【摘要】 侧柏在河北省主要分布在太行山区，为揭示侧柏林分布规律并探究其适宜的生长环境，本文以河北省侧柏二类资源数据为基础，采用二元材积表，计算和分析侧柏林面积与蓄积量空间分布规律，揭示其与地形因子的关系。研究结果：（1）河北省太行山区侧柏林分布面积为1.685 7万hm~2，总蓄积量为58.31万m~3，单位蓄积为34.59 m~3/hm~2。（2）不同龄组中，总蓄积量最大的为中龄林（24.82万m~3），单位蓄积量最大的为过熟林（86.54 m~3/hm~2）。（3）不同林种中，总蓄积量最和分布最广的均为水保林（44.51万m~3,1.2813万hm~2），最小的为其他防护林（0.000 4万m~3,0.000 1万hm~2）。（4）侧柏林适宜生境为海拔600～800 m、坡度15°～25°、朝北坡地区。更多还原

【Abstract】 In Hebei Province, Platycladus orientalis mainly distributed in the Taihang mountains. In order to reveal the distribution rule of lateral Platycladus orientalis and explore its suitable growth environment in Hebei Province, this paper calculated and analyzed the spatial distribution law of the area and stock of Platycladus orientalis in Hebei Province by using the binary volume table, and revealed the relationship between the area and topographic factors. The results showed that:(1) The distribution area of Platycladus orientalis in Taihang Mountain area of Hebei province is 16 857 hm~2, the total stock volume is 583 100 m~3,and the unit stock volume is 34.59 m~3/hm~2.(2) In different age groups, the total stock volume was the largest in the middle-aged forest(248 200 m~3), and the unit stock volume was the largest in the over-mature forest(86.54 m~3/hm~2).(3) Among the different forest species, the water conservation forest(445 100 m~3, 12 813 hm~2)had the largest total stock and the widest distribution, while the other protection forests(0.000 4 million m~3,0.000 1 million hm~2) had the smallest total stock.(4) The suitable habitat for the Platycladus orientalis is600～800 m above sea level, slope of 15°～25°, north slope area.更多还原
