摘要
以鄂尔多斯市森林资源为研究对象,以8个旗区为统计单位,从森林资源的总面积、森林覆被率、树种结构、所有制结构等方面进行统计,通过层次分析法,建立层次分析结构;经过系统分析对研究区森林布局进行综合分析与评价。鄂尔多斯市森林总量和蓄积量在明显增加,其中幼林面积占森林总面积的58%,近、成、过熟林比重偏小;林种主要为防护林,其次为用材林,经济林和特种用途林偏少;以杨树、柳树等阔叶树种为主,占乔木林分总面积的89.86%,结构简单;针叶树种主要是油松,其次是樟子松且分布面积少,占乔木林分总面积的5.56%;灌木树种以柠条、沙柳、杨柴、沙棘等为主,占林业用地面积的36.73%;森林资源个体化程度较高。
Taking the forest resources in Erdos as the research object,taking eight Qi as the statistical unit,the statistics have been done on the total area of forest resource,forest coverage,tree species structure and the ownership structure,and the hierarchical analyzing structure has been built by use of analytic hierarchy precess.The forest layout has been comprehensively analyzed and evaluated through systematical analysis.In Erdos,the total amount of forest and volume have increased obviously,the area of young forest takes up 58 percent of the total area of forest.Protective forest is the main forest type,the next is timber forest.Poplars and willows take up 89.86 percent of the total area of arbor forest.Pinus tabulaeformis is the main needle-leaved tree species.The main shrub species are Caragana korshinskii,Salix psammophila,Hedysarum mongolicum,Hippophae rhamnoides.The individual degree of forest resource is high.
