摘要
在Arcgis及其3D和空间分析扩展模块的支持下,计算并探讨武夷山森林主要树种(杉木、松木、阔叶树)在地形因子(海拔、坡度、坡向)各梯度级的分布比重,采用三维立体林相透视图表达森林的地形分布特征,并对其分布进行了探讨;结果表明,地带性植被阔叶树由于受人为干扰趋向分布于高海拔、坡度陡的山地;杉木林在长年人工经营的过程中,逐渐占据林分的首要地位且主要分布在500m以下的低山丘陵;松木适生性较广,明显倾向分布于(半)阳坡;人们对森林资源的经营和管理,也对森林的空间分布格局产生较大的影响。
Considering there was a close relationship between spatial distribution of forest resource and terrain, we calculated and discussed the proportion and causes of forst spatial distribution in Wuyi mountain city based on the Arcgis and its extensional module （3D ＆ spatial analysis）, besides, we express the attributes of topographical distribution of the three dominating forest by use of three--dimensional forest form profile map. The result of this research indicated that, because of human disturbance, broad-leaved trees, which is dominant species tend to move back to higher elevation and more precipitous places; Cunninghamia lanceolata gradually took up the dominating status of forests during long-term of manual work, and mostly spread in the hill that below 500m; Pinus massoniana has a wider suitable establiabment, and incline to grow in （half-）sunny-slope, Thus it can be seen , dominant natural condition endows the forest region of Wuyi Moutain with diverse and abundance natural forest resources, in addition, terrain had become one of the significant factors that affected tree distribution, however, due to the manual management and administration, spatial pattern of natural forest had been greatly influenced.
