摘要:
 人工造林是干旱荒漠地区减少土地荒漠化的重要手段。不同造林措施影响着植物存活率及植物的生长状态。为探究干旱荒漠区不同造林方式对梭梭地上构件在空间排列方式的影响,采用枝系构型的理论和方法,对吉兰泰不同造林方式中梭梭的分枝构型特征进行研究。结果表明:1)不同造林方式下的梭梭分枝构型有较大的差异,主要体现在分枝长度、角度、枝径、体积等变化明显 ;2)不同造林方式中梭梭的分枝长度、枝径、体积总体均呈现随枝序级别的增加其值减小的趋势,但各级别分枝角度表现出不规则分布的特征;3)不同造林方式中梭梭的总体分枝率表现为:水冲造林>机械穴植造林>抢墒造林,分别为6.51±1.95、2.88±0.77、2.23±0.61。抢墒造林的梭梭枝系长度、枝径、体积、分枝能力均优于水冲、机械穴枝造林,能够在有限的自然资源中获得更多的空间资源。因此,抢墒造林技术是更适宜吉兰泰当地梭梭生长的人工造林方式。
Abstract:
 Afforestation is an important mean to reduce desertification in arid area.Different afforestation measures affect the survival rate and growth state of plants.In order to explore the influence of different afforestation methods on the spatial arrangement of Haloxylon ammodendron aboveground modules in arid desert area,the branching architecture characteristics of H.ammodendron in different afforestation methods in Jilantai were studied using the theory and method of branching architecture.The results showed that 1) there were very significant variations in branching architectures of H.ammodendron among the three afforestation methods,especially remarkable in branch length,diameter,angle,and volume.2) The branch length,diameter and volume of H.ammodendron in different afforestation methods all showed a decreasing trend with the increase of branch order level except for random branch angle.3) The overall bifurcation ratio of H.ammodendron in different afforestation methods was in the order of water jettng>mechanical hole planting>planting in good water condition.The branch length,diameter,volume and branching capacity of H.ammodendron under method of planting in good water condition were better than the other two methods,which could obtain more resources in limited natural resources.Therefore,the planting in good water condition method is a more suitable afforestation method for H.ammodendron in Jilantai salt lake.
