摘要： 长白朝鲜族自治县位于吉林省东南部,鸭绿江上游的右岸,长白山的南坡。境内由海拔450米的鸭绿江谷地到海拔2559米的白头山(本县境内),高差达2100余米。全县90%的土地位于海拔800米以上,是东北位势最高的县分。本县地势高峻,由火山锥体和熔岩高原组成。鸭绿江源于白头山和望天鹅峰,放射状水系将高原开析成桌状台地和波状台地。鸭绿江沿本县南缘自东而西横流,塑出多级阶地和河漫滩。全县地势北高南低,南缘谷地自东向西倾斜,呈现以火山锥体为中心,大体呈同心园状分布的中山、高台地、低台地、台地谷缘斜坡、河谷平地等层状地形带。

Abstract: The Changbai county is situated on the south slope of the Changbai Mountains,90% of its area being over 800 metres above the sea level.The mountaineous forest resources of the cold-temperature zone markedly predominates,with obviously vertical landscape.These advantageous conditions did not give a great of economic and ecologic effects in past time because of the irrational structure of the agriculture.In this paper,based on analysis of agriculturally natural conditions,the author attempt to use the theory of system engineering to find the main factors which might bring the influences upon agriculture structure9 in order to choose an optical decision of the structure. At the same time,the paper make an approach to the qualities of land systems,providing a scientific basis for the adjustment of the county’s agricultural structure.Moreover,a discussion of the researching meathods is involved in the paper.
