| 摘 要： | 采用航模飞机搭载数码相机的方式,在研究区域北京市鹫峰林场上空飞行拍照获得高分辨率的遥感影像,通过后期影像校正,提取林分中林木属性以及空间属性信息,通过外业调查验证,建立线性回归模型,显著性检验P<0.05。选取混交度、角尺度和大小比等3个指数计算林分的空间结构,分析发现生长状况一般的侧柏Platycladus orientalis人工林处于由纯林到弱度混交过渡阶段,均匀分布,侧柏在竞争中处于劣势地位。生长状况较好的侧柏人工林处于弱度混交阶段,随机分布,侧柏在林分竞争中处于中庸地位,五角枫Acer elegantulum和栓皮栎Quercus variabilis等阔叶树在竞争中处于优势地位。图2表4参19

| Abstract: | High resolution remote sensing images of the study area were obtained with a digital camera bound to a model airplane. Then，images were corrected with forest characteristics and spatial attributes of Platycladus orientalis stands. Finally，a linear regression model was developed and tested based on field investigation，verification，and significance testing（P＜0.05）. Next，spatial structure of different forest stands in the survey region were analyzed using three classic spatial structure indexes: 1）index-uniform angle index，2） neighborhood comparison，and 3）mingling. Results showed that growth in P. orientalis plantations was generally in a transition stage from unmixed to slightly mixed with a favorable distribution；however，the plantations were in a weak position in the completion. P. orientalis plantations that were slightly mixed and had good growth with a random distribution，varied in the completion.［Ch，2 fig. 4 tab. 19 ref. ］ |
