摘　　要：借助1997年二类调查数据,运用趋势面分析方法,在arcinfo的支持下,采用统一网格样点采样法,通过对不同景观类型的生态潜力进行量化,对吉林省汪清林业局金沟岭林场的森林景观要素空间分布的趋势进行了研究.结果表明:在金沟岭林场范围内,水平地理位置对景观要素空间分布的影响极为有限,景观要素空间格局更多地受地形特征和干扰格局的综合控制;研究地区海拔、坡向和坡度是控制景观要素空间分布格局的主要因素;在不同海拔带上,坡向和坡度对景观要素空间分布的作用在方向和强度上都有明显差别.The space distribution trend of forest landscape elements on Jingouling Forest Farm of Wangqing Forestry Bureau, Jilin Province was studied based on ClassⅡ investigation data of forest resources carried out in 1997 and by means of trend surface analysis method. The study was done by quantifying the ecological potentials of different landscape types through standard network sampling approach supported by ArcInfo techniques. The results showed that the horizontal geographical position did not impact significantly on the spatial distribution of landscape elements, while the spatial pattern of landscape elements was mainly and comprehensively determined by topographical features and interference pattern. The altitude, aspect and slope gradient were the dominant factors to control the spatial distribution pattern of the landscape elements in the study area. On different elevation zones, the influence of slope aspect and gradient would differ significantly in the orientation and intensity upon the spatial distribution pattern of landscape elements.
