摘要：臭柏是我国干旱、半干旱区广泛分布、耐寒耐旱的天然常绿灌木,能够在恶劣的生境下(沙地、陡坡)密集成片分布,形成占绝对优势的单优群落,是固沙、固土的优良树种。本文历时两年调查了我国臭柏(Juniperus sabina)群落的天然分布范围、面积及生长特征,分析了臭柏天然群落的分布与地带性土壤、区域气候因子间的关联。结果表明:臭柏天然群落的分布生境主要有3种类型,分别是:沙地、亚高山地及石质山地。在我国,臭柏的天然分布主要集中在三大区域包含八个片区,分别是西部区域的阿尔泰山(占总面积的72.46%,下同)、天山(1.66%)、祁连山(4.56%)、青海环湖沙地(0.43%),斑块面积约258.71km2;中部区域的毛乌素沙地(13.48%)、贺兰山(4.10%)、阴山中高山地(2.46%),斑块面积约65.52km2;东部区域的浑善达克沙地及其周边中低山地(0.86%),斑块面积仅2.80km2。80%的臭柏主要分布在中低海拔区域(≤1500m),但在高海拔区(3357m)也有分布。我国臭柏的平均生物量(鲜重)为43.57T·hm-2,其中以新疆阿勒泰片区塔齐段的最高,达到64.14 T·hm-2,其次依次为浑善达克沙地片区、毛乌素沙地片区、祁连山片区,青海环湖沙地片区最低。
Juniperus sabina Ant is widely distributed in arid and semi - arid area as a drought and cold resistance shrub which can densely grow in harsh habitats （ sandy land and steeper slopes） to form a sole dominant community for sand control. The two - year in- vestigation of J. Sabina Ant community have conducted to figure out its range, areas and growth characteristics ,followed by the analysis of its association with regional soil and climate factors. The results indicated that the natural distribution of J. Sabina Ant mainly con- centrated in three regions containing eight sub - areas, i.e. the western region including Altai Mountain（ account for 72.46 percent of total area,the same below） ,Tianshan Mountains （ 1.66% ） ,Qilian Mountains （4.56%） and sandy land around the Qinghai Lake （0. 43% ） ,the total area for this region is about 258.71km2 ; the central region including Mu Us sandy land （ 13.48% ） ,Helan Mountain （4.10%） and alpine of Yinshan Mountain （2.46%） ,the total area for this region is about 65.52 km2 ; the eastern region including Hunshandake sandy land and its surrounding low mountains （0.86%） which is about 2.80 km2. About 80% ofJ. Sabina Ant mainly grow in low altitude areas （ ≤ 1500m）. The mean biomass of J. Sabina Ant （fresh weight） is about 43.57T . hm-2, of which the bio-mass of that in Taqiduan,Altai municipal of Xinjiang Urumchi Autonomous Region,is the highest and up to 64.14 T.hm-2 ,followed by Hunshandake area,Mu Us sandy area and Qilian Mountains area,that of the Qinghai Lake sandy area is the minimum.
