中文摘要	本文选取塔里木河下游阿拉干断面胡杨林长期监测样地,分析胡杨林空心率、树洞特征及其在不同胸径和树高组间的分布特点。结果表明:研究区胡杨种群具有较高的空心现象,空心胡杨占调查胡杨总数量的56%,约159株·hm~(-2);胡杨空心率在不同胸径和树高组间呈显著差异,其与胸径呈显著正相关,与树高呈显著负相关。该监测样地胡杨树洞密度约560个·hm~(-2),平均每株2个;所调查的胡杨树洞大部分出现在树干上( 57.1%), 均以树干中部洞口为主( 31.3%);直径为5~ 15 cm的树洞( 38.2%)所占比例最大。总树洞数量、单株树洞数量、树洞直径等特征与胸径呈显著正相关,与树高呈显著负相关,而各树洞类型在不同胸径和树高组间的分布不同,变化趋势不一致。胡杨树洞在各方位上的分布差异显著,树洞集中分布在正西方向上。胡杨荒漠河岸林的空心发生率较为严重,且胸径越大其空穴化程度越明显。加强保育幼龄胡杨和修复退化荒漠河岸林具有重要意义。
英文摘要	We analzyed the hollow ratio of tree trunks,tree hole parameters,and its distribution characteristics among different DBH and tree height classes in a long-term monitoring plots of Populus euphratica forest at the Argan section in the lower reaches of Tarim River. The results showed that P. euphratica in the study area had a high hollow ratio,in that trees with hollowness accounted for 56% of the total individuals,with a absolute value of 159 tree·hm~(-2) . The hollow ratio of P. euphratica showed significant difference among different DBH classes and tree height classes. The hollow ratio was positively correlated with DBH,and negatively correlated with tree height. The density of P. euphratica with hollowness was 560 ind·hm~(-2) and 2 ind·tree~(-1) . Most of tree holes appeared on the tree trunk ( 57.1%) and mainly in the middle of the trunk ( 31.3%) . The hole with a diameter of 5 - 15 cm accounted for the largest proportion ( 38.2%) . The total number of tree holes,the number of tree holes per tree,and the diameter of holes were positively correlated with DBH and negatively correlated with tree height. The distribution of different tree hole types among different DBH classes and tree height classes was different,with inconsistent changing trends. The distribution of tree holes showed significant difference acorss orientations,with most of which mainly toward the west. The occurrence rate of tree hollow in P. euphratica desert riparian forest was more serious. The larger the DBH of poplar tree was,the more obvious the degree of hollow. Therefore,it is of great significance to strengthen the conservation of young poplar trees and to restore degraded desert riparian forests.
