용 자원식물이 15종류, 용도가 밝혀지지 않은 식물이 101종류로 구분되었다. 이 중 식용자원, 약용자원, 초지자원, 염료용자원이 비교적 많이 분포하는 것으로 나타났다. 특기할만한 식물로는 한국 특산 관속식물이 총 16분류군, 환경부지정 특정식물종이 36분류군으로 각각 조사되었고, 귀화식물은 38분류군으로서 약 8.9%를 차지하였다. 조사지역의 식생은 비교적 양호한 편이었으나, 저지대 대부분이 농경지로 활용되며, 사찰과 많은 여가시설, 탐방객 등으로 인해 귀화식물의 분포가 빠르게 확산되고 있어 생태계의 교란이 우려되는 상황이다.
